Why can't sendmail just play nicely? Only accepts mail on localhost..

My sendmail server can send and recieve, HOWEVER I cannot use like Outlook, or Mail.app on mac or anything because it seems as if sendmail just rejects my request. How can I get sendmail to accept or relay email from any ip address? or when the @mydomain.com is in the from line? I have the slightest idea..

Did you properly setup relaying? and please, NO OPEN RELAYS! 😉

i second that. sendmail.cf is quite a monster... i havent touched it in a while.... best advice i can give is.....

use postfix or qmail!! even though qmail seems backwards in its setup.
 
qmail isn't free. Which is a damn shame since it seems to be the best mail server out there. Except that whole DoS thing... Setting up Unix limits is generally very poorly documented. 😉
 
you could gluge on auth before smtp, but the ssh tunnel is by far the best solution ... you could also use webmail like squirrelmail, and then localhost would work fine
 
I have webmail, I want to use my email client and I want to be able to connect to it wherever I am using my Mail.app program. What can I do to fix this? accept mail from any ip?
 
relaying from outside your network is tricky, as it can expose you as an open relay for spam if it is setup incorrectly. AFAIK sendmail doesnt support auth before smtp out of the box, its more of a hack to get it to work. here is a link you might want to check out:

here is a decent link on how to set it up with postfix:

make sure you have your mail scanner scanned for open relay after you set it up

You're wrong. Check again. 😉

An ssh tunnel is probably the easiest way to do this. Shouldn't be too tough.

agreed, certainly a lot better than getting auth/pop before smtp working in sendmail
 
well i know that the license on anything DJB has coded causes many people stress, but I cant find any reference to payment and I havent heard of anyone writing DJB a check... maybe i skimmed over the site too quickly.

The license is a non-free license.
