[Off Topic] Clients still not connecting to the FreeBSD mail server

Thanks again everyone for the pointers with Outlook and my fellow church
parishoners. I'm hoping for some more pointers. Using tcpdump I'm fairly
certain that the initial SYN packets from the clients are never reaching the
server. I'll need to test one more time to be sure (I wasn't 100% positive
of the public IP address on the Internet side of the cable modem installed).
Never the less, from home here I've verified what I should see if the initial
SYN packets are received at the server and now know what to look for. (Who
knows, maybe the wireless router knows it's in a church and has decided no
SYN's allowed. Ok, that was bad.)
What I'm hoping to glean from the experts here is about wireless routers.
I've never used them before, but one of the pastors was reasonably certain
that the problems commenced for the one person who never had problems, the
secretary, when she was switched from wired to wireless operations. Sunday I
was briefly able to see the administration pages of the wireless access
point, however nothing seemed to jump off the page at me that, "Yeah, this is
what's blocking them." However, it definitely seems that something is
preventing traffic over port 25 because we can all browse the Internet just
I've verified the same timeout behavior with Outlook Express and Thunderbird.
Using Thunderbird, I was able to check different settings too. The settings
should be to use authentication on the smtp server using SSL. Someone,
please educate me, does this mean that the authentication takes place over
port 465 and the regular smtp still takes place over 25, or do both take
place over 25? I ask because KMail (my setup at home that works) says to use
SSL, not TLS which uses port 465. At the server, I use sockstat and see that
on IPv4 sendmail has an open port on 465.
