Hi,
problem is still the same, but I think I can give some more information.
I changed the number of uses for pop3 to 1 (-U 1) and now I can attach a
strace for a hanging and blocking others pop3 session. Seems like the
client is gone before pop3 could be started. Hope anyone with more
experience is so kind to have a look at this.
Many thanks,
Ingo
