LMTP is a small modification of SMTP with a per-recipient response code - but I'm not sure what it's intended for. It isn't used on the internet. It's sometimes used as IPC within a mail server.
- baudehlo 4mo agoLMTP is for delivering to an IMAP (or JMAP) mailbox, generally. We also have a plugin for that. But it has certain flaws for exposing it to the internet (I just forget what they are right now).
- inigyou 4mo agoThere's no such thing as an IMAP mailbox. Mail receiving is split down the middle. Your SMTP server stores the email in a folder and your IMAP server provides access to that folder.
- baudehlo 4mo agoThat's not how things work at all. For context, I'm the author of Haraka, a popular open source SMTP server. SMTP servers don't necessarily store anything. They have two responsibilities: Receiving and delivering email. What they do with the emails they receive is up to the configuration.
