To check out a slowness in emal processing, I turned on tagging for incoming email. To my surprise, the following message is appended to all incoming email from two servers (so far): __________ Information from ESET NOD32 Antivirus, version of virus signature database 2747 (20071225) __________ The message was checked by ESET NOD32 Antivirus. part000.txt - decompression could not complete (possible reasons: insufficient free memory or disk space, or a problem with temp folders) Most of the received emails are plain text (mime: text/plain) although a few HTML emails (mime: multipart/alternative). The message makes no sense. I have approx 1gb free physical memory, over 100gb free disk and temp files/folders are cleaned daily. This may be related to the slowdown. Any thoughts? Should I open a report at ESET?
