while sending an email with ~25 attachments each with two more attached documents (they're courier bounces), i got the following message:
550 Message MIME complexity exceeds the policy maximum
hard as i try, i can not find where that "policy" would be set. i have also looked in the RFCs a bit to no avail. anyone familiar with the internals could explain the why and how of it? is it a courier thing? or something required for smtp?
note that i am not trying to CHANGE it, i'm just wondering about this new error. it's also a handy information to have for my spam reporting script
It's a Courier thing. Messages are limited to 300 MIME sections. A bounce consists of three parts, actually: text/plain, report/delivery-status, and message/rfc822 (or text/rfc822-headers), and a top level of multipart/report makes it four MIME sections per bounce. With 25 of them you're up to 100 sections.
If you attached each one to another message, you have one message/rfc822 section per attachment, plus one for the multipart message type, bringing the count to 126. That still falls some ways short, but if the original messages that were bounced themselves were MIME messages with attachments, that gets added up too.
The limit on MIME section count is intended to prevent unlimited growth of data structures that parse MIME messages.
