Description of problem:
Sendmail, Inc., and the Sendmail Consortium announce the availability
of sendmail 8.13.3. It contains fixes for a regression that was
introduced in 8.13.2. Moreover, sendmail now keeps proper track of
closed connections and will not reuse them erroneously.
Note: Before these bug fixes more mails could be delivered to a
domain despite errors on the connection. In some cases the old
behavior is preferred because it more "aggressively" delivers mail,
but the new one is "correct" with respect to the algorithm that is
supposed to be implemented. On systems with large queues for single
domains this may cause a noticeable change in behavior if the MTAs
of the recipient domain close connections with an error that sendmail
considers persistent, e.g., 421.
Version-Release number of selected component (if applicable):
A simple upgrade (new versions in the spec file) did it for me -
without any patch merging.
Upgrade to 8.13.3 ;-)
Fixed in rawhide in rpm sendmail-8.13.3-1 or newer.
