OK, here is comes: I use SuSE 7.1 with 2.4.0-4GB kernel (original
suse-kernel), MTA = postfix-20001212-4. I have a static ip-address (adsl). I
use fetchmail(fetchmail-5.6.0-5) to pop3 one account, but this isn't the
account that received this mail. The account that received the mail is one
that I pop3 from KMail (KDE 2.1.1) from my workstation. Furthermore I use
gotmail to get my mail from hotmail, it runs every 5 minutes and sends mail
to my mailbox. (on the server/gateway). To get al the mail I pop3 the
server/gateway from my workstation with KMail. On account of my configuration
on KMail: I have a filter-rule that states that every mail from a whole
domain (in To and CC) has to be transfered to a specific folder.
So the problem is I don't know to which account/email-address the mail has
been sent, but I'm pretty sure it is the account that I check manually (via

I did just that: this is everything that is in the mail :-(.
