I am having an interesting problem with iMail version 6.03.
When I clamp down the security a bit to only allow relaying from authorized
users of a domain, it works fine for a while. A random interval between a
week and about a month. Then after a non-specific amount of time, I start
getting 'Unknown Recipient' error messages. Funny part is that once this
happens, the only way I've found to resolve the problem is to open the
security of the server back up.
There doesn't appear to be anything odd in the logs. It looks like the mail
server just forgets all of the mail accounts set up in it.
Has anyone experienced this and how did they resolve it?
