It works!
I used DR. TCP to change the MTU to 1400 and now I am able to send long
emails without problems.
What I do not understand is why did I had problems with my connection this
time. I mean I have reinstalled WinME every 4 months or so and never needed
to fix the default settings.
Anyway, I am happy now :-)
Many thanks to everyone for the help.
Happy 2002.
Cesar

Using the free utility DrTCP is the easiest way I know to change MTU
size. Download DRTCP.ZIP from
http://www.dslreports.com/r0/download/58303;f64d56211ff027c50aa88e39529ecedc
/DRTCP.zip
(Be careful if this link gets cut into two lines.)
There are instructions on using this utility at
http://www.dslreports.com/faq/tweaks/1.+DRTCP#1047
Basically, the program will run from anywhere. Unzip it to your desktop
for example. No installation required. Start the program by double clicking
the DrTCP icon. Highlight the value in the MTU box and change it. Hit the
Tab key so that "Apply" becomes enabled. Hit Apply and then Exit. Reboot.)
A lot of DSL users set their MTU to 1492. But you may have to experiment
with slightly different (smaller) values. (Try sending longer and longer
emails with different MTU values and find the MTU that works best.)
Don't forget to reboot after any change made to your TCP/IP parameters.
