[ic] Mail notification

[Sergiusz Jarczyk]

Dear All
Although I'm working with IC for a while, this simple problem is still
unresolvable for me :-)
I have IC 4.9.5 installed on RH8.0, and I can't make it to send e-mail
notifications about orders. There are no entries in error.log, as well as
maillog, about even trying to send something. I found in interchange.cfg an
entry Variable MV_SMTPHOST, but it doesn't matter if I set this, or comment
this out.
Can someone point me to any doc, describing SMTP config for IC?

TIA,
Sergiusz
