Hi All,

I am new to mail servers, actually i have configured a domain (eg,. abc.com) in iredmail locally and there is a domain called (xyz.com) hosted in google mail, so the problem is , when ever user of abc.com  domain are sending the mail to xyz.com domain , the iredmail server is sending the mail to google mail on port 25, and because of this my public IP is always getting listed in spamhaus XBL.

And the recommendation of spamhaus for getting rid of this issue, is to send the mail to a  secure smtp on port (467 or 587) instead of smtp on port 25.

so how & where  should i configure the iredmail to use secure smtp ports (467 or 587) for sending the mail, instead of smtp on port 25

pls reply...

Thanks..
Ashraf
