Hi, today my mail server suddenly cannot send mail anymore. When I check queue: Code: 123ABCDE 8751 Mon May 25 15:50:06 [email protected] (connect to alt4.gmail-smtp-in.l.google.com[22.214.171.124]:25: Connection timed out) [email protected] I guess my provider (VULTR) may blocked Port 25 so my questions: 1. At my Outlook I set smtp port to 465 and use SSL (and it worked before today) , why on mailq status it still use port 25 ? Is it because port 465 is used for my pc connection to my server only ? And the server always use port 25 to send mail ? 2. I use Postscreen, is it possible to use other port than 25 ?
