From here, I can resolve Elein's domain just fine, but when I tried to
email her to point her at this discussion, I got

Nov 16 15:43:42 sss2 sm-mta[634]: kAGKcgcE000631: timeout waiting for input from mail2.norcov.com. during client
greeting
Nov 16 15:43:42 sss2 sm-mta[634]: kAGKcgcE000631: to=<elein@varlena.com>, ctladdr=<tgl@sss.pgh.pa.us> (301/20),
delay=00:05:00,xdelay=00:05:00, mailer=esmtp, pri=120459, relay=mail2.norcov.com. [64.81.253.169], dsn=4.0.0,
stat=Deferred:Connection timed out with mail2.norcov.com. 

According to netstat the connection never got out of SYN_SENT state,
ie, no ACK ever came back.  So I concur it's some kind of connectivity
issue at her ISP.

(Interestingly enough, the third retry a few minutes later got through.
So it's also intermittent.)
