From: klee12 on 27 Jun 2008 15:36 Hello, I running Slackware 12.0 with sendmail. I use a cable modem with DHCP. Recently many of my outgoing mail has been returned because of a spam blocker. I was told I should use the cable modem companies mail exchange; some spam blockers are sensitive to DHCP addresseses. I should, he said, use the mail exchange cdptpa-smtpin01.mail.rr.com OK, can anyone tell me how to do that? Thanks in advance King Lee klee12(a)yahoo.com

Using a cable modem has no special effect on your actually chosen mail host. And this problem is not related to slackware. > some spam blockers are sensitive to DHCP addresseses. > I should, he said, use the mail exchange > cdptpa-smtpin01.mail.rr.com That's much more nonsense. "rr.com" is listed in many lists for spamming. > King Lee > klee12(a)yahoo.com That looks like a yahoo mail account - have you used this account when you got so many returned mail?

In /usr/share/sendmail/cf/cf/sendmail-slackware.mc (or in whatever .mc file you keep the source code to your current configuration), there is a SMART_HOST directive. Uncomment it to use the server you indicated, like this: dnl# Uncomment the line below to send outgoing mail through an external server: define(`SMART_HOST',` cdptpa-smtpin01.mail.rr.com') Then build a .cf file out of that .mc file: ../Build sendmail-slackware.mc Copy the resulting .cf file into /etc/mail/sendmail.cf and then restart sendmail. It should now relay all outgoing mail through the indicated smarthost. Note that there is a comp.mail.sendmail newsgroup. - Martijn

You misunderstood the problem. Due to the spam situation, most major email providers now block mail that is sent directly by residential (often dynamically assigned) IP addresses, such as those assigned to cable modems. Mail relayed through the ISP's smarthost has a much higher chance of being delivered. - M.

Correct, and if the OP doesn't like the idea to modify and or ./Build there's an even lighter way: $ su - # cd /etc/mail # echo ".<TAB>cdptpa-smtpin01.mail.rr.com" >> mailertable # make # exit (of course the '<TAB>' implies a "real TAB key press :-) Note that if there were existing mailertable rules they'll be maintained, but I doubt there were or the OP wouldn't have posted his questions ;-) |
