mail problem

[joximu]

we speak about the port 25 on the target server, don't we?
eg. your server wants to send a mail to gmx, it connects to port 25 on mx[01].gmx.net...

And theese connections are dropped by your provider?

Then you cannot do anything - you need a smarhost. Because gmx does not listen on port 26 or 2525 or whatever... except maybe port 465 if you use a secured protocol (smtps) - but not all mailserver can handle this.

OR:
or are the connections dropped which *come from* port 25? then you can change to a different.
