Hello, I did a quick search in the mailing list about this issue, but didn't find anything related, so here I go:
When an email with multiple RCPT TO is sent in single SMTP session, it seems all previous recipients are logged at each new RCPT TO command. See attached spamdyke.txt log for details (I've replaced original sender/recipient names for privacy reasons). Basically if there's incoming mail from one sender to 3 recipients in single smtp session I see something like: ALLOWED from: sender to recipient-1 ALLOWED from: sender to recipient-1 ALLOWED from: sender to recipient-2 ALLOWED from: sender to recipient-1 ALLOWED from: sender to recipient-2 ALLOWED from: sender to recipient-3 Which in some extreme cases where session had 9000 recipients led to multi GB log file. Glancing quickly through sources I didn't find how this works, but I'll look again later this week when I have more time. -- Teodor Milkov | System Administrator | ICDSoft Ltd.
