What in the HELL happened?????

I pulled an all-nighter last night. I had been e-mailing and uploading fairly big files sporadically over the course of a few hours. Suddenly, I was unable to send or receive e-mail. The program kept trying to send, but no go.

My internet connection was fine.

This morning I call our company server provider to find out what's up.

"You have FIOS, right?"

"Yup."

"That's your problem. They're blocking your outgoing mail from coming to our servers. They also changed a port for inbound traffic."

While all of that is Geek or Greek, or whatever, to me, the essential truth is that Verizon wants to make sure no one misbehaves on their network - or so the story goes. He advised me to change my outgoing mail server back to Verizon and change my incoming port to (whatever he said). Voila! It all works.

Two weeks ago, FIOS took back my static IP addresses (needed by some office machines we have). Now they take away my mail server.

What the hell is going on????

Brian Krebs in the Washington Post has it from Verizon that they will be following most of the rest of the industry in blocking port 25 e-mail submission soon. Users will have to do SMTP e-mail submission with port 587 which requires authentication.

Krebs notes that Verizon is the #1 US ISP on Spamhaus's CBL, a list of services with addresses that have been observed sending spam; almost 1/4 of the US addresses in the list are on Verizon's network. Other large providers on the list have far fewer such addresses.

Verizon spokesman Clifford Lee told Krebs that the shift will begin within the next few months. People who use webmail won't have to change anything, but users of e-mail clients like Outlook, Outlook Express, Eudora and Thunderbird will have to make some configuration changes. Verizon will be contacting users with instructions.


Sorry but the blame lies on those fucking spammers. Most ISP's are just trying to make it harder for them and you also.

Been that way for years. 90% of the spam I get has either a yahoo or gmail address.

And he only gets four years at the country club. If they made these guys do serious time in hard core prison maybe spam would slow down.

and Gitmo would be too good for the malware clowns.

the port 587 does not in and of itself require authentication...the email server is the only point at which authentication is required or not. use of port 587 connects to a port on the email server which requires authentication...you can technically use any port that the email server is configured to accept connections from.

other than that...yer spot on!
