Does your ISP block port 25?
 

Fuckin Cox High Speed Access

Q: Why didn?t Cox notify customers that it would begin blocking all network traffic from residential customer IP addresses going outbound on port 25 (SMTP) at Cox?s routers (unless it is being sent to a Cox HSI SMTP server)?

A: Port 25 is on Cox?s blocked list as noted in the Subscriber Agreement and in information found on our support site. This information is available to customers at all times, and customers are instructed to routinely check the Policy for information on acceptable uses of the service and network. The current blocking of Port 25 does not reflect a change in our policy, but rather an enforcement of said policy for the benefit of all Cox High Speed Internet customers. This effort is mean to reduce unsolicited bulk e-mail sent on our Cox High Speed Internet network.

I had problems with that, too.

ARe you using a desk top system? Or on your own server??

They're blocking standard outbound email through port 25, or whatever it is.

sly_rj what are u doing about it

My outbound mail goes through a company called Net Identity. I checked their trouble shooting pages and they helped me verify that it was my ISP causing the trouble. Their site also showed me how to send email through another available port. I guess it depends who you do your email with, but I would check with them for possible solutions.

whats their URL?

www.netidentity.com

It's just a basic POP3 service, like $15 a year. I've had this email address for over 6 years, so I just stick with it.

A simple solution would be to set up an SMTP relay at your site (Phatservers) on a non-standard smtp port (other than 25), like 8025. Then you could send outbound smtp from your desktop via your Cox cable modem without being blocked. You would have to set up your mail client to use the non-standard port. After receiving mail on the non-standard port, your SMTP relay would then forward the mail on SMTP port 25. If Cox persists in blocking outbound 25, it's your only option, unless you use their SMTP relays or some kind of webmail.

Cox can go fuck themselves. :feels-hot

You can just use them as your outbound smtp..

Thats what I had to do..

yea that was my next option.. hit me up i wanna discuss something with you fudd

Yay, ISP's for dummies.

I'm running everything from web to mail to DNS servers for my home network right from the house. Hell, my ISP serves as my *secondary* DNS; they don't block shit, if they did I'd be looking for a real ISP to do business with.

The cable companies are great for the Counter Strike kidz but not if you need to do any real work.

I have the same problem here with ALL the ISP's in the area. I ended up just sending my email through my server on a non-standard port that they are not blocking. I have no choice because All the ISP's are doing the same thing. I hope they don't find the port I am using and block it also. They should just look at there logs and stop the :ak47: spammers and not mess with someone trying to send normal emails.
