Description of problem:
There's a bug in 8.12.11 that was fixed upstream in 8.13.2. The release notes describe it best:
If a server returns a 421 reply to the RSET command between
message deliveries, do not attempt to deliver any more
messages on that connection. This prevents bogus "Bad
file number" recipient status. Problem noted by
Allan E Johannesen of Worcester Polytechnic Institute.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Try to send 2 mails to an address @aol.com from a host with no reverse DNS
2. Observe the first one rejected properly with a 421, the second with a "Deferred: Bad file descriptor" status.
Actual Results: See above
Expected Results: the second mail should have a "Deferred: 421..." status instead
It's fixed upstream, please just incorporate their fix.
I am sorry, but the fix is very large, because it has to get fixed in several
parts of sendmail. Even 8.14.0 still contains fixes for 421 returns.
Closing as WONTFIX.
