That's not good. I've not known about any drh.net e-mail problems. Please
forward me some of these error messages at davideousNOSPAM @ yahoo.com. (Of
course, remove the "NOSPAM" from the e-mail address.)

First, make sure you are running the latest version: smtp-poplock-2.04. You
probably are.. but just checking.

Ok. That's a bug. That will be fixed in the next version. Thanks for the heads
up.

Checkfifo does the following: it writes data to the fifo until it gets filled
up and blocks on writing, then it waits 90 seconds, and then checks to see if
it can write to the fifo. This is a check to make sure that the fifo will be
cleared if readlog is not running. It is just a test of fifo-safety, really.
So, disable readlog, enable fifo-safety, and give checkfifo a try.

Readlog was never intended to be running during a checkfifo run. Results are
undefined.

What is your value for $pidfile from /etc/smtp-poplock.conf?

Can you give me a nested process listing (like 'ps -axf' on linux) so that I
can see where this has hung? Also, it's very important to have your values for
the logpopauth_where, readfile, readfile_isfifo configuration variables and
which data passing method from the INSTALL file you chose to implement.
Also, have you checked to make sure that POP works properly when logpopauth-pre
and logpopauth-post are removed?
