Found that some sites, in my case Adope have ip range that is routed back into my lan. Resolved this by adding statick route in my routing table. Maby do trace route to mail server and see if traffick is routed correct.

This was happening to me, I had a layer 7 protocol filter set with a string of “^get.+announce.” without the quotes and a IP Firewall Mangle Rule for chain:prerouting with a jump to my torrent_traffic rule. Apparently part of the request for the yahoo main page to yimg.com (yahoo’s image server for their main page) matched that layer 7 regex and was being sent to my torrent blackhole. I have examined the cleartext http from the request to yahoo and cannot determine why that regex was being matched. If anyone else has any insight into this issue, i’m all ears. To correct the issue, I have disabled the Mangle rule that referenced this Layer 7 regex string, however this is a bandaid, not a permanant solution, as I need that rule to keep my network sane!!!

so, first 10KiB of page doesn’t contain ‘announce’ string?..
