The possibility do exist...  :-)

So far so good.  Note that you're going to have a problem if your
libtiff is 3.5.0 to 3.5.4.  Older ones, and 3.5.5 and up, will work
ok.  The symptom is that outgoing faxes never go; faxq will have a
child faxq that just churns...

You can check this with

# rpm -qa | grep libtiff

I think so.  Check /var/spool/fax/etc/hosts, first.  This file decides
who's allowed to send faxes through your server.  It must include
127.0.0.1, at the least, and the IP addresses (or network numbers;
'192.168.128.' would be an acceptable syntax) for the machines on your
net you want to have access.  Check this first, and if this isn't it,
determine whether the fax server machine has a firewall... or the
client machine does.  Like FTP, the data connection is built in
reverse, from the server back to the client (I *think*; isn't that
right Darren?), so if the client won't allow the connection, it won't
work.
