smail problems (dial-up)

["Moore, Paul" <Paul.Moore@uk.origin-it.com>]

Hi,
I'm just getting smail set up, and I'm not sure what I need to do for
the last stage (getting my dial-up setup working). I have local mail
setup fine, including redirecting "postmaster" mail to my normal
account. My ISP (Demon Internet in the UK) passes mail to me using SMTP
when I am logged on, so receiving mail seems to be no problem (I just do
pon and wait, Demon passes the mail to me fairly promptly). 

For outgoing mail, I have Demon's mailer set up as my smarthost. If I
send a message while offline, the smail log includes a line saying there
is an error, can't find post.demon.co.uk, deferring mail (OK, that's
right although as it is the expected situation, I'd rather it wasn't an
error...). However, when I start up the PPP connection with pon, nothing
seems to trigger smail to send deferred mail.

I found a command "runq" which seems to push stuff through. Is that what
it's for? If so, how do I get this to happen automatically when I start
the PPP link? Did I miss something in the configuration setup to get
this added automatically? All of the rest of the setup was put in as I
expected (I told the config that I was a dial-up Internet site, from
what I recall...)

As usual, if I do have to do manual tweaks, what do I need to do if I
later want to use dpkg/apt to upgrade or change things (for example, god
forbid, I need to switch to sendmail...)

Thanks for the help,
Paul.
