I didn’t do this myself so I can’t vouch for it, but there was a recent discussion on one of the mailing lists I’m on about getting Sendmail to work with Rogers Smarthost settings.
Apparently this howto:
Will get you going, but there is one critical change you must make as determined by the Hugo on the mailing list.
Don’t forget to use smtp-rog.mail.yahoo.com in authinf and not smtp.broadband.rogers.com!
Also, if you want to use an external authinfo file, add this to your sendmail.mc file.
FEATURE(`authinfo’, `hash -o /etc/mail/authinfo.db’)dnl
Again, I didn’t try this myself, but I know some of you use Rogers and this may come in handy.
