Re: Has COVAD just started Port 25 blocking?
said by rtfm8  :Suddenly I can't get outgoing Port 25 connectivity. That would be a question to ask your ISP since they determine what features that you have available and whether or not you have filtered outbound/inbound ports. Covad is not your ISP, AT&T WorldNet is.
This appears to be the Forum below.
»AT&T DSL Service
said by rtfm8 :I got no notice or warning on this. Did you check the AT&T WorldNet TOS and AUP pages? You are responsible to read them and they state that is where all changes will be published.
said by rtfm8 :And no, I'm not a spammer, and have no Windoze boxes to be turned into Zombies, etc.... And it is not a factor if you are or if you are not. They rarely block one person, they change the Border/Gateway Routers to drop your outbound port 25 requests allowing you only access to the WorldNet SMTP servers on the outbound direction. You simply change your eMail clients to the AT&T WorldNet SMTP servers and are back in business. If you are running your own SMTP locally, then you set that up to smart host into the WorldNet SMTP servers and you are done.

1 edit | Not sure I ever said the ATT account was mine; it's not. It's one I got working....
Again, this is a covad.net account; with bills from covad, an email address at covad [if I wanted such..] and so forth.
ATT has zero involvement AFAIK. |

How do we determine *any* of this info based on what you ~initially~ posted?
You did not say, "I'm working on a Covad Line for someone with Covad service". You posted in first person like this was your line and we can only go by your listed ISP then.
Plus why would you say "I got no notice or warning on this." if this was not your line?? Normally you would say I checked with the owner of the service and they tell me they have not gotten any change notices or seen any TOS/AUP changes on their Covad Account.
See how you make it very difficult for others to even begin to help you?

1 edit | Funny you should mention that tag under my login. I looked for 30 minutes yesterday trying to grok where it is [un]set. It's not in Site Preferences or Account Settings.
I apologize that it confused some folks. This is a covad.net account; my current IP is in the 67.103.25.xx block.
Here's two examples of the blocking, and one from a shell host in NYC to show how it should look.
As for the T&C's, here's a quote from the site:
quote:
Although Covad's servers will allow SMTP Relay, it is not advised. A valid covad.net email account must be set up in the SMTP setup of the mail client. Because covad.net email accounts are consumer accounts and are designed for general home consumer use, many customers using SMTP relay for their business needs may violate Covad's Acceptable Usage Policy, which we advise you to review. Covad does not block port 25 in through the network. It is advised that instead of using SMTP relay, customers use their provider's SMTP server for sending third party hosted mail.
From what you are collectively saying; I'm the only one seeing this issue, so I guess I'll see what the covad direct group says.
Thanks for the input. |

You can't "unset it", you have to review your current ISP/Provider if you are no longer using AT&T and that new ISP/Provider review will replace it.

It is interesting that your failed port 25 telnet sessions report "Unable to connect to remote host: No route to host". When I try to do a port 25 telnet session from my Covad circuit to a BellSouth/AT&T mail server that implements port 25 blocking to off-net access, the reply I get is "connect to address 207.115.11.17: Connection timed out" from Linux, and "Could not open connection to the host, on port 25: Connect failed" on Windows.
The Linux console session below shows that the host "mail.bellsouth.net" is indeed blocked for port 25, but it can be connected using port 110, and also pinged.
When I try the same connection sequences from my BellSouth/AT&T circuit (which does have a port 25 off-net block) to "mail.panix.com" and "dc-sage.org", I get the "Connection timed out" and "port 25: Connect failed" messages for port 25 attempts, not a "No route to host" reply. I had no problems establishing port 25 or port 110 sessions to either of those hosts using my Covad circuit.
Can you reach "mail.panix.com" and/or "dc-sage.org" using a port 110 telnet session, and can you ping them?

And yes, they ping as well.
