>call their help desk and ask them?
Coditel did block port 25 for all outgoing mail since Monday for my IP
address! I tried 'telnet servername 25' for a half a dozen SMTP servers
and none of them worked! My mail provider (german provider Puretec)
offers the alternative port 587 (RFC conformant) for SMTP. So I switched
to this port and everything worked again! The Putetec FAQ also tells the
reason why they offer the alternative port 587: Blocking port 25 seems
to be very popular especially at universities according the Puretec FAQ.
I consulted the Coditel FAQ to see if they mention this. Nothing. So I
telephoned to the helpline. I told them that I didn't appreciate ISPs
who block important ports without mentioning it in their FAQ and that
there are many people who own their own E-Mail addresses and who don't
want to use a coditel address. The helpdesk told me that they will
forward my complaint to their administrators!
This evening I checked again. Port 25 is open again (at least for me)
