Just for the sake of completeness, this wasn't actually an issue with the
GreetPause option or anything else in the access file. The problem was
that sendmail was attempting an IDENT query to the client, with a 5-second
timeout. The access file wasn't even checked until after the timeout
expired.
Thanks, but it looks like the IDENT setting was the culprit. I just had to
change this setting in sendmail.cf:
O Timeout.ident=5s
Changing it from 5s to 0s resolved the problem immediately. Thanks again,
everyone!

Hello,
My /etc/mail/access file is pasted below. The PC I'm testing from is on the

but it still made no difference.

Yes! That seems to be the culprit. I ran an strace on the sendmail
process and that's exactly what happens:

Thanks for the replies.
The system is not using tcpwrappers, and it's also not a DNS issue. The
client PC does have a reverse DNS entry. A tcpdump packet capture on the
server shows the initial connection from the client followed by a bunch of
DNS traffic, all within the same second. Then nothi

Hello,
We have an SMTP server running Sendmail 8.14.4-4 on Debian 7 64-bit. We're
using the file /etc/mail/access for access control and rate limiting, and
this is enabled via the following lines in /etc/mail/sendmail.cf:
Kaccess hash -T /etc/mail/access
# FEATURE(`access_db', `hash -T /etc/mail
