Hi,
I'm trying to migrate to iRedMail easily without reconfiguring dosens of mail clients. The problem is that mail clients are setten up to login on POP3/SMTP with login ("username"). But sending/receiving with iRedMail server succeeds only if "username@domain.com" is specified as login for POP3/SMTP. Is it possible to tune up something on server side?
The only message I can see in mail client is "ERR authentication failed" after "POP3 server connected successfully" while receiving and "Helo command rejected: need fully-qualified domain name".
Server's log has (/var/mail.log):
May 19 17:16:09 mx postfix/smtpd[4380]: warning: hostname 1-2-3-4.provider.com does not resolve to address 1.2.3.4: Name or service not known
May 19 17:16:09 mx postfix/smtpd[4380]: connect from unknown[1.2.3.4]

May 19 17:16:17 mx postfix/smtpd[4380]: disconnect from unknown[1.2.3.4]
If I specify username@domain.com instead of username all goes smooth.
Thanks in advance
