When ColdFusion mail fails to deliver it will sit in the undelivr folder forever unless someone copies it back to the spool folder for another try. Mail that is actually invalid will just keep ending up back in the undelivr folder forever unless someone deletes it.

I am quite surprised Adobe have still not addressed this, especially considering they added a new feature to CF9 allowing you to view and manually respool failed mail, which is ok if you only have a few emails, but as it only displays like like 10 emails at a time, it is useless on a server that processes hundreds of thousands of emails per day.

Up till now I used a little VB script and a windows scheduled task to handle this, but I decided it was time for a CF solution that I could easily just plugin into the cfadmin.

So here it is, a custom extension for your ColdFusion administrator which allows you to specify how often you want to respool your undelivered mail and how long you want to keep trying for, after the retry limit is reached the undelivered mail will just get deleted.

FYI Railo retries sending mails by default.

readme.txt file in the download contains installation instructions.

I may also add the option to send a failure notice to the sender for failed mails that get deleted.

If you want the ability to manually view/edit failed mail and send back to the spool then try Ray Camdens Spoolmail.
