Server is connecting with outside clients with success. Autentication with success. Sending emails with success.

The problem lies in the receiving. The e-mails arive to the machine but I guess they aren't getting sorted out.

Error in all received emails:

host mail.example.com[private/dovecot-lmtp] said: 451 4.3.0 Temporary internal error (in reply to end of DATA command)

I looked around dovecot config files but I couldn't find the problem.

Where should I look at to fix this issue? What config files from dovecot can I link here for you guys to see?

Enable logs on /etc/dovecot/conf.d/10-logging.conf with something like this

log_path = /var/log/dovecot.log

Then set its permissions

#chown vmail:dovecot /var/log/dovecot.log
#chmod 660 /var/log/dovecot.log

In my case logs were giving out this error:

Error: mkdir(/var/mail/vhosts/mydomain.com/jc/) failed: Permission denied

I created manually the jc directory and have it permissions and ownership.

Then I got this error on logs:

we're not in group 12(mail), dir owned by 0:12 mode=0775)

I solved the issue with:

#chown vmail /var/mail/vhosts/mydomain.com

and got that sweet:

saved mail to INBOX
