Hi guys, glad to see this thread is still active and you are still finding this Howto usefull.
Some good news, it seems that in the last few days Slackware -current has added Sendmail 8.13.4 compiled with SASL support!. So it looks like half of my Howto just became obsolete In anycase, I removed my custom-compiled slackware package and used the new sendmail-8.13.4-i486-1.tgz (as well as cyrus-sasl-2.1.21-i486-1.tgz) and restarted sendmail and everything works great with my existing cf file!
As far as pine not working but mutt does, I have no idea. I just tried pine right now and it worked fine with SMTP auth via SMART_HOST to my SBC account.
One thing I noticed is that it didnt say Mech=PLAIN (which is what my SBC has always used). So just doublecheck you have these two lines in your .mc file.
SiegeX (or any one of you Slackware/Sendmail gurus), could you please help me out here?
I'm using Slack 10.1 and the version of Sendmail that came with it (8.13.3) and all I want to do is be able to use that server to send messages to the outside world (eg. firstname.lastname@example.org), instead of my ISP's server. That's possible, isn't it? I'm not sure what I need to do. Sendmail accepts the messages from my mail client (Mozilla) or PHP scripts I have, but the sending of them fails because of "host name lookup failure" errors. I haven't found anything that can help me with this.
I tried to go through your tutorial, Siege, but I got stuck trying to run ./configure on cyrus-sasl. I get the error message, "configure: error: invalid variable name: --with-saslauthd". This happens with both cyrus-sasl-2.1.21 and cyrus-sasl-2.1.19.
Like I said, I just want to be able to have a working Sendmail server, one that will let me email the world . Am I doomed to failure? If anyone can help, thanks much .
Also, one thing to note is that if you are on a residential IP netblock (ie you are using non-commercial DSL or Cable) then even if you get this to work, id say about 40% of your mail will be dropped by many SMTP servers in attempts to stop spam which mostly come from hijacked residential computers. For this reason, I use SMART_HOST which is explained in the FAQ.
The almost-final step is to turn on mailertable support in sendmail. So log in as root, go to /usr/share/sendmail/cf and edit up the .mc file, adding the following line (note that the funny quotes here are important):
Last question: for packages that weren't installed when Slack was installed, they won't show up in /var/log/packages, will they? I installed Webmin with pkgtool and it doesn't appear there, so I couldn't remove it if I wanted to. I guess if I wanted to remove Sendmail after installing it from the new packages, I'd not be able to remove it. I can of course remove the Sendmail packages I've got installed now.
