Re: Yahoo! Mail Issue

We had a lot of issues delivering mail to yahoo.com.sg about a year ago
(just the .sg domain, plain .com was fine). Could establish connection
but it'd die halfway through transferring mail. A static route to drop
the MTU (for their subnet only) to 1000 fixed the problem right up.
Not sure if pmtud was/is broken or what.

Thanks anyway. I just find this issue intriguing since not all Yahoo
mail accounts are affected. In addition, incoming mails from other
domain doesn't seem to be affected. That is why I want to check if it
is a network issue :)

I imagine when port 25 stops giving 5xx
failure message back, mail reception
might improve. ^_^;
Works fine for me, your getting an error because your trying to send a
command before receiving the first 220, aka RFC violation. As long as you
connect, wait a moment without trying to send a command, your fine.
See, that's what happens when you ask networking people
to try to troubleshoot mail issues. ^_^;;
Sorry about that. :(
