This issue also happened when the timeout setting was set at 10 minutes. greg ___ spamdyke-users mailing list spamdyke-users@spamdyke.org http://www.spamdyke.org/mailman/listinfo/spamdyke-users

It's: spamdyke - qmail-smtp - simscan - spamassassin but any bounces due to virus detection never get logged by spamdyke as an attempted connection from what I can tell, All smtp sessions are logged by spamdyke ttbomk. I believe that rejections from spamassassin/simscan show as DENIED_OTHER. Technically these are rejections, not bounces. Bounces are messages created by a mail server after having accepted an email. In the case of spamdyke rejections, messages are never accepted so there is never a bounce coming from spamdyke. The bounce would come from the sending server back to the user. and spam filtering is done after spamdyke hands off the email to qmail, so I'm not sure the time setting of timeout is affecting this. This issue also happened when the timeout setting was set at 10 minutes. This would seem to indicate that the sending server is timing out, and not spamdyke. You should be aware that the smtp session remains active/open while the message is scanned. spamdyke isn't finished with a message until it's been processed by simscan and spamassassin. This the period during which the sending server *might* be timing out, which would be why the spamdyke timeout setting is having no effect. -- -Eric 'shubes' ___ spamdyke-users mailing list spamdyke-users@spamdyke.org http://www.spamdyke.org/mailman/listinfo/spamdyke-users
[spamdyke-users] graylisting and attachment failures
Hello, Has anybody experienced issues when graylisting a domain and timeouts with attachments (PDF files in my case) Here is the scenario, Remote users sends an email to a local domain user with a pdf attachment The graylisting kicks in (normal) After the initial graylist time, the user is allowed, but the email times out. I've seen this before from multiple remote sources using qmail and sendmail servers. This happens with and without tls, so I'm not sure it's a tls issue, though I may be wrong. The log seems to indicate the connection is allowed, and the timestamp on the timeout log entry is exactly the number of seconds of the idle-timeout setting. Not sure if the communication is breaking down or what. Any ideas or experiences? best greg ___ spamdyke-users mailing list spamdyke-users@spamdyke.org http://www.spamdyke.org/mailman/listinfo/spamdyke-users
