[Zope-dev] Retry Fixes for zope.sendmail

Hi There! During the last few days I have been doing some fixes for zope.sendmail to do with the trouble we are having with it on our Zope 3 application, which actually sends a lot of emails. Problems I in the fix are: 1) Handling of SMTP error 451 etc. 2) Cleaning stale lock links out of the queue 3) Handling Server disconnection 4) Handling of connect() failure 5) A bit of a clean up QueueProcessorThread so that it complies with IMailQueueProcessor in interfaces.py Events 1, 3 and 4 are handled by waiting for 5 minutes, and then restarting processing. I would appreciate hearing from the zope.sendmail developers. Once I have the code complete I will gladly post a diff tomorrow. Best regards, Matthew Grant
