Development Status

SMTPD + IMAPD + POP3 is currently development phase.

TODO

Building from Source

You will need a functioning [Go installation][Golang] for this to work.

Grab the Smtpd source code and compile the daemon:

go get -v github.com/shidec/smtpd

Edit etc/mail.conf and tailor to your environment. Launch the daemon:

$GOPATH/bin/smtpd -config=$GOPATH/src/github.com/shidec/smtpd/etc/mail.conf

By default the SMTP server will be listening port 25, IMAP server will be listening port 143 and the web interface will be available at [domain:10025]

This will place smtpd in the background and continue running

/usr/bin/nohup /home/shidec/smtpd -config=/home/shidec/mail.conf -logfile=smtpd.log 2>&1 &

You may also put another process to watch your smtpd process and re-start it if something goes wrong.
