Any kind / patient person offer any tips ? Still can't track this down ;
[root@mail ~]# netstat -tln | grep :465
tcp 0 0 0.0.0.0:465 0.0.0.0:* LISTEN
From another thread I read the above as the port being open and available. The server is in 'Server Mode' only and is behind an ADSL Router / Firewall. I have a nat rule to forward requests for port 465 to the server as well as a firewall filter rule that pinholes port 465. All the other rules I have setup in this way [ssh,https,imaps] are working fine. An external test using canyouseeme.org reports that port 465 is open.
I am now thinking its something I am doing [or not doing] on the mail client thats stopping this working.
I have the WAN IP address down as the incoming imap+smtp, and in advanced outgoing port as 465, incoming as 993 and both SSL boxes ticked. Just tested this again and getting error from mail client ; outgoing is being rejected with 550 relaying denied error - I am using the admin account for testing purposes.
I have 'Allow SSMPT (secure)' in the email settings of server manager.
Any help appreciated
