I want port 110/25 enabled instead of using SSL/TLS setup also how do I turn off that stupid greylisting?

Is support going to help with this issue?

Note that my installation is CentOS 6.4... so paths may differ for Ubuntu 12.04

1) Greylist: edit /etc/policyd.conf and set GREYLISTING=0 instead of 1
(it should be /etc/policyd/policyd.conf on Ubuntu ?)

2) turn off mandatory Dovecot SSL: edit /etc/dovecot/dovecot.conf and modify the lines as follows:
from 'ssl=required' and 'disable_plaintext_auth = yes' to:

ssl = yes
disable_plaintext_auth = no

3) turn off SMTP mandatory encryption: edit /etc/postfix/master.cf and towards the bottom of the file comment the line in the submission section:

-o smtpd_tls_security_level=encrypt

Hope it helps
