Where would I find these? Other than in /etc/imapd.log

# ls -lA /var/lib/imap/socket/lmtp
srwxrwxrwx. 1 root root 0 Nov 29 14:38 /var/lib/imap/socket/lmtp

I did:

[root@dell2600-1 brad]# ls -l /var/lib/imap/log
total 0
[root@dell2600-1 brad]# mkdir /var/lib/imap/log/brad@xxxxxxxxxxxxxxxxxxxxx
[root@dell2600-1 brad]# chown cyrus
/var/lib/imap/log/brad@xxxxxxxxxxxxxxxxxxxxx

[root@dell2600-1 brad]# ls -l /var/lib/imap/log/
total 4
drwxr-xr-x. 2 cyrus root 4096 Nov 29 16:51 brad@xxxxxxxxxxxxxxxxxxxxx

then re-connect from another client on the network using Thunderbird
Mail. I then see:

[root@dell2600-1 brad]# ls -l /var/lib/imap/log/brad@xxxxxxxxxxxxxxxxxxxxx
total 52
-rw-------. 1 cyrus mail 25990 Nov 29 16:59 imaps-4288
-rw-------. 1 cyrus mail 21539 Nov 29 17:07 imaps-4646

I think that's as expected?

I looked at # man lmtptest, but I don't begin to understand! Not
surprising since lmtptest seems to be a  debugging tool for developers,
which I definitely ain't :-(

Perhaps  you would be kind enough to post the specific lmtptest command
I should use and the expected result.
