In that case, I would contact your ISP and let them know what happened. Include the original email and headers that they provided and annotate it to point out the places in the headers that prove your point. (my server received it here, it was rejected due to invalid address here, it was received by the complainer here, it was forwarded to spamcop here, etc.) I have had to do this before.
If you prove to them that you didn't send spam then they should accept your explanation. If not, then they are just being unreasonable. Your mail server was simply acting as it should. It may also cause them to review these types of complaints before sending them on to their customers with such threatening wording, although this was probably forwarded to you via some sort of automated system so I wouldn't count on them changing their processes. This is just another way we as mail admins have to defend our networks against spammers. The ISP *SHOULD* do the work of verifying the authenticity of the complaint before they contact their customer about it, but many of them foist that workload off on us. FWIW, I was successful in getting my ISP to review complaints before forwarding them to me, but I don't know how successful you will be with yours. -Dan Horne To Unsubscribe: http://www.ipswitch.com/support/mailing-lists.html List Archive: http://www.mail-archive.com/imail_forum%40list.ipswitch.com/ Knowledge Base/FAQ: http://www.ipswitch.com/support/IMail/
