Re: [sqlite] Mail loop?
The problem is that somebody has a .forward or such which loops back to the list. It's probably in the alias expansion of sqlite-users which expands to a listfor which a member then expands back to sqlite-users. The mail logs may show whether it happens locally or if its a remote user. If it's a remote user you should see a log entry complaining about too many loops and it may ID the user name involved.

Re: [sqlite] Mail loop?
It's been that way since email existed. Mail loops used to cause complete havoc with the internet and mail servers. Especially local loops. People used to just kill their email servers to stop it. And out-of-office replies caused havoc with email lists when they first came out. Mail loop detection was added to many systems around 5 years ago or so to stop the problem. Unless somebody has a brilliant idea to fix email world-wide we have to suffer a bit. All it takes is this: us...@somwhere - maill...@somewhereelse - us...@somewhereelse (has a .forward to maill...@somewhereelse ). And voila! A mail loop. People who don't have considerable long-term email server experience are gleefully unaware of the history behind this. I was a network admin back in the 80's and saw this problem lots of times.

Re: [sqlite] Mail loop?
And if Peter isn't the problem you can do a binary search. With 2500 members just keep splitting the list in half and set a test email to each half. Then do it again for the half that shows the loop. 2500-1250-625-318-159-80-40-20-10-5-3-2-1 26 emails will ID the culprit (two at each level -- one should show the loop and one should not). Just put a different subject in each email so you know what you're looking at. Or...2500 emails to each person on the list..one of which should show up on this list. Michael D.
