[Mailman-Users] subscription request sent twice

[Zbigniew Szalbot]

Hello,

Sorry for yet another post. I have been googling to find an answer but 
have not been successful.

It seems that on my new server Mailman will sent each subscription 
request twice. Regular posts, information that someone is already on 
list are not sent twice. Only subscription requests. For example, these 
are the two I got while testing:

confirm 0be9992ac451e22a969a29bbc5f7c5a4d2a9c30d
confirm 3a90201f480e72b58bc804f650f67a84a18bc284

and Mailman's subscribe log shows:
Apr 26 10:53:54 2008 (76585) eu.ppl: pending Zbigniew Szalbot 
<zszalbot at yahoo.com>  zszalbot at yahoo.com
Apr 26 10:53:54 2008 (76585) eu.ppl: pending Zbigniew Szalbot 
<zszalbot at yahoo.com>  zszalbot at yahoo.com

I have analized MTA's logs and they have really been sent twice as 
separate messages although I requested subscription only once.

I am not blaming Mailman. I feel that there must be something wrong with 
my setup that this happens. I'll appreciate if someone has had the same 
experience and can suggest where to start troubleshooting it.

Thanks!
