I have NEVER seen it happen at the 'user' level... keep in mind that the
'domains' and 'users' are both authmysql accounts.
Everything works normally most of the time, and while I have reached some
capacity issues, it has been solved usually by either upgrading the mysql DB,
faster disks, et al.
Any suggestions would be appreciated. I can forward config files privately if
needed.
I'm afraid you will have to investigate this on your own, since only you
have access to the entire system, and have access to the entire data.
Randomly looking at random configuration files is not very likely to produce
any useful results. Since you indicated that everything works "most of the
time", it means that most of your configuration is fine, except for one tiny
bit, so this will translate to looking for a needle in a haystack. You will
need to make the haystack smaller, by understanding under which conditions
the problem occurs.
Take a sample forwarding failure, and investigate it. Look at the account,
look at its forwarding files. Verify the addresses it's trying to forward
mail to, etcâ
This is basic troubleshooting. You have to be able to say: this is the
address that always fails to forward its mail; this is the MySQL record for
this account; these are the domains listed in hosteddomains/locals; this
is the contents of the account's home directory; this is what the .courier
file for this address is doing, etcâ
