Mailpit Hosting Live In 5 Minutes

Mailpit hosting on xCloud gives your development and staging apps a self-hosted email testing tool that catches their outgoing mail in a password-protected web inbox. Deploy Mailpit from the OneClick catalog and xCloud starts the pinned 1.31.0 image, generates the web and SMTP passwords, mounts a volume for captured messages and publishes the web UI over HTTPS. The SMTP port is plaintext and reachable from outside, so firewall it to trusted senders.

What is Mailpit?

Mailpit is, in its README's words, a small, fast, low memory, zero-dependency email testing tool and API for developers. It acts as an SMTP server, provides a modern web interface with mail search to view captured emails, and includes a REST API for automated integration testing. It also lists HTML and link checks, message tagging, an optional POP3 server and a chaos feature that triggers SMTP errors. Self-hosted Mailpit is a mail catcher you run yourself instead of a hosted testing inbox such as Mailtrap. It is licensed under MIT.

Through xCloud, the template starts Mailpit 1.31.0, pinned by digest, with captured messages on the mailpit_data volume and the most recent 5,000 kept by default. The web UI sits behind basic auth, and SMTP needs its own username and password but is plaintext. Mailpit never delivers to real recipients, because the template configures no relay or forwarding.

From Sign-Up to a Live Mailpit In Just 3 Easy Steps

Self-hosting Mailpit normally means a container, a domain, a certificate and a way to reach an SMTP port before a single test email lands anywhere. This is the same result without assembling any of it.

Step 01
Sign Up
Create your xCloud account and pick Mailpit from the OneClick catalog. Choose a site title and domain — xCloud generates the web UI and SMTP passwords for you.
Step 02
We Deploy It For You
One click. We bring up the pinned Mailpit 1.31.0 image, mount mailpit_data for captured messages, publish the web UI over HTTPS on your domain, and publish a dedicated SMTP port on the server.
Step 03
Point Your Apps At It
Sign in to the web UI with username `admin` and the generated password from the credentials panel. Then set your application's SMTP host to the server IP and the SMTP port, username `smtp`, and the generated SMTP password.

Everything Mailpit Does, On Your Own Server

Mailpit runs in full here, capturing mail on infrastructure you control instead of forwarding it anywhere.

A Safe SMTP Sink
Every message your apps send lands in Mailpit instead of a real inbox — the template configures no relay or forwarding, so test mail stays test mail.
Read It The Way It Was Sent
Open a message as rendered HTML, plain text or raw source, with full headers alongside — useful for debugging a template as much as reading one.
Attachments, Inspected
View and download whatever your app attached to a message, without needing a real mail client on the other end.
Search The Mailbox
Find a specific message across everything captured, then mark it read or delete it once you're done with it.
A REST API For Your Test Suite
Query captured messages programmatically, so a CI run can assert on the email an app just sent instead of eyeballing an inbox.
Runs On Your Server
Captured mail lives on infrastructure you control — no vendor holding the data and no export process to go through.

What You Can Do With Mailpit

Test sign-up and reset emails
Your staging app sends verification and reset mail to Mailpit, and you read each message in the web UI instead of delivering it.
Check how an email renders
You view the formatted HTML, the source, headers and attachments, and run the HTML and link checks on a message.
Run email integration tests
A test suite sends mail and reads it back over the REST API to assert on recipients, subjects and links.
Keep staging mail off real inboxes
Mail that uses customer-like data lands in a catcher on a server you control and is pruned automatically.

Mailpit vs Alternatives

Mailtrap: Mailtrap is a hosted email testing service. Mailpit is a mail catcher you run on your own server, so captured test mail stays on a volume you control.
MailDev: MailDev is a separate mail catcher with its own OneClick page, a web inbox and a REST API. Compare it with Mailpit's mail search, tagging and HTML and link checks before choosing.
Inbucket: Inbucket is a separate mail catcher with its own OneClick page that organises mail by mailbox. Mailpit shows one searchable inbox.
MailHog: MailHog is the mail catcher that Mailpit's README says originally inspired it. Mailpit offers a REST API, mail search, message tagging and HTML and link checks.

Hear what people are saying about us

See why agencies, developers, startups, and growing businesses choose xCloud to power their projects.

xCloud works really well, I am surprised by its performance being this the release version, I have tried many paid platforms such as runcloud, cloudpages or serveravatar, as well as free platforms such as CyberPanel, CloudPanel or Hestia Control Panel and direct competitors such as SpinupWP and FlyWP. Of all those that I have tried, the platform that works best for WordPress is SpinupWP and I believe that xCloud can reach and surpass that development, its roadmap is promising. Congratulations to the xCloud team, I hope they become the leading platform in the segment, it has all the potential to achieve it!

Brian Geovanny

I've been with runcloud for the last 3 years. However, after trying xcloud for the last month, I'm switching over. They are on a roll with their setup.

Kevin Pineda

I'm moving my servers to xCloud, a cloud control panel by M Asif Rahman and the WPDeveloper team. Their roadmap looks interesting and no, there are no team mates nor API limits with xCloud! #xCloud #wordpress #hosting

How Cloud Nine Web Elevated Client Experience While Streamlining Hosting Operations using xCloud

Ed Ellingham

xCloud is like having an expert server team on call — without the big agency costs. It's given me back my time and given my clients peace of mind. Highly recommended for freelancers and small teams who want reliable performance and security.

