Hello Guys

I was checking with:
                                  tail /var/log/dovecot.log
                                  tail -f /var/log/mail.log
                                  tail -f /var/log/mail.err
                                  tail -n 50 /var/log/syslog

also I checked the ports:
                                  nmap -sS -p 20-2550 localhost

Everything looks fine, I don't know what else to do, I used iRedmail with ubuntu 15.10, but it does not work too, that's why now I installed ubuntu 14.04.

I will appreciate any advice about it
