Actually there was a bug with the mail spooler in 4.5, that I am told was
fixed in SP2, that caused this behavior.
It would only happen when you had a single template that executed more than
one cfmail in the same template, via a loop or just more than one instance
of the tag. Our experience with this bug was we could easily recreate it
but it wasn't as consistent as you have described. It seemed to very on
several factors... All based around the filesystem on the drive and the
relative access times to the spool directory.
From our own diagnosis, we found that the spooler appeared to be single
threaded in its filesystem writes to the spool directory. CF would begin to
write one file, then try to write another before it closed the first. We
would usually see 0k spool files in the spooler. Before SP1 the spooler
would then lock when it encountered the 0k file thus requiring a restart of
the service to resume mail operations.
Allaire never responded to us what the cause was, but 3 months into the
call tag, they did admit they could finally recreate the problem and that
it would be addressed in SP2. I have no idea if it was, as we long since
moved away from our CF spooler problems and use a different product to
spool all of our webserver generated mail.
It was our opinion that Allaire had little intention of correcting the
problem or packaging a robust enough spooler to meet our needs. We did
suggest that there wasn't enough disparity between Pro and ENT, and perhaps
the ENT package should include a fully functional multi-threaded smtp
relay. I suggest checking out aspmail or moving back to 4.1 :(
Don't know if it helps, but thought I would share.
PS. We were able to send out hundreds of thousands of emails a day using
single instances of cfmail tags, this bug only happens with more than one
tag, and it seemed the length of the email, or the inclusion of an
attachment greatly increased the likelihood of it happening.
