To all,

I setup a Sendmal Server for the purpose of connecting different users in diffent location with different DSL connection, 3 commissary, 6 offices, 118 branches, etc.

What configuration can you recommend? I tried using SMTP AUTH so that it will not be depend on IP addresses since some users have dynamic IPs. However I having this error message when sending to Yahoo

Relaying temporarily denied. Cannot resolve PTR record for 202.x.x.x

I already enable the saslauthd and CA cert...

Please help!

you need to enable _any one_ of the following two in sendmail.mc
(the second line is deactivated in this example, since i can afford to allow plaintext authentication over a non SSL/TLS network, since this is purely in a private LAN at home).
and make sure the following lines appear as it is in the sendmail.mc
Rebuild your sendmail.cf, and restart sendmail. you will have SMTP AUTH enabled in sendmail.

Hi,

I am trying to configure Sendmail with AUTH & SSL. My problem is i am able to send mail without getting authenticated.

I have visited most of the sites to configure this, my configuration resembles same,but i am not getting authenticated. "250 AUTH" doesn't appear in the test.

I need your assistance to figure out my mistake.

Herewith i have attached the relevant details.
