POP email from China not able to send in home Verizon network

Hey guys,

I have one user from china, with an email account from china.  Using his tablet for emails, If he is in inside Verizon home network, he can only receive emails, and NOT ABLE to SEND emails.

Hello,

Verizon is likely blocking port 25. You can test this by opening a command prompt and typing:

telnet <smtp server> 25

Replace <smtp server> with the smtp server in his email client's settings.

You should get a banner response from the server. If you can't connect, port 25 is blocked.

jjmck,

Something that I forgot to mentioned, we did run port scan on the router, all is good. No blocking, and it was working before that.
John Hurst,

We will try your recommendation.
John Hurst,

Wait, John this is a tablet, it is configured using POP.
I use POP and I need to authenticate off my home network. Almost any email tool has these settings so take a look at the settings and try.

There may be something else blocking the mail in and out of China, so the above is just a possible solution.
Great, will try this tonight.
He needs to have a verizon account to use their SMTP server, but the settings are available here: http://www.verizon.com/Support/Residential/Internet/highspeed/email/setup+and+use/questionsone/86782.htm#

Most ISPs block port 25 for home users in the US now to reduce spam. If he doesn't have a Verizon account to authenticate against their SMTP address, he will probably need to talk to whoever provides his email and see if they have an authenticated/alternate port SMTP port available.
@tomfontanilla - Thank you and I was happy to help.
No, thank you for your help!
