Networks fetchmail issue... any ideas?

Ok,

This is doing my head in, i've been going round and round with this and cant see a solution.

Fetchmail refuses to download emails that the dns doesnt resolve on;

output: "fetchmail: SMTP error: 451 4.1.8 Domain of sender address bev@XXXXXXXXXXX.com does not resolve"

Right so I tried using the nodns flag in my fetchmailrc file... tried both;

"poll XXX with no dns user XXX pass XXX"

and

"poll XXX with nodns user XXX pass XXX"

Neither work.

Obviously I have replaced "information" with X's

Ideas?

 

Well being the legend that I am, I sorted it.

Recompiled sendmail with a tiny bit of modification so that it wont do its check_mail rubbish, but will still pass stuff to spamassasin.

on

 

no checkalias?

 

Nah took out the whole check_mail thing so it wont try and resolve DNS's but will still pass on to whatever else, and process the error codes correctly.
