The users have said they were able to send using other servers

When I look at my system, its unable to resolve the domain name.

DNSSEC failure on their end.
I had checked my dnssec.log, but nothing for usda.gov in it...but now that I
look closer, the file hasn't updated since Jan 29th....seems somebody changed
the resolv.conf on my smtp servers...so I've been looking at the wrong
caching servers.
Guess this latest problem with usda.gov started around 10:16 CST...though
there are errors logged going back to Nov 19 (the first log line is Nov 17
00:16, and the 10M file before has nothing for usda.gov, from Nov 14
18:46...wonder if I dare keep more dnssec logs)
