Outgoing messages blocked by some recipients due to Spamhaus PBL

Question

I've read some related issues about this on the forums, but I haven't found any helpful solutions.
I am a FiOS customer, but I already have email service set up with other providers, and have no interest in changing my e-mail address(s). In general this works fine.
Recently however I have found that some receipients, who use spamhaus, are blocking my messages - apparantly because Verizon said that the only way their clients are allowed to send e-mail is through their servers.  The bounce looked something like this (personally identifying information, etc. edited):

 When reading the information at Spamhaus, I said OK, sounds like I need to use a verizon.net server.  So I set my outgoing server to outgoing.verizon.net, with appropriate credentials (I do have a verizon.net e-mail address, I just don't use it).  This seemed to work, but today when sending to the same recipient, I got the following bounce:

Now first of all, I find it unacceptable that I need to use Verizon's outgoing mail servers rather than the provider of my choice.  This means that if I have someone over who wants to connect their laptop to our network to send e-mail, they have to reconfigure their e-mail, and I have to give them my credentials, or else create an account for them on verizon.net.  That's just bizzare!
But now it seems that Verizon is also not even keeping its own data straight with spamhaus!
Can anyone shed any light on this?  Is there anything I can do to resolve these problems?
Thank you all!

Answer 1

You don't need to change your INCOMING email address however you do need to change your outgoing email server address to be the Verizon server.  If you don't do this your email may be refused and treated as spam because it will appear that you are using "relaying" to send mail from fake accounts.
You now appear to have hit the other problem that sometimes occurs.  It seems that at some point in the past the dhcp address you recived from verizon was blacklisted for something and spamhaus is now rejecting the email.  The simple answer to this is to reboot your verizon router to get a new address.  You could then report the blacklisted address to Verizon who might fight the adress issue with spamhaus or you could di it yourself.  Think I had this occur 3 times in the 5 years I had Verizon dsl on a pppoe connection which delivers dhcp address changes many more times than FiOS does.
