The message code as to why mail is rejected says it's because of rdns, that
I am sending from dynamic IP address. Both of my outgoing ip addresses are
static.

As an aside - Aol and comcast will not reject email just because the rdns
does not match the mail domain name. We have several DSL customers whose
rdns resolves to a generic rdns entry. You might want to try to contact
them to see why they are rejecting your mail.
You can usually only contact them by email but I have found them to
respond usually within a day or two.

Eric,
I am using Microsoft's SMTP service, and it does now allow authentication
when forwarding as far as I can see.
As i've stated I have two connections to my e-mail server,
mail.spectratek.net and mail1.spectratek.net they both revert to the
correct IP address. But when you do a check on the IP address itself, it
shows the name of my ISP instead.
For example IP address mail.spectratek.net is IP address 66.12.134.146.
If I go to whois.sc
http://whois.domaintools.com/66.12.134.146
it shows this:
bdsl.66.12.134.146.gte.net
Who would I go to, to correct the rDNS, Verizon/GTE or my web host?
What MTA do you recommend, so that I can deliver mail thru my web host
SMTP server?
