Hi Benoit, and thanks a million for your reply. Yes, I have used telnet
to make a connection on both the imap and smtp ports that my Apache
James email server is listening on. I have successfully simulated
sending and receiving emails by manually typing in the appropriate
commands with lots of joy! Seems to work OK when making telnet
connections just fine.
However, what I am seeing when using Thunderbird as an email client, is
that when doing something multiple times, the connection and commands
work for a little while then things freeze up. For example, when
fetching emails from the imap service, I get a few emails and then it
hangs up. Ditto for running filters, the filters run for a bit, move a
few emails, then hangs up. I don't know what the magic is, for getting
back on track reliably, either. Sometimes restarting James and/or
Thunderbird does the trick, but more often it keeps on failing for
awhile and when I come back later it is running OK again. (again for a
little while) So I would like to see what is going on with the imap and
smtp communication layer itself to see if I can get any ideas.
I have looked at the Apache James log files also, of course, and no joy
discovering anything useful yet. One thing I do note is that only the
james-server.log and the wrapper.log files contain any information.
There are other files created, such as an imapserver.log file, but it
does not contain anything. I wonder if I have a misconfiguration
somewhere that is not allowing logging info to be directed to these
other files. I can't find any thing wrong with my configuration files
either, so for now I have set that problem aside while I try to pursue
the more serious problem of some kind of a spotty connection issue.
Maybe getting those other log files working would provide me with the
information I need to solve this?
I also see in the two log files that do contain information, exception
errors with walk-back stack traces, but those seem unrelated to what I
am doing at the time. (I get a LOT of bots doing brute force attacks
against my server and a lot of these exception errors seem to be related
to those attacks.)
I am using the Spring wiring for Apache James, and believe with log4j
logging. I will show the relevant property setting from the
log4j.properties files for the imap service. Why nothing is showing up
in the imapserver.log file is above my pay grade to grok.
log4j.appender.IMAPSERVER=org.apache.log4j.DailyRollingFileAppender
log4j.appender.IMAPSERVER.File=../log/imapserver.log

For your case, have you tried some commands yourself in telnet? I
suspect a connection problem, for instance firewall...
Best regards,

Hello, After doing a bit or reorganization of where the location of
installation files for Apache James, and or some updates I received
from Linux OpenSuSE 15.3 x64, something broke and I am now
experiencing some behavioral issues with my Thunderbird client -
Thunderbird - version 91.11.0 (64-bit)
Apache James - version 3.4
For example, I cannot seem to move some emails out of my Inbox
folder, and put them in another sub-folder. I don't see any error
messages, either from Thunderbird itself, nor in any of the log files
from the Apache James server. And the moved emails do disappears from
the Inbox folder temporarily only to reappear back in the Inbox
folder a little later. Another symptom that has show up is
Thunderbird keeps reporting that it cannot save a copy of my draft
emails while I am composing it.
So my question is, what is the best way to monitor the IMAP protocol
communication that is going on between my Thunderbird email client,
and the Apache James server? Can I capture it via the log files for
Apache James or must I learn how to use a low level network monitor
such as Wireshark? If the latter, are there any gurus around to show
me how to capture just the IMAP communication?
As always, much appreciate any thoughts and advise and thanks for
taking the time to help me! Marc C
