[ILUG] {LONG} sendmail smart host & procmail recipies

[Declan Grady]

Hi again folks,
Apologies if this was covered recently.. I thought the list had died until I
realised in my shiny new sendmail config, I had forgotten an alias for
myself !!

Currently I have defined a "smart host" in my sendmail.mc file as:

define(`SMART_HOST',`smtp:mail.iol.ie')dnl

I would like to use this smart host, but only after attempting a direct
delivery.
i.e. I'd like my sendmail to try to deliver to the destination domain, and
if that fails, then send it to the smart host ?

Any suggestions ?

Another question.. I am still trying to use procmail (my lda) to reject
messages over a specified size limit, but I dont want to have to define this
for each luser. Can I define a system-wide .procmailrc to reject these
mails, but also have individual .procmailrc's for specific users, which
would override this ?

I have a working .procmailrc in my '/home/testmaxsize' folder, and it will
reject the messgaes over 350K in size:
