Not necessarily. The recipient list is calculated (and it's in a hashed order, so it's not alphabetical). In delivery, it is then sorted by domain and chunked into pieces of size SMTP_MAX_RCPTS (default 500). Then, a connection is opened to the SMTP server, and the message is sent in 8 or so transactions of 500 RCPTs each, and the connection is closed. The MTA may not like 500 RCPTs per transaction in which case you need to reduce SMTP_MAX_RCPTS in mm_cfg.py. It may not like a number of large transactions on a single connection in which case you need to set SMTP_MAX_SESSIONS_PER_CONNECTION to some non-zero number in mm_cfg.py. The default setting is zero which means all chunks will be sent on a single connection. A non-zero setting (1 or 2 or so) means send that many chunks, then disconnect and reconnect befor sending that many again until done. -- Mark Sapiro <[EMAIL PROTECTED]> The highway is for gamblers, San Francisco Bay Area, California better use your sense - B.
