port 25 dead

[Evan]

i'm trying to send an e-mail via outlook express. mail won't send. i switch
identities (i've got 3. none of them will send). can't send from there
either. i disable my firewall. can't send. i do some poking around. here's a
good test: telnet in to the mail server. this, i CAN do successfully on port
110, but NOT on port 25. i go to my laptop. i CAN telnet into port 25 from
there.

so, on my main pc, SOMETHING is up with port 25, but i don't know what. can
anyone recommend what the hell i do from here?

(btw, this is actually a wxp sp2 box, but i didn't see an xp.networking
forum.)

thx!!

Uninstall, not disable, firewall software when testing. Many firewall
programs say they're disabled but they are not.

thx, richard. unfortunately, that didn't help. btw, i forgot to mention, i
had also tried repairing the connection and i also un/reinstalled the
network adaptor.

i'd LOVE to hear more ideas, if you got any.

I suggest you start by establishing that the packets are
actually leaving your PC. Install the Ethereal packet
sniffer (www.ethereal.com), then telnet first to a
responding port 110. When you become familiar
with the recorded packets, change to port 25. The
results should tell you quite a lot.

You will probably find that a firewall blocks your
packets somewhere, as Richard suggested.

okay, my isp IS in fact blocking port 25. once i knew that, the fix was
easy. thx guys for your help and input!

There is something strange going on here. In your first post
you wrote "i go to my laptop. i CAN telnet into port 25 from
there.". Now if the problem was caused by your ISP then
port 25 would not have worked from your laptop either . . .
Or is it perhaps that the results from the laptop test were
just wishful thinking?

i was hoping no one would notice that...

my laptop is not going through my router, but rather through my neighbor's
wireless network (yes, he knows. i even offered to pay him). BUT...we're
both on sbc dsl, so i just *assumed*...

as a matter of fact, i still don't know why i can telnet port 25 through his
sbc connection but not my sbc connection. i even tried bypassing my router
and going straight pppoe. no luck.

anyways, that's the contradiction you were clever enough to notice. now to
the bonus round... ;-)

Your initial report about the laptop working set the scene
for all replies from Richard and myself. The incident is a
perfect illustration that one must never change more than
one parameter at a time when trouble-shooting.

Had you mentioned this fact the first time around you probably would have
had an instant answer, but like everyone else I assumed you were talking
about two computers on the same connection.

my apologies to you both. i was not intentionally misleading you guys. i
honestly believed (and still believe) that because we were both on sbc (and
live across the hall, fer crissakes!), there should have been no difference.
i was wrong. i do appreciate both of your help.

To add to my previous observation: Either Richard or I
would have suggested to telnet to a different SMTP
server. I could even have given you a suitable IP address.
This would have pointed the finger immediately at your
own ISP, and saved you a great deal of trouble . . .
