Corsair

Legal

This covers the hosted mail service at mx.wess.dev. If you run Corsair on your own server, none of this applies to you — your data never reaches me, and you are the operator making these decisions for your own users.

The short version#

I hold your mail because you asked me to store and deliver it. I do not sell it, mine it, or train anything on it. I can technically read it, and I say so below rather than implying otherwise.

What is stored#

Your messages. Headers, bodies, and attachments, for as long as you keep them. Bodies are held in object storage; the index, folder structure, and flags are held in a database. This is the service — there is no version of email hosting that does not store your email.

Your account. The email address you sign in with, your name if you gave one, an Argon2id hash of your password, and your domains, mailboxes, aliases, and filter rules. The password itself is never stored.

Connection and delivery records. For each message: the time, the sending and receiving addresses, the connecting IP address, the size, and the result. For sign-ins: the IP address and whether it succeeded. This is what makes it possible to answer "did that message arrive?" and to notice an account being brute-forced.

What is deliberately never stored#

These are design decisions in the software, not promises about behaviour:

Who can see your mail#

You, through the webmail, IMAP, POP3, or JMAP.

Me, technically. I operate the database and the servers, and there is no architecture in which that is untrue while I am also able to fix things. What I will actually do:

Nobody else, except the infrastructure providers below, and except where a valid legal order requires disclosure. Your data is not sold, rented, or shared for advertising, and there are no third-party trackers or analytics on the panel or the webmail.

Infrastructure providers#

Running this service means other companies necessarily hold the data on their hardware:

Provider What they hold
DigitalOcean The server, the managed PostgreSQL database, and the object storage holding message bodies
Let's Encrypt Issues the TLS certificates; sees the hostname, not your mail
A payment provider Card details and billing address, when billing opens. Not in use during the beta

How long things are kept#

These are the intervals the software actually enforces, not aspirations:

Data Kept for
Messages you keep Until you delete them
Messages you delete Purged 30 days after deletion
Delivery and connection logs 90 days
Failed sign-in records 7 days
Expired sessions 30 days
Password reset and recovery tokens 7 days after expiry
Encrypted backups 30 days
Everything, after you close your account Deleted after 30 days

Deleting a message removes it from your mailbox immediately. It is then purged permanently on the schedule above, and disappears from backups as those age out.

Security#

Mail is encrypted in transit: implicit TLS on the submission, IMAP, and POP3 ports, and STARTTLS on the MX and submission ports. Where a sending or receiving server does not support TLS, mail still flows in the clear — that is a property of email itself, and no provider can force the other end to encrypt.

Passwords are hashed with Argon2id. Backups are encrypted before they leave the machine. The panel and webmail are served with a content security policy, and rendered mail is sanitised on the server against an allow-list before it reaches your browser. Remote images are withheld by default, because they are tracking pixels.

Cookies#

One session cookie for the panel and one for the webmail, so you stay signed in. No advertising cookies, no analytics, no third-party scripts.

Your data, your call#

Write to [email protected] and you can:

Requests are answered within 30 days. Verifying that you are who you say you are is part of that, and for an email account the bar is deliberately high.

Depending on where you live you may have additional statutory rights — under the GDPR or the CCPA, for example. Those rights apply regardless of what this page says, and exercising them starts at the same address.

Changes#

Material changes will be announced by email to your account address before they take effect. The date at the top of this page is the last revision.
