This is my probleme:
I have sendmail-8.11.6-9.72.4, in Red Hat Enterprise Linux ES release 2.1 with a kernel 2.4.9-e.12smp.
And i use the SMTP authentification to relay for my users based in cyrus-sasl-1.5.24-24.
I have to servers:
The firset is the SMTP server (smtp.mydomaine.net), it used for my relay.
The 2nd is the POP server(pop.mydomaine.net), it's my reception server.
my domaine is mydomaine.net. I can send for another domaine (for exemple yahoo.com) and I can recieve.
