autoresponder not working

Hi there --

On one of our domains we used to have a mailman list called "planning@domain.com". We have deleted that list & now we want an autoresponder on the planning@domain.com address. Have set up the autoresponder, with interval 0 and takes effect immediately. It just doesn't work. Set up a legit email account planning@domain.com. Still doesn't work.

The autoresponder looks just fine. If I log into the planning@domain.com webmail the autoresponder shows there too. Emails sent to the account are showing up in the inbox, but autoresponses are not going out.

Exact setup:

character set: utf-8 (i never messed with this, it was the default)
email: planning@domain.com
from: joinus@domain.com (a real email account)
subject: your message was not posted
html: unchecked
body: Reminder: The former "planning@domain.com" discussion list has been taken down.

Please re-send your message to members@domain.com instead.

(Any questions, just reply to this message)

start: immediately
stop: never


What can I try to make this autoresponder work?

TIA!

 

Thanks for testing. I just tested on the same server where I'm having the problem, this time using an e-address that does not have a real account on the server, test-a-r@domain.com

This autoresponder works fine.

It also works if I set up a real email account for test-a-r@domain.com

So the problem with the planning@domain.com autoresponder must be that this used to be the address for a now-deleted Mailman list.

Where can I look on the server to clean this up? Note: I'm pretty much a CLI know-nothing, sorry, but with minimal instructions on where to look and what to edit I do OK

thanks again to anyone who can help

 

SOLVED: I must have created the autoresponder before Mailman/the server had finished whatever cleanup it needs to do after a mailing list is deleted. I just deleted the nonworking autoresponder and created a new one (with absolutely identical settings) and now it works.
