Hi Happy Courier-Users,

I'm a an of courier since many years as it offers me all the functionality I
want (smtp/pop3/imap) fully integrated and easily configured. But now I have
a problem, that is giving me a headache after googling for many hours,
looking through the sources of Courier.
I've got 2 sorts of non-deliveries coming into the system rejecting the
email coming in.

First is
421 No SMTP servers were available to authenticate sender

Second is
517-MX server mailx.telcom.net said:
517 Sender does not exist:

I think both are related and cause courier to call the originating server
back in order to verify that he knows the sender.
Is there any way to disable this? I know it would make sense to reduce spam,
but it also causes users from other (often webmail services) to be blocked
as well.

Thanks already for this great piece of software
Koen
