[Mailman-Users] mailman-bounces error

[Andy Gao]

Hi, all:

I installed mailman2.1.6  with sendmail8.13 on fedora core3 box.

I saw in the root mail some messages like this:

 The following addresses had permanent fatal errors -----
<nui at abc.org> <nuin at genedrift.org>
    (reason: 550-Verification failed for
<mailman-bounces at localhost.localdomain>
<mailman-bounces at localhost.localdomain>)


  ----- Transcript of session follows -----
... while talking to abc.org.:

>>> DATA

<mailman-bounces at localhost.localdomain>

=============================================
I guess that is something wrong with my MTA configuration.
for other mailman related account:
mailman-request at ex.com
mailman-owner at ex.com
..
are correct with my domain name "ex.com".

Any enlightment?

Thanks.
