[Mailman-Users] No subscription is made despite confirmation

[Henrik Rasmussen]

One of my list administrators have celled me regarding some users not being subscribed to a list. Mailman have sent the users in question a confirmation ticket, and the subscribe log shows that the users have been put in pending mode.
 
Jan 31 13:09:33 2008 (2223) listname: pending me at privacy.net <mailto:me at privacy.net>   me at privacy.net <mailto:me at privacy.net> 
 
When the users returned the mail, Mailman issued a New command
 
Jan 31 13:11:29 2008 (2223) listname: new "me at privacy.net <mailto:me at privacy.net> " <>, via email confirmation

 
but still the users wasn't subscribed (list_members listname still did not show the user as member of the list). A few days later one of the users retried subscribing, and the same happened. The log does not show any signs that the user have tried unsubscribing (deleted).
 
According to the error log at the particular time, Mailman seems to have failed subscribing the user.
