I may be wrong, but doesn't MailScanner once installed take the place of
"sendmail" as far as control?

> - Later in init, sendmail starts with an [ OK ] result.
> All seems well. Furthermore:
> from somewhere outside, telnet myserver.net 25 results in a normal
> conversation with sendmail, from MAIL FROM:<...> through DATA ... all
> the way to RSET and QUIT. 200-code success on every command.
> The message from said entirely normal conversation seems, by all

> the recipient's mailbox. Yet:
> % service sendmail status
> sendmail (pid blah blah blah) is running...
> % service dovecot status
> dovecot (pid blah blah blah) is running...
> when I go to the sendmail module of webmin on that server, the
> start/stop button at the bottom is showing the START option, not the
> STOP option, and once I click Start Sendmail in webmin, sendmail begins
> actually functioning correctly.
> - Why does sendmail indicate itself to be running to the service command
> (and the init script), and carry out valid conversations on port 25, if
> it's not really running [correctly]?
> - Where do those messages go?
> - And how come only webmin is alert enough to realize that sendmail is
> in fact /not/ running [properly], and is able to correct it? What does
> it know that I don't? (obviously lots, but still...)
