Best way to deliver mail?
 

Hello,

I'm trying to figure out the best way to send email via dial up modems/batch processing. I work at a retail company and we connect to store computers once a night via dial up modems. We send data between store and corp via uucp. We've currently been using sendmail to send emails, but I'm wondering if there is a better method. I'm rolling out a new "clone" on CentOS 5.1 and was thinking there may be an easier way to accomplish this. I want to make sure that our stores can only send emails to @domain.com, and not @hotmail.com, @gmail.com, etc. What's the best method to achieve this?

Any help is appreciated.

Thanks,
Jared

I would take a look at one of the sendmail offline guides like: http://www.sendmail.org/~ca/email/offline_mailing.html

Other mailers have similar ways to do things. Here's one for qmail: http://uk.geocities.com/blimp001/bent/guide.html

I had a quick read at the postfix site, and there's a section here

http://www.postfix.org/rate.html

that should help