Dumitru Butucel

xCloud isn't just a solution. It's like one of that friend who got your back when you screw things up pretty bad.

Waqar Ahmed

Trust me when I say, once people explore the potential of xCloud they gonna switch from other panels, just keep delivering the best tech, lots of love for the team 😍😍

Rahul Singh

So far my experience has been smooth like silk. I didn't imagine that configuring and managing a VPS would be so easy. As of today, I have deployed 8 sites. The support is good, and they treat users with respect, even if they ask stupid questions (myself included). For the future, I hope for greater flexibility in scheduled backups and more comprehensive and consistent documentation. I'm sure that within a few months, xCloud will become the leader in its segment. This community is amazing, and the Staff here is super helpful.

Massimo Villa

Came from cloudways then to runcloud then to xcloud. Looks like I'm staying here.

Gerson El

I've recently taken all of my Vultr-hosted sites and gotten rid of cPanel for them to substitute it with xCloud. I have to say, I'm really impressed with xCloud so far! The interface is definitely the standout feature for me.

Tony Lewis

I came from Cloudways and won't go back. Highly impressed with xCloud. Glad I gave them a chance.

Jared McDowell

I like xCloud better than RunCloud, but one thing I'll point out is that some years ago RunCloud was hungry for business, the support was outstanding, and the community was active and helped each other. Maybe it was sold, there was a change in management, or they stopped being hungry, but the quality of the RunCloud offering declined and it hasn't been moving forward quickly. My point is that currently the xCloud team has the edge and it is theirs to keep or lose

How Kevin Heinrichs Cut Hosting Costs by 84% While Running WooCommerce & Node.js Sites Efficiently

Kevin Heinrichs

I had 150 sites on cloudways and am in the process of moving them to xcloud. Much faster and better priced.

Dan Spinoza

Dear xCloud Team, I have been using xCloud for some time now and am genuinely impressed with its capabilities and the flexibility it offers by allowing users to bring their own VPS for management. It's a fantastic service, and my experience so far has been very positive. Successful migrated 5 sites on a single server. Xcloud migration tool worked great. There were few hiccups with security plugin like MalCare but disabling the plugin prior to migration worked just fine.

Rahil Maknojia

Came from runcloud. Tried xcloud and never came back.

Frequently Asked Questions

Feel free to contact us with any questions or concerns you may have.

Is Mailpit free?

Yes. Mailpit is open source under the MIT licence, and the pinned v1.31.0 tag's licence file is linked here. xCloud bills for the Cloud VPS under it, not for Mailpit, and there is no per-message fee. Captured mail never leaves your server.

Can you self-host Mailpit with Docker?

Yes, and this Mailpit Docker hosting template does it for you: the axllent/mailpit image, pinned by digest, runs as one container on your own server, with HTTPS in front of the web UI and a published SMTP port. It is not a Mailpit cloud account, so test mail stays with you.

How much RAM does Mailpit need?

Minimum requirements for Mailpit start at 256 MB of RAM, because Mailpit is a small single binary. Attachments and the message limit grow the volume. The 6 GB tier on sale here has generous spare capacity.

How do I sign in to the Mailpit web UI?

Open your HTTPS address and sign in as admin with the generated password from the credentials, which basic auth requires before any captured mail is readable. Change it in the Environment editor and redeploy, since the credentials are applied from the environment on every boot.

Does Mailpit relay or forward my test emails anywhere?

No. It captures and stores mail, and the template configures no SMTP relay or forwarding, so nothing is delivered to real recipients. Mailpit can relay or forward when configured, so leave those options unset if you want a safe catcher.

How do I point my app's SMTP settings at Mailpit?

Use the server address and the SMTP port from the credentials, with username smtp, the generated SMTP password and no encryption. Send a test message from your app and it appears in the web UI immediately. The SMTP password is separate from the web password.

Is the Mailpit SMTP port reachable from outside my server?

Yes. It is bound to the host so external apps can deliver to it, and it requires SMTP authentication, but it is plaintext. xCloud does not restrict it, so use your firewall to allow only the hosts that send mail, or only this server.

How many messages does Mailpit keep?

The most recent 5,000 by default in this template, and it prunes older ones automatically. Messages are stored on the mailpit_data volume. Treat captured mail as disposable, and raise the limit in the Environment editor only if you have the disk for it.

Can I change the Mailpit passwords later?

Yes. Change the web UI and SMTP credentials in the Environment editor and Save and Redeploy, because they are applied from the environment on every boot. Edits made elsewhere will not persist. Update every application that sends mail to Mailpit with the new SMTP password.

How do I back up Mailpit?

Back up the mailpit_data volume, which holds the message database, only if you need to retain captured messages. Test mail is usually disposable, so you can often resend it instead. Keep a private copy of the web and SMTP passwords.

Backup and restore Docker apps

How do I upgrade Mailpit?

Nothing in the catalog upgrades a running 1.31.0 install for you, and you adopt a newer template version when ready. Read the release notes, back up the volume if you need the mail, then send a test message to confirm.

Can I cancel anytime?

Yes. There is no lock-in — cancel any time. Hosting is billed monthly and charged for what you actually use, so when you delete the server the unused balance is refunded to your account, less up to 10% in payment-processing fees.
