I suspect my mailman setup is stable and OK but a new problem has
developed and can't resolve it...
Mailman 2.1.3 running with sendmail on a raq4
mailman domain is emisnug.org.uk raq is raq****.uk2net.com
ISP is uk2.net
The list is running fine, mail to most people working OK to and fro etc
The problem exists for those people who use uk2net.net (i.e. the same
people the raq is hosted with for mail forwarding etc They can post to
the list but not recieve anything
The transcript of the bounce messages are as follows
The original message was received at Fri, 17 Sep 2004 19:40:57 +0100
from localhost [127.0.0.1]
----- The following addresses had permanent fatal errors -----
<complists at domain1.com>
<emislist at domain2.com>
----- Transcript of session follows -----
<complists at domain1.com>... Deferred: Name server: ultra25.uk2net.net.:
host name lookup failure
<emislist at domain2.com>... Deferred: Name server: ultra19.uk2net.net.:
host name lookup failure
Message could not be delivered for 5 days
Message will be deleted from queue
Now that tells me that the problem is with uk2net.net and thier own MX
host names wont resolve
dig gives

the ISP resolutely refuses to answer the phone etc! but what can I do in
