sendmail can't send to hotmail address

[phil at 1918.com (Phil Buckley)]

I'm running a RedHat 7.1 box, equipped with sendmail 8.11.2 and a
simple firewall...

The trouble I ran into this morning is a new one to me... I set up a
user in /etc/mail/virtusertable with a pointer to her hotmail account,
then ran a basic "sendmail -bv -d27 user at virtualdomain.com" test on
it.... and it just hung.

So I started with the easy stuff, re-re-built the hash, re-re-started
sendmail and tried again, same problem...

Checked my firewall, access files, stuff like that... nothing even
remotely close that would stop it...

Checked some stuff on goggle groups... Apparently I'm not alone...

Found these in comp.sendmail:
======================
1: Jan Albin "rediscovered" (in another thread) problemcaused by
blocking
tcp queries via tcp by firewall [ it was discussed long time ago in the

group ]
and suggests that hoymail problem may be caused by it.
Some replies are too big to fit in udp packet so DNS server/resolver
tries
to contact a remote DNS server via tcp which is blocked.

2: Opening up the firewall to allow DNS on port 53 TCP solved the
problem.
======================

So I opened up my firewall as suggested ( I started my firewall using
pmfirewall):

#DNS
$IPCHAINS -A input -p tcp -s $REMOTENET -d $OUTERNET 53 -j ACCEPT
$IPCHAINS -A input -p udp -s $REMOTENET -d $OUTERNET 53 -j ACCEPT

$REMOTENET = 0/0
$OUTERNET = eth0 (outside nic)

I mapped a user topoint at my own hotmail account...
phil at domain.com	guy_nearby at hotmail.com
---makehash
--restart sendmail

# sendmail -bv -d27.99,28.99,60.99 phil at mydomain.com
setalias(/etc/aliases)
  map implicit:Alias0 /etc/aliases
map_lookup(dequote, phil, %0=phil) => NOT FOUND (0)
udbmatch(phil, mailname)
db_open(/etc/mail/userdb.db): No such file or directory
map_lookup(host, mydomain.com, %0=mydomain.com) => mydomain.com. (0)
map_lookup(dequote, phil, %0=phil) => NOT FOUND (0)
map_lookup(virtuser, phil at mydomain.com, %0=phil at mydomain.com, %1=phil)
=> guy_nearby at hotmail.com (0)
map_lookup(host, hotmail.com, %0=hotmail.com) =>
.... still hanging .....

Any ideas?

TIA,
Phil
