Description of problem:

After upgrading from F36 to F37, sending emails was no longer possible. Sendmail did not start the authentication process and/or did not accept user/password any longer.

I have been using my sendmail.mc for the past 10 years and it worked perfectly until I upgraded to F37.

Turns out that the following directive breaks the sending functionality (authenticated submission via implicit TLS):

define(`confAUTH_OPTIONS', `A p y')`

After changing it to

define(`confAUTH_OPTIONS', `p y')`

sendmail starts working again.

Version-Release number of selected component (if applicable):


How reproducible:

Steps to Reproduce:
1. setup sendmail to send emails via submissions on 465 with authentication
2. send email

Actual results:

Error message: Relaying denied. Proper authentication required.
Server logs show that authentication was not even initiated.

Expected results:

The client should authenticate against the server and the mail should be sent.

Additional info:

The mail client is irrelevant. I haven't changed it for a long time (not even upgraded it, since I need its functionality that was removed with a later version), but I have also tried other (newer and most recent) mail cilents.

For completeness I will attach my sendmail.mc (even though I don't think it will help, except for you to see that I didn't screw up my config.)

Interesting. testsaslauthd works just fine (which is something I forgot to mention in my bug report), so I guess sendmail's integration with SASL is borked and not sasl itself.
