mod_vacation might flood admin user

[jens]

In my jabber server there is a user 'admin@…l' with acl type='all'. This user is usually not logged in. For this user has been deposited a vacation message. When another user sends a message to 'jabber.local' (sm self), the sm sends as 'jabber.local' unlimited messages to all users with acl type='all' and type='messages' until the server shuts down. Sometimes the storage server crashed because it stored many offline messages. I think that the error is as following: The sm forward the message to 'jabber.local' as 'jabber.local' to 'admin@…l'. For this user has been deposited a vacation message. The sm answers the sender as 'jabber.local' with the vacation message. In this case the sender is 'jabber.local', the sm self. This message will be forwarded to administrative users. In particular to 'admin@…l'. Now the loop beginning.

Yes, this is the possible scenario. It's a problem with any auto-responder system.

How do you propose to solve it?

I have disabled the vacation message temporary.

But this is not a solution. How would you like it resolved?

The auto-responder shouldn't reply to messages which sent from sm. (sender has not @ in address) What do the auto-responder with broadcast messages? He shouldn't reply too.

Good idea.
