LTmail is a modern email service. Keep it simple with a single mailbox, or invoke optional features like advanced filtering and sub-addresses to make your email as sophisticated as it needs to be.
Ironically, getting an account requires sending us an email: contact email@example.com if you would like to use the service.
A rich mailbox
- Sub-addressing — by adding "+" and anything you like to your email address, you gain unlimited alternate addresses that all reach you, e.g. "firstname.lastname@example.org".
- Easy mail filtering — with the Sieve filter language, and easy-to-use graphical management of filters through LT0 Webmail (and managesieve behind the scenes), you can customise how incoming emails are processed to your exact needs. You can filter on anything, for example on the sub-address used to contact you.
- Webmail access — all you need to use your email account is a web browser. Built on the popular Roundcube software (like Hermes Webmail), LT0 Webmail uses TLSv1.2 encryption to let you access your inbox securely and easily from anywhere on the internet.
- Encrypted IMAP and SMTP access — standards-compliant and (transport-)encrypted protocols only: we don't let our users send or access their emails insecurely.
- SPF, DKIM signing and good sender reputation — this is a small email service, but we sit behind the sender reputation of our large mail relay provider, Mythic Beasts. We also employ industry-standard methods for mail authentication — like a sensible SPF policy, and DKIM signing by default — to avoid your mail going to spam.
- Spam scoring and filtering — every message coming into our system is scanned for spam. Messages that are too spammy are rejected before they even reach your inbox. The ones that do get a comprehensive spam score and scanning report inserted into their message headers, so that you can do your own filtering if you choose.
- Autoconfiguration — if you're using your own mail client, then modern mail clients will auto-detect the
right settings when you enter your
@lt0.ukaddress in the "Add account" (or equivalent) screen, meaning that you don't have to put the settings in yourself. If not, ask me directly for instructions.
- Battle-tested software stack — our mail server runs on stable and trusted free and open-source software:
- Debian Linux 9 aka 'stretch', a well-supported and widely-used server operating system.
- Exim 4: a mail transfer agent developed at the University of Cambridge, and over 20 years later still in use as the bedrock of their central email service.
- PostgreSQL database system: our central management database means that changes to your account apply instantly — no waiting around for them to take effect. (This comes into its own when you add the 'bring your own domain' feature set.)
- Dovecot IMAP server: for mailbox management, filtering and IMAP access.
Bring your own domain
If you own a domain and want to have email addresses on it, I can host it for you — and you can get all the above features as
standard. The service is identical to that received by
You'll also get access to these additional features:
- Aliases — have your users reachable at multiple addresses, e.g. at
email@example.com also at a more friendly and memorable address like
Homer.Simpson@example.com, or a role-based address like
- Forwarding addresses — if you like your existing mailbox, but you want a new address on a new domain.
- Group addresses — have a single address that reaches multiple people in your domain. You can build a complex hierarchy: groups can be part of other groups, and our mail system will automatically prevent a loop if you set two groups to deliver to each other. (NB: this feature is not intended for large mailing lists.)
Coming soon: a web interface to let you manage all these features. For the time being, changes are done manually on request by me.
Authenticated SMTP relay service
For systems that don't need mailboxes (e.g. a server), but just need to send email, we have a mail sending service that isn't tied to a mailbox, but still offers all the relevant features above (e.g. DKIM signing).
This is ideal for servers located in restricted network environments where port 25 is blocked — you can get a username and password for your machines to use our secure relay service instead.
Like all communications with our mail system, the relay service enforces TLS encryption, and sensible rate-limiting is applied to ensure that no one relay user can go mad and abuse the service.
