My ISPConfog 3.0.3.3 was working just fine on earlier location (after great help of you guys), but now on new location & ISP and router (Buffalo ADSL) I have ended up trouble on mail-server. - All ISPConfig servicies green / running w/o problems (as I use them) - Fetchmail OK (from [email protected] to [email protected]) - Sending mail with roundcube [email protected] => [email protected] OK - Sending mail with roundcube [email protected] => [email protected] OK - receiving from other email to [email protected] gives trouble (copied from email delayed alarm) Code: <[email protected]>: connect to example.com[83.zzz.yyy.zz]:25: Connection timed out As I have 2 routers in my system, I have made server1 as DMZ in Buffalo. Also portscan shows that needed ports on example.com are open (21, 22,) 25 (, 53 etc.). Also individual port-forward sis not change situation better. What to check next - thanks for advice already now.
Port 25 seems to be closed on ISP side Seems that after more detailö check, on ISP-side port 25 is closed (all others open). Last time I scanned only locally I have contacted them and ask for the same (as all should be open).
