I tailed the maillog and then tried to connect. I am getting smtpd service unavailable. I'm not sure what to do to get it running.

Hi techguyal,

pls. restart the depending service with for example:

Code: 
service psa-pc-remote restart

service postfix restart

service dovecot restart

If you use as well "Premium Outgoing Antispam", pls. don't forget to restart it with for example:
Code: 
/etc/init.d/ctasd_initd start
/etc/init.d/ctmilter_initd start


Pls. check, that no firewall or ( possible ) Fail2Ban - entries block the connections and make sure, that IF you use Fail2Ban, that localhost ( 127.0.0.1/8 ) and each of your server IPs are whitelisted.


If you still experience issues/errors/problems, pls. don't hesitate to use the Plesk Repair Utility with for example:
Code: 
plesk repair mail -y -v
