The email headers from your message indicate the following:
Received: from mail.web-partners.com [206.190.82.18] by list.ipswitch.com with ESMTP
A DNS lookup of [206.190.82.18] shows a **NON MATCHING** PTR of: "PTR, 206-190-82-18.static.twtelecom.net". Many providers will DEVNULL email from systems that fail on PTR lookups.
Your domain, web-partners.com, also does not have a SPF record. Not having a valid PTR (big / huge strike) and no SPF record ( minor / large strike) could be reason(s) enough for companies to reject your email.
Here is a link to the SPF wizzard that will help you add SPF records to your DNS zone.

As with any link in email, copy and paste the URL do not click on it.
Cheers (and good luck),
Greg.

Guys
I'm desperate,
Now we can't send to get.net also.
And of course I can't contact anyone at verizon.
Does anyone have a Verizon contact number? I can't send them email, so I'm
really out on a limb.
Thanks John

>>Morning all

>>Last week, I found I was unable to send to a Verizon customer. I
>>was getting "550 You are not allowed to send
>>mail:sv5pub.verizon.net"
>>I submitted our mail server IP address to see if we were
>>blacklised and got a reply back that we were not.
>>I then switched to using a Charter SMPT server and got a similar

>>I next tried using remote access, web mail on the our Imail
>>server so there would be no record of a dynamic IP address in the
>>header and sent another message.
>>It timed out this morning with "421 SMTP service not available,
>>closing transmission channel" and terminating after the Imail max
>>tries timed out.
>>
>>Does anyone have any thoughts, as we speak, none of our customers
>>are now able to email anyone at Verizon.
>>
>>Thanks for any help.
