Ok, and just to be sure, at that situation when probing with those 2
commands I gave you your Sendmail is queuing the mail and not sending? I
ask because the map lookup right below succeeds and so mail to
anyone@xxxxxxxxxxxxxx should go directly out and should not be deferred.

The lookup is proper. The only thing right now I could suggest is to
disable IPv6 with following line in the /etc/modprobe.conf

install ipv6 /bin/true

Looks ok too. The only thing you will face is, that your private domain
name AAA and the FAQD P4.AAA is not resolvable for any mail host
outside. So many MTAs will reject your mail and not accept it. Therefor
I asked you to better choose your ISP's SMTP server as smart host.

Good.

If with "localhos" the missing "t" is just a pasting error.

A last question. You showed us a mail being in queue with "mailq -v"
output with recipient <phd2@xxxxxxxxxxxxxx>. Is only that one queued
after the initial start of Sendmail after a reboot or every recipient?
