x-mailer: Synapse - Delphi & Kylix TCP/IP library by Lukas Gebauer

The same bulk email program used in the "Joe job" attacks against our website (2003-12-16, 2003-12-19 and 2004-02-27 ) was also used in a few spams sent to our mailboxes in November and December. Spam #5 (2003-11-16) was sent via Comcast, the same provider used in the second "Joe job" against us. It claims to be from NASA, the spammer tries to mislead the recipients about the sender of the mail.

The "Mailblocks-Newsletter" (2004-02-20) looks like another "Joe job" against an anti-spam ressource. Several people have added mailblocks.com to their blacklists because they were led to believe the spam originated from the company.

Please note: According to Lukas Gebauer (who lives in Prague, CZ) he is not the author of this spamware. He only wrote a TCP/IP library which was used by whoever wrote this bulk email program.

The oldest "Synapse"-Spam we've come across was reported on a website on 2003-10-28. The bogus HELO-string in the header lays a false trace towards a shawcable.net host, as does the HELO-string in Spam #2 listed above.
