Can send email to all addresses except clients ending in verizon.net?
I use mozilla thunderbird email application. I am writing to inquire if you may be able to offer me an explanation as to why any emails I send a verizon.net customer do not get received from my business. I am not a Verizon business customer. My ISP is Comcast. My email server is via email.1and1.com. I have checked with them on this issue and they said it is not a 1and1 issue but to contact Verizon. We have done that and they won't talk to us since we are not actually their client. We can send to any and all other emails except customers with verizon.net addresses? We can receive from Verizon.net customers, but when we reply, we hit send and never hear back from customer until we call them and they say they never received the email reply. We also never receive a "delivery failure" notification, thus have no way of knowing whether the emails get through or not. I didn't know if maybe there was some setting in Mozilla Thunderbird that may have accidentally been turned on to "block" Verizon.net customers from being sent to.?? Any help would be appreciated. Thanks!

Do you have an HTML signature that you append to your messages in Thunderbird that was not included when you sent through the web-based interface? Signatures sometimes trigger filters even when the message content is innocent.

I would guess that your messages are falling foul of a spam or AV filter (probably a so-called blacklist) at verizon This could be blocking most if not all email sent by comcast users, or maybe 1and1.com users.
There is an outside chance that your specific IP address is on a blacklist; it's a shame if no-one was able to tell you this, as you could take that information to 1and1 or comcast and urge them to get themselves off the blacklist.
As a test, can you send to a verizon user via your webmail? That is, go to your email account via your browser at the 1and1.com web site.
Email clients don't, generally speaking, self-censor. There is no switch that I know of that would "block" outgoing messages. You might be able to contrive a filter but setting one up would take deliberate and intentional effort on your part.

Okay great. Thank you for the helpful reply. I am looking into all those suggestions and have just sent a few emails using my Internet Explorer browser through and the mail.1and1. site.
One of my verizon.net customers responded to the email I sent them using Internet Explorer and 1and1.com. So that test worked. The email was received on their end, and I got a reply to both my Mozilla inbox and my 1and1 inbox.

No, no signature is used. But Thanks for the input.
