*	process(): Michael Yount writes to describe the handling of error code	bwarsaw	2000-04-03	1	-1/+10
\| \| \| \| \| \| \| \| \| \| \| \|	552, as described in draft-ietf-drums-smtpupd-11.txt: [RFC-821] incorrectly listed the error where an SMTP server exhausts its implementation limit on the number of RCPT commands ("too many recipients") as having reply code 552. The correct reply code for this condition is 452. Clients SHOULD treat a 552 code in this case as a temporary, rather than permanent failure so the logic below works. Handle code 552 as a temporary failure.
*	Implementation of file queing on total or partial delivery failures.	bwarsaw	2000-03-28	1	-7/+59
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	Specifically, process(): move smptlib.SMTP() into the try/except so that socket.errors on the connection can be flagged and dealt with as total delivery failures. Better error logging. If the connection goes through but smtplib throws an SMTPRecipientsRefused exception, then Only persistent transient failures are queued, i.e. those with error code < 500. For failed recipients with codes >= 500, these are permanent failures and we do a bounce registration instead. queue_message(): handles all the actual queuing of files for future re-delivery attempts. Two files per message are written to $prefix/qfiles: one is a .txt containing the full text of the message, the other is a .db file containing a marshal of this information: listname - Python string naming the list for delivery recips - Python list of addr strings attepts - number of total delivery attempts for this queued message last_recip_count - number of recips the last time this delivery was re-tried (not sure how useful that will be). The base name of the two files is the SHA hexdigest hash of the message text.

\| \| \| \| \| \|	Also, if we get refused recipients but the error code is >= 500, do some logging. As Harald points out, we really need to handle non-permanent failures better.

	it queue messages. It registers bounces only for SMTP error codes >= 500, although errors never seem to occur with sendmail when not doing DSN -- probably because such deliveries are asynchronous.
