This is an interesting move. Presumably this is because more and more _residential_ users are switching to a web-based mail system like hotmail and gmail. Leaving the bulk of the smtp traffic to be spam sending malware.<div>
<br></div><div>Does this service effectively prevent the use of a native smtp client or does it just prevent the client from using other smtp servers besides Qwest's? I would guess that qwest would allow users to continue using the qwest mail server. However the problem I've always run into is that if you're using a mobile device then you can't send mail unless you're at home, on the ISPs network.</div>
<div><br></div><div>A few years ago Verizon's residential DSL service in Florida had a different policy. They declared all smtp traffic to be for businesses and residential users weren't allowed to make SMTP connections to any server except theirs unless you upgraded to the business DSL package. Do you think this is the motivation of Qwest?<br>

Not sure if anyone else ran into this, but it had me vexed all week. I have used thunderbird for years from home to relay off an outside server and it just quit working and starting giving an error about SMTP timeout.<br>
<br>
Turns out Qwest has done some sort of subtle blocking of port 25 that causes SMTP to timeout, although the port appears to be open (you can telnet to it).<br>

A call to tech support got them to drop the filtering within a few minutes and my email works again.<br>
