The connection was dropped due to an SMTP protocol event sink + others (AVG)
Posted on 2009-05-12
Ok, ive got problems on 2x SBS 2003 machines/ setups with this occuring on both in ESM / Queues, we either get the above error, or other events like messages stuck in the queues and not going anywhere.
i can 'iisreset' and things start flowing again and ive put it down to AVG being the culprit (8.5 SBS INT Sec) with its new exchange sided spam solution.
AVG have no idea what the issue is and im really at a loss (other than removing AVG from the server), ive uninstalled the AVG Spam software, but have still got an AVG event sink, which i cant remove or disable (can someone give me the correct string)
Event: SMTP Protocol OnInboundCommand
Name: SMTP AVG 8 AS Filter
rule = _EOD
priority = 12000
C:\>cscript smtpreg.vbs /disable 1 onarrival "SMTP AVG 8 AS Filter"
