Here is my issue, to get around my ISPs Port25 blocking I setup an alternate port for smtp.mydomain:666 (instead of the standard Port25).
So for that works fine on my iPhone. Receiving (imap) is no problem, but sending fails when I switch SSL on.Without SSL it’s fine. But I believe without SSL messages and passwords could be captured from the WiFi stream.
It seams that the iPhone has just SSL as security option.
So how do I enable postfix SSL for SMTP in Webmin?
Or is such a connection save anyway and I don’t need SSL?
There should be a few lines trailing that one you saw there, they generally begin with a “-o”. Make sure you uncomment those as well, and that you restarted Postfix using “/etc/init.d/postfix restart”.
Well, it might help to make an assessment here if you told us what error/problem exactly occurs when you try to connect to SMTPS. You say “465 is ok, 25 is blocked”, so what’s the error?
