ColdFusion mail queue stops processing

Question

Our CF server occasionally stops processing mail. This is problematic, as many of our clients depend on it.

We found suggestions online that mention zero-byte fil

Answer 1

I have the same problem sometimes and it isn't due to a zero byte file though that problem did crop up in the past. It seems like one or two files (the oldest ones in the folder) will keep the queue from processing. What I do is move all of the messages to a holding folder, restart the mail queue and copy the messages back in a chunk at a time in reverse chronological order, wait for them to go out and move some more over. The messages which were holding up the queue are put in a separate folder to be examined latter.

You can probably programmatically do this by stopping the queue, moving the oldest file to another folder, then start the mail queue and see if sending begins successfully by checking folder file counts and dates. If removing the oldest file doesn't work, repeat the previous process until all of the offending mail files are moved and sending continues successfully.

I hope the helps.
