When a message is sent to our postfix MX it seems to be stripping the recipients down to 8. We have been running postfix for many years and have never had anyone complain about this but I have confirmed the issue and cannot figure out the cause.
If I send mail directly to our mailbox application (smarter mail) it does not strip the recipients, and other recipients in the e-mail who are deliver to hosts like aol.com and gmail have the full recipient list in tact. The only relevant option I can find in postfix is: default_destination_recipient_limit = 50 Which seems fine. I thought it may have been a max character limit in the to field or something because 1 e-mail I received had 8 emails addresses and then the first few characters of the 9th e-mail -- but I have only seen this once. Can anyone offer any ideas? I have exhausted my knowledge PS - I realize users should probably be using some sort of distribution list for emails to 8 people but what am I to do about outside users doing that? And other mail hosts receive these messages correctly.
