 Topic: Bounced messages to list problemPosted: 03 December 2004 at 4:46am |

Today we experienced the following problem. a mailadress in a list was wrong and generated a error from a receiving server. The error was send to the list and of course again to the wrong mailadres. Result a new error and this resulted in a loop. mail>list>error>list>error>and so on... After several hunderd (rather large) errormails the mailboxes were flooded and people started to call the helpdesk. We stopped the list, corrected the wrong mailadres and the problem was solved. I am not sure if the logsat filter should have intervened, but it definitly would be a nice feature if it did. any thoughts?

It should be easy enough to detect mail loops, but perhaps Logsat can add an option for "max mail hops" ... generally, most destinations should be 1 hop away, 2-5 normal, 6+ might be on the high side. I haven't reviewed the headers of most email enough to know what is or is not normal so those numbers might be off a little, but it's just an idea that might be able to help with detecting mail loops, and preventing those spam messages that are routed and routed and routed to hide the originator. |

Ed,SpamFilter has some loop detection functionality in that it will stop accepting emails if they contain more than 100 "Received:" headers. I'm not sure if this would have applied in your case though.Roberto F.

No, not really i guess. Every error is in fact a "new" mail so for spamfilter nothing special. But is there a possibility for logsat to deny the same mails if they are the same:.. content, from, server and so on...??? Receiving several hunderd exacly the same mails should ring some bells... |

It's not that simple... To implement what you ask, the content of any email that comes in would have to be stored so that new mails can be compared against it to see if they are the same. Any new email would have to be compared with possibly several thousands of emails to see if theu are repeats, and that would take a huge impact on performance.The real solution to avoid this and any future problems is to configure any autoresponder with a null mail from address so that this will prevent bounce messages to be created and prevent loops.Roberto F.
