Description of problem:
I have set up sendmail authentication on previous releases or Redhat
(notably 8 and 9) with absolutely no problems. I followed the
guidelines offered here at
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Follow link provided above.
2. Try to send mail with a client setup with SMTP Authentications
Actual Results: Client can't authenticate. It just gets
asked/re-asked for its password over and over. This shows up in the
maillog when client finally stops trying to send.

[192.168.1.103] did not issue MAIL/EXPN/VRFY/ETRN during connection to MTA
Expected Results: Client will authenticate and send mail to expected
This method has worked perfectly until now with Enterprise ES 3.
Clients are set up correctly, sendmail is set up correctly. Either
sasl or pam are not cooperating and I can't figure out which. I have
added the /etc/pam.d/smtp file as well as the
/usr/lib/sasl/Sendmail.conf and /usr/lib/sasl/smtpd.conf files. Still
the same results after restarting services. I noticed 8.12.10 uses
sasldb2 instead of sasldb. However, adding the Sendmail.conf and
smtpd.conf files to usr/lib/sasl2 seemed to do nothing different.
Oops! Noticed a typo in the link. Here's the right one...
exactly same problem here.
using sendmail 8.12.10-1.1.1
worked before on RH9 with sendmail 8.12.8
well, found out what was causing the problem..
saslauthd was not running :P
fixed the problem for me
I did have saslauthd running, but the problem ended up being that cyrus-sasl-devel
package was not installed at initial installation. It only gets installed if you choose the
"Development" packages. I also updated to the 2.1.17 sasl2 libs. Between the two of
them, I stopped getting the "unknown password verifier" error message in the
messages log. So...it's up and running now. Perhaps making the cyrus-sasl-devel
packages install with sendmail would be a good idea?
I have installed sendmail-8.12.11-3 ( src file ) ( found in
After buiding the package, the SMTP_AUTH with pam doesn't work.
The link /etc/pam.d/smtp -> /etc/alternatives/mta-pam doesn't exist.
If I create this link, SMTP_AUTH with pam work.
