RH 9.0: AUTH LOGIN issue with latest sendmail patch

[Christian Becker]

Hi all,
Yesterday's sendmail update for RH9, going from 8.12.8 to 8.12.11, broke
AUTH LOGIN for SMTP on our machine - all logins were rejected; logs were
filled with "xyz did not issue MAIL/EXPN/VRFY/ETRN during connection to
MTA".
For anybody else affected: The fix for me was to copy
/etc/pam.d/smtp.sendmail to /etc/pam.d/smtp. The latter file seems to get
deleted during the update. A similar issue is described at
https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=109313
