[CGUYS] Verizon smtp and Port 25
I have Cox Cable Internet Access in Annandale (VA). Cox blocks Port 25 usage for all smtp servers except Cox itself, so that all outgoing e-mail messages from any sender address have to use Cox's smtp server (smtp.east.cox.net). They do this, apparently, so they can easily detect spammers on their own circuits. Can anyone tell me whether Verizon FIOS (or DSL) service does this? (in Annandale / northern VA) Thanks, Fred Holmes * ** List info, subscription management, list rules, archives, privacy ** ** policy, calmness, a member map, and more at http://www.cguys.org/ ** *
Re: [CGUYS] Verizon smtp and Port 25
A quick google and it looks like it's blocked, I'd be surprised if it wasn't, those big guys don't want anyone running a server on their network.

Nope, they block 80, but not 25, thank goodness. mike xha...@gmail.com wrote: A quick google and it looks like it's blocked, I'd be surprised if it wasn't, those big guys don't want anyone running a server on their network.

Re: [CGUYS] Verizon smtp and Port 25
No, I'm not running a mail server. I need to help someone set up his/her mail client for a third party POP/SMTP mail account, and he/she is connected via Verizon (dunno if FIOS or DSL, but I presume FIOS). I'm trying to find out what to expect, although a quick test should make it obvious. I.e., in entering the address for the smtp server, do I enter the address of the third-party host of the mail server in question, or do I enter the address of Verizon's smtp server?

Yes, I do run a mail server using Linux. mike xha...@gmail.com wrote: Are you running a mail server?

Re: [CGUYS] Verizon smtp and Port 25
Port 25 is often blocked for security reasons. For SMTP, we've been using port 465 SSL for smtp.correo.yahoo.es, port 465 TLS for smtp.gmail.com, port 587 TLS for outgoing.verizon.net. I can send from any of my email accounts through all three, but the gmail SMTP server renames the sender with my gmail address, the others don't. Examples: * I send an email with a Yahoo! address using the Verizon SMTP, no problems. * I send a message with a Verizon email address using Yahoo! SMTP, no problems. * I send a message with a Verizon email address using GMail SMTP and it arrives with a GMail address instead of Verizon.

Re: [CGUYS] Verizon smtp and Port 25
Thanks. I've been doing that for several years now, since before I got Cox HSI access. I'm just trying to figure out what to expect when setting up someone else who subscribes through Verizon.
