Gmane hasn't been able to deliver mail to eggs.gnu.org since this all
began, and there's currently 50 mails in the queue.  (I think they've
started to time out completely and be discarded from the queue.)  The
Gmane servers are in Norway, and are IPv4 only.

I've included some lines from the log below:

2016-05-16 11:07:43 1b1sbi-0006i0-7X == emacs-orgmode@gnu.org R=dnslookup T=remote_smtp defer (-46): SMTP error from remote mail server after end of data: host eggs.gnu.org [208.118.235.92]: 421 eggs.gnu.org SMTP incoming data timeout - closing connection.

2016-05-16 11:19:41 1b0mfX-0002hb-EF == bug-lilypond@gnu.org R=dnslookup T=remote_smtp defer (110): Connection timed out: SMTP timeout while connected to eggs.gnu.org [208.118.235.92] after end of data (2646 bytes written)
2016-05-16 11:36:50 1b2Bkb-0001o5-Mo == emacs-orgmode@gnu.org R=dnslookup T=remote_smtp defer (110): Connection timed out: SMTP timeout while connected to eggs.gnu.org [208.118.235.92] after end of data (2698 bytes written)

In addition, now and then I see lines like

2016-05-16 11:55:10 1b0wxV-0002ct-9J eggs.gnu.org [2001:4830:134:3::10] Network is unreachable

Which is very odd, since there's nothing IPv6 configured on the server.

Telnetting to the server works, and I can talk to it, but it times out
after the final "." of the email.  Which makes me suspect that it's
doing some kind of spam filtering, and the spam filter is timing out.
