[TriLUG] Bizarre email attachment problem

[Sean Leinart]

Greetings.
I am having a strange email issue. The mailserver is running postfix, clamd, and spamd. If one particlar outside domain sends an email with no attachment(s), the email reaches the inside recipient just fine. If there is an attachment, the message never reaches the inside recipient. Though the same email reaches a RR account fine. If the email is either forwarded from the RR account, or recomposed and the same attachments added, it reaches the inside recipient fine. I have checked the various associated logs / quarantines and nothing is providing and evidence. Anyone have any ideas? Thanks.
