Hi all, As till now no one responded, I'll try again to ask. I'm using sendmail and fetchmail. I have given sendmail some adresses to filter. I have a dial up connection to the internet. Now I receive some mails from a spammer and unfortunatly something goes wrong, when filtering. Here are the logs: fetchmail: forwarding to localhost fetchmail: SMTP> MAIL FROM:<[EMAIL PROTECTED]> BODY=8BITM IME SIZE=29045 fetchmail: SMTP< 553 <[EMAIL PROTECTED]>... User unknown fetchmail: SMTP error: 553 <[EMAIL PROTECTED]>... User unknown fetchmail: SMTP> RSET fetchmail: SMTP< 250 Reset state fetchmail: SMTP< 220 localhost.localdomain ESMTP Sendmail 8.9.3/8.8.7; Tue, 7 Ma r 2000 23:12:05 +0100 fetchmail: SMTP> HELO localhost fetchmail: SMTP< 250 localhost.localdomain Hello IDENT:[EMAIL PROTECTED] n [127.0.0.1], pleased to meet you fetchmail: SMTP> MAIL FROM:<FETCHMAIL-DAEMON@localhost> fetchmail: SMTP< 250 <FETCHMAIL-DAEMON@localhost>...

(EOM) fetchmail: SMTP< 250 XAA00863 Message accepted for delivery fetchmail: SMTP> QUIT fetchmail: SMTP< 221 localhost.localdomain closing connection ........fetchmail: socket error while fetching from pop3.myprovider.de fetchmail: Query status=2 Now can anybody help? As much as I understand it, my sendmail accepts the mail and wants to bounce it, I suppose that's O.K. but then I suppose with the QUIT command something goes wrong. The mail is not deleted from the pop server of my provider and all previous mails are not deleted, too. So I keep getting always the same mails from my provider's server. Why do I get a socket error? This mail somehow blocks my mailbox on my provider's server. How to solve this problem? BTW I've read the man page for fetchmail, but I do not understand the antispam part that well. Is there any additional info with some examples on how to block spam wiht fetchmail. TIA Andreas -- To unsubscribe: mail [EMAIL PROTECTED] with "unsubscribe" as the Subject.
