Can you be more specific? My TCP/465 and TCP/587 mail submission works great over Sprint. I'm not even trying to do submission on port 25 (in fact, my mail servers send rude messages if you try AUTH to a port 25 listener) so I can't speak to that. -r Owen DeLong <owen@delong.com> writes:
While you're at it, it would be nice if SPRINT also fixed the problems with ports TCP/25 and TCP/587.

Dear Sprint EVDO people,
Your man-in-the-middle hijacking of UDP/53 DNS queries against nameservers that I choose to query from my laptop on Sprint EVDO is not appreciated. Even less appreciated is your complete blocking of TCP/53 DNS queries.
Queries from my lab:
rs@click [14] % dig +short @192.148.252.10 version.bind. chaos txt "Just send your damn query already..." rs@click [15] % dig +tcp +short @192.148.252.10 version.bind. chaos txt "Just send your damn query already..." rs@click [16] % dig +tcp +short @192.148.252.10 hostname.bind. chaos txt "bifrost" rs@click [17] %
Queries from my laptop:
Superfly:~ rs$ dig +short @192.148.252.10 version.bind. chaos txt "9.6.0-P1" Superfly:~ rs$ dig +tcp +short @192.148.252.10 version.bind. chaos txt ;; connection timed out; no servers could be reached Superfly:~ rs$ dig +tcp +short @192.148.252.10 hostname.bind. chaos txt "ns1-kscymar06.spcsdns.net" Superfly:~ rs$
Guys, I send you money each month to deliver packets for me, not to invent new ways of being annoying (and breaking TSIG signed updates to dynamic DNS). Less is more. Please stop dinking with 10-minute-idle TCP sessions (which I complained about a year and a half ago) and knock it off with offering DNS service that I did not ask for.
Sincerely,
Your Disgruntled Customer, RS
PS: No, I don't expect that this open letter will get you to fix the misbehavior, but if some Swedish guy comes along swinging a clue-bat at you guys I hope he whacks you a couple of times for me.
