I propose to start diagnostic with: 1. exim -bt xxxxxxx...@yahoo.com 2. exim -brt xxxxxxx...@yahoo.com 3. exim_dumpdb /var/spool/exim retry | grep -A1 yahoo.com (put rial path to your exim's spool dir here) 4. exim -d-all+retry+route \ -f boun...@cathouseonthekings.com -i xxxxxxx...@yahoo.com \ < /path/to/test.file Maybe "exim_fixdb /var/spool/exim retry" or complete removal of retry db helps, but you have better to save a copy of retry db for investigation. -- Eugene Berdnikov -- ## subscription configuration (requires account): ## https://lists.exim.org/mailman3/postorius/lists/exim-users.lists.exim.org/ ## unsubscribe (doesn't require an account): ## exim-users-unsubscr...@lists.exim.org ## Exim details at http://www.exim.org/ ## Please use the Wiki with this list - http://wiki.exim.org/
