Since my ISP blocks port 25 I'd like to be able to configure postfix to send smtp email over port 587. Every time I try to send an email I see this in the mail.log
Oct 17 10:37:49 new-host-2 postfix/smtp: connect to aspmx.l.google.com[18.104.22.168]:25: Operation timed out
I'm assuming this is due to the fact that this doesn't work over port 25. What do I need to modify in order to get smtp to communicate over port 587? I tried using port forwarding but that wasn't working either.
Not sure but I think if I can get the mail.log to show
[22.214.171.124]:587 this would work. Any idea how to switch this?
Thanks in advance!
