I have a Linux box which scans my mails with fetchmail. Recently I started to receive
SMTP< 552 Header line is ridiculously overlong
error messages. I have checked out the mails and found out that the sender is trying to send to a list just by adding them up at the to line, all at once (about 2000).
I can receive the same mail via outlook express directly from the pop server, but if I fetch it and submit to my mailserver (Exim version 2.05) I get error. Is this an already corrected issue?
