Original GitHub issue: https://github.com/axllent/mailpit/issues/249

Is it possible to implement an IMAP or POP server in the project? So I can test the emails in my favorite client, instead of the web UI.

I know I can forward the messages to a real SMTP server, but the reason to use Mailpit is just avoid flooding my mailserver with crap 😕

Hi @oliveiraev . This has been asked already a year ago in #72 - which I declined as I had another 100 development priorities at the time. IMAP is very complicated as one deals with various states of email, folders etc (which Mailpit does not have), but POP3 might potentially be a new feature now. I'll have to think about this a bit more and do some research before saying yes or no. Please leave this with me for now.

I'll have to think about this a bit more and do some research before saying yes or no. Please leave this with me for now.

@oliveiraev This ended up being more complicated that I had anticipated because I had to write a complete POP3 server from scratch. Fortunately POP3 is one of the most simple protocols around so it wasn't that bad....

I have released this feature in v1.14.0 and the documentation can be found on the website. Please read the notes in the documentation and let me know if you have any questions, and confirm whether this works as you expected? Thanks.

@axllent So far via cli it works. Thanks so much for this project it really saved lot of headache 🤯 of setting up a whole server. When all need to do is test before production. I can test it more if you would like?

frappe@crm5-dev:~/frappe-bench$ telnet pop.in.com 1110
Trying 192.168.1.213...
Connected to pop.in.com.
Escape character is '^]'.
+OK Mailpit POP3 server
quit
+OK goodbye
Connection closed by foreign host.
