[HowTo] Replace courier with dovecot

[dexter1983]

myhostname as srv.domain.tld or just srv , but i think only srv because srv.domain.tld is fqdn

---

in /etc/postfix/main.cf I don't find any lines with postgrey, maibe because of that ther is a problem with it.

---

I finaly manage to login with all user in webmail and roundcube, but the messege don't send

This is in mail.log
, relay=dovecot, delay=0.17, delays=0.05/0.03/0/0.1, dsn=5.3.0, status=bounced (command line usage error. Command output: Fatal: Unknown argument: -s Usage: deliver [-c <config file>] [-d <destination user>] [-m <mailbox>] [-n] [-e] [-f <envelope sender>] )

An send to hotmail and yahoo:

Feb 18 11:40:54 web postfix/smtp[3076]: connect to mx4.hotmail.com[65.55.37.120]:25: Connection timed out
Feb 18 11:41:04 web postfix/smtp[3077]: connect to c.mx.mail.yahoo.com[206.190.54.127]:25: Connection timed out

Maybe to yahoo and hotmail don't work because I have an dynamic ip on wan or maibe because I am behing a nat router?!

I will do post fowarding for mail posts to see if I receive any messages from yahoo.
