Your MTA is adding this header containing all the recipients in the particular SMTP transaction that delivered this message from Mailman to the MTA. You need access to the installation to do anything about this. If this is a hosted Mailman, you'll have to deal with the host. There are two ways to fix this. 1) fix the MTA, probably exim in cPanel, <http://www.exim.org/exim-html-3.20/doc/html/spec_49.html#SEC835>. 2) change Mailman to send only one recipient per transaction. This can be accomplished in multiple ways: a) If personalize is available in Non-Digest options, set it to Yes. b) add VERP_DELIVERY_INTERVAL = 1 to mm_cfg.py c) add SMTP_MAX_RCPTS = 1 to mm_cfg.py (I recommend b) -- Mark Sapiro <m...@msapiro.net> The highway is for gamblers, San Francisco Bay Area, California better use your sense - B.
