Mailman's 'smtp' and 'smtp-failure' logs will tell you about delivery to the outgoing smtp server. If there is an entry in the 'smtp' log of the form '%(msg_message-id)s smtp to %(listname)s for %(#recips)d recips, completed in %(time).3f seconds' and no entry in the 'smtp-failure' log, Mailman has successfully transferred the message to the outgoing MTA. If bounces are subsequently returned, they will be noted in the 'bounce' log if bounce processing is enabled. As far as how Mailman delivers, this depends on a number of things. The basic controls are Defaults.py/mm_cfg.py options SMTP_MAX_RCPTS (default 500) and SMTP_MAX_SESSIONS_PER_CONNECTION (default 0). These defaults say messages should be delivered to the MTA in chunks with a maximum of 500 recipients per chunk and as many chunks as necessary with one connect to the server. SMTP_MAX_RCPTS adjusts the chunk size, and if SMTP_MAX_SESSIONS_PER_CONNECTION is > 0, after that many chunks are sent, Mailman will close the SMTP connection and re-open it for the next chunk. VERP and personalization will reduce the chunk size to 1 - i.e., each recipient will be sent to individually. In any case, there will be only one 'smtp' log entry for a successful message send indicating the total #recips and time, regardless of how many chunks are sent. See the Defaults.py/mm_cfg.py settings for VERP_DELIVERY_INTERVAL and OWNERS_CAN_ENABLE_PERSONALIZATION and the list's personalize setting if OWNERS_CAN_ENABLE_PERSONALIZATION = Yes. As far as resolving the issue, the problem seems to be out of Mailman's hands based on what you say about the post and smtp logs. You may be able to work around the issue by mm_cfg.py settings like for example SMTP_MAX_RCPTS = 5 SMTP_MAX_SESSIONS_PER_CONNECTION = 1 but this may not help depending on what the actual problem is. -- Mark Sapiro <[EMAIL PROTECTED]> The highway is for gamblers, San Francisco Bay Area, California better use your sense - B.
