Sendmail woes (domain resolving)

[Marc UBM Bocklet]

Hello everyone!

I'm not 100% sure if this belongs here, as it is primarily a sendmail
configuration problem. 

Sendmail blocks incoming mail delivered to it by fetchmail, if it's
unable to resolve the domain the mail is sent from. For example:

sendmail[2424]: h4RKlrp0002424: ruleset=check_mail,
arg1=<odxo9zpm3nig at loyus.com>, relay=FDO_GSD at localhost [127.0.0.1],
reject=451 4.1.8 Domain of sender address odxo9zpm3nig at loyus.com does
not resolve


I tried to add the options 

FEATURE(accept_unresolvable_domains)dnl
FEATURE(accept_unqualified_senders)dnl

to the freebsd.submit.mc and the freebsd.mc file, but it didn't work.
I'm pretty sure that I'm doing something wrong, but I'm not sure what it
is.

The reason that I want sendmail to deliver such mails is that fetchmail
will not fetch any additional messages from an account once a message
has been rejected by sendmail.


How can I get to do sendmail what I want it to do? I'm pretty sure that
I'm missing something obvious.

Bye
Marc
