Auto unsubscription

Hello all,

last friday my account for mailinglists got unsubscribed from all PG
lists. In my mailserver log i found the last entry at 5am
(my timezone: CET). After that no more mails reached my account.
Right now i subscribed myself to all lists again, in the case that
there is just a mailserver problem, that should be not possible but the
mailinglist software should tell me, that i'm already subscribed.

For the -announce list i'm subscribed with two account, my regular mail
account and the one i use for mailinglists. The first one is still
subscribed, both accounts end on the same mailserver.

So i would like to know, what happened and why i'm automatically
unsubscribed from all lists. Any chance to find this out?

Thanks & kind regards
