sorry for replying through that links but - as you may see - replying to Jonathan will not work.

If AT&T have such strange policy then i am just sorry. It sings the beginning of end of open internet if more companies will start to do this, and result in few huge corporations handling everything.

Not happy world to live.

For Jonathan Ryshpan:

for no obvious reason my IP is blocked at AT&T mail server you use.

I'm not sure what's going on, but I suspect the problem is this: Many US mail servers refuse to accept mail from any servers that they have not approved; if mail is coming direct from you to ATT, rather than via some large ISP, it will likely be refused. This is supposed to reduce the amount of spam (fat chance).

Thanks for your reply - jon
