Ouch! Yeah, I thought I had adiquate filtering for bounced mails, but I guess not. I added some more. Good idea on the size limit, too, I'll add it. Funny, I think the whole thing was triggered by a friend's computer which he installed a new Linux install on Friday night. I had my email account on it be a test member of the sensors list a long time ago. Things starting bouncing when he brought his new install up, and other receivers' mail daemons got in the act. A mysterious spam was also hammering the list over and over at the same time, which was odd... Anyways, thanks to Mark who tracked me down and left me a couple voicemails urging me to find out what was going on. Phil Jean Delvare wrote: >Hi everyone.
