Ah, the brief second window problem.

 

Got it. Thanks.

If you examine the badmail folder you'll note that there are multiple files
(usually) for each message. You pointed that out. Once ALL the files are
there, I agree that it doesn't get touched by the smtpsvc again. There is a
short window during the generation of those files (and I've hit it) where
the smtpsvc expects all 3 files to be present and if it isn't can generate
an error.

I agree with what you said for everything except for the badmail folder.
Once the e-mail has been put there (in 3 separate files) it is never touched
again by the smtpsvc, unlike the other directories, correct? Or is there
some point where the service may again access those files?

1) Even though the window is small, deleting files from under the SMTP
service while it's running can be A Bad Thing (tm). (Primarily event log
entries because the SMTP service may look for a file after it has been
deleted, or your batch file may abort because it tries to delete a file that
the SMTP service has locked.)

2) It renames the BadMail directory - when the SMTP service starts, and the
BadMail directory doesn't exist, a new one is automatically created (this is
documented and supported behavior).

3) It immediately restarts the SMTP service (to minimize the downtime - if
you wait until you've deleted all the files, your SMTP service could be down
for a long time.

Michael, why would you need to stop any service to delete files in the
badmail folder, as those are effectively dead files?
