Re: [iMS] Retrying POST email

[Michelle Davis]

For the purposes of the post server I think that would be plenty really. Exponential backoff would always be nicer but I appreciate this is much more difficult to code.

Basically the problem we are trying to address is like this:

The post server is used to handle bulk tokenised emails to large mailing lists (5000+ people). Sometimes these people have flaky mail servers that don't respond all the time, and some of them just have plain broken email addresses. The membership changes rapidly, so every mail contains a number of completely dud email addresses. When the post server sends them, it sometimes fails the flaky servers (and retries later) and fails the dud ones. We want the initial retry time short because the flaky mail servers often reply on the second attempt, and if they don't respond for another hour or so, really that is the email user's lookout, but we don't want the system to keep trying all the truly dud ones every 5 minutes for 24 hours as this is plainly too much.

So I think the ability to set the inital retry interval and then the subsequent retry interval would be great.

Michelle

Would a setting for additional retry time be sufficient?  For example:
 
retry time = 5
additional retry time = 25
 
First retry occurs in 5 minutes.  Each additional retry occurs 30 minutes apart.
 
What do you think?
