[Mailman-Users] localhost.localdomain problem

[Mustafa Akgul]

I am  running  mailman  lists on several machines,  whixh are mostly
debian and solaris.

I have once  virtual machine which is debian also.  debian 7  with kernel
Linux listweb 2.6.32-29-pve #1 SMP Thu Apr 24 10:03:02 CEST 2014 x86_64
GNU/Linux
from dpkg -l
mailman                         1:2.1.15-1                    amd64

I have setup a list say math,  it  distrobutes  messages OK
but on moderation page  any  request to accept, deny fail  with

Firefox can't find the server at localhost.localdomain.

servername  in the URL becomes localhost.localdomain

and telnet localhost 80  and telnet localhost.localdomain 80  are OK

any ideas / suggestions
