Hi Sometimes, don't know exactly when... When people receive email through our mail mta Linux Redhat AS 3.0 Taroon update 3 2.4.21-27.0.2.ELsmp (Postfix + Trend(IMSS 5.5) + SA 3.0.3 then third party mail server with attachment of about 2Mo, the attachment is "destroyed" when passed over spamassassin scan. Here is a log sample. You can see original mail size : from=<sender>, size=2295839, nrcpt=1 (queue active) to=<recipient>, relay=localhost[127.0.0.1], delay=6, status=sent (250 Ok: queued as 2353F73545) ---> Trend Filter IMSS 5.5 from=<sender>, size=2296058, nrcpt=1 (queue active) from=<sender>, size=2381, nrcpt=1 (queue active) After passing through SA, the email size is about 2381 instead of 2295839 I know that SA bypass scan of email >250ko but i think mail is "look at" just to check size and then directly forwarded to the next transport. Perhaps i'm wrong and there is no pipe is mail is >250k I've check antivirus log and the transaction went ok The result is that le recipient receive the email but with no trace of the attachment Last time, it was with a pdf file 2Mo Help would be very appreciated !
