I have a server which I upgraded recently from 2.3.13 to 2.3.14.
Now I realized that sending mail to shared folders doesn't work anymore.
I have verified the problem on a test box and it looks like this:

May 28 11:01:49 install lmtpunix[15085]: accepted connection
May 28 11:01:49 install lmtpunix[15085]: lmtp connection preauth'd as postman
May 28 11:01:49 install lmtpunix[15085]: verify_user(system) failed:

The mailbox has the following permissions:

I just downgraded to 2.3.13 and it works again, upgrading to 2.3.14 and it

Somehow there was a change from 2.3.13 to 2.3.14 which triggers the
problem. I tried to identify which change it is but can't find it.

Another interesting detail is that both servers where it doesn't work are
RedHat EL4 on i386 while I have a server RedHat EL5 on x86_64 where it
seems to work.

Does anyone who knows the changes between 2.3.13 and 2.3.14 have an idea
what could be the problem here?
