[fetchmail-users] Re: Fetchmail socket error.

[Ernst V. <e.v...@vi...>]

Hello everyone.

Thanks again for the suggestions.

FreeBSD on the host is running dovecot 1.0.beta3. This is the latest 
release available via the ports collection of FreeBSD. I deleted the 
index files, dovecot rebuilded them and the error still remains.

I asked the administrator to install ethereal, this will be done in a 
short while. For some reason there are huge dependencies of graphical 
packages. So i'm hoping I can provide additional information concerning 
the socket error.

Also I will install a different packet filter on this machine. For 
testing purposes I can disable the current packet filter, but the 
administrator is not very happy with that on the long term. :-). So I 
will try IPF. Playing with the firewall is dangerous, considering the 
host machine is located about 100km from my current location and is not 
fulltime accessable.

Thank again for all the effort everyone. I will post additional 
information concerning the ethereal dump soon.

Kind regards, Ernst
