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):
sendmail-8.13.2-1

Actual results:
A simple upgrade (new versions in the spec file) did it for me - 
without any patch merging.

Expected results:
Upgrade to 8.13.3 ;-)
