Don't know if it's related, but I'm seeing a SIGNIFICANT increase in SMTP REJECTs, something to the tune of a 10- to 15-fold increase. I started seeing it simultaneously on both my primary and secondary boxes, starting around 7:AM EST yesterday (Thursday). I log RBL rejects as 'spam' so this is something different.
I'm going through the logs now, but it appears I started getting a large number of connections similar to the following: Feb 3 07:23:17 gwmail1 postfix/smtpd[27839]: connect from unknown[w.x.y.z] Feb 3 07:23:17 gwmail1 postfix/smtpd[27839]: lost connection after CONNECT from unknown[w.x.y.z] Most of them appear to resolve to residential connections...related? - GA >>> Matt Kettler <[EMAIL PROTECTED]> 2/3/2005 5:32:46 PM >>> I encountered one ISP who's legitimate mail gateway is freaking out under the load of all the proxy spam.
