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.
This request was evaluated by Red Hat Product Management for inclusion in a Red
Hat Enterprise Linux maintenance release. Product Management has requested
further review of this request by Red Hat Engineering, for potential
inclusion in a Red Hat Enterprise Linux Update release for currently deployed
products. This request is not yet committed for inclusion in an Update
This patch bas been reverted. There is a new version of the 421 handling for
8.13.4, 8.13.5 and 8.13.6. The latest patch is very invasive.
This is a no go from my current point of view. It would be good to go to 8.13.7
at least, but 8.13.7 fixes a regression of 8.13.6. Best would be 8.13.8.
Not appropriate for an update release, needs an update of the upstream
sources to fix.
