Using sendmail to send mail from your ISP


I am currently hosting a site on my server. The IP is dynamic and listed on the SORBS spam blocking list. So I am trying to to force sendmail to use my ISP's server for send outgoing mail. I added the following lines to my

define(`SMART_HOST',`')dnl <--- Your ISP's mail server name goes here
MASQUERADE_AS(  ><--- Your ISP's domain name goes here
but the outgoing mail comes back saying I need authentication.

How do I get senmail to authenticate my ISP's server before sending mail?

You'll need to contact your ISP.
They'll have the appropriate port numbers and username you should be using to configure your mail client (check you ISP's web site since this info is probably posted in one of the FAQ's). You'll also want to see what your ISP policies are regarding the use of their mail servers.

Thanks a lot for your advise. That solved the problem. I called my ISP and got the info. As it happens my ISP uses my IP to authenticate SMTP on theri server. So as long as my IP is part of their IP block it sends my mail. The problem was that I was using the wrong SMTP server.
