All MaxBulk email Caught as "spam" by servers

[choho]

I am able to send from Mac Mail but not from MaxBulk Mailer. Have been using the program, same outgoing server (fatcow), and ISP (AT&T) since 2003 without problem. Last used MaxBulk Mailer sucesseffully in July 2008. This month I cannot send my email. Even test mail from my fatcow account to my fatcow account do not reach my computer but a check via my webmail account shows the mail to be stuck in the Fatcow Spam box (not even reaching my computer Mail spam box). None of my 1600 reciepients recieved the mail as well. Settings for MaxBulk mailer have not changed since July. Settings as follows: SMTP server= smtp.fatcow.com:587, connections =2, account [email protected], delivery=singly, group mails= 15, Interval=None, sender [email protected].

Both my domain hoster(fatcow) and my ISP (AT&T) have different opinions as to the problem. See below..

RESPONSE FROM FATCOW:
"After looking over the headers of one of the e-mails in you spam folder (TEST:July email with video embedded) it appears that the IP address that you have been issued by your ISP is on multiple spam blacklists. The IP address listed in the headers is 71.139.34.244. According to http://openrbl.org/client/#71.139.34.244 that IP address is listed on the FiveTen and S.O.R.B.S. blacklist. Please contact your ISP and have them remove your IP address from those blacklist or have them issue you a new IP address."

RESPONSE FROM AT&T:
You are assigned a dynamic address everytime you connect. You cannot therefore be on blacklists everytime. Fatcow may have problems identiyfing a dynamic address when you use their outgoing server. You should therefore pay extra from us (AT&T) so we can assign a static IP address to your account.

MY THOUGHTS:
MY problem is not sending any mail. Mac Mail is also configured to use Fatcow as the outgoing server and it works fine. My problem is only sending with MaxBulk Mailer, even small tests to 2 addresses. Also tried disconnecting my router & sending directly from computer to no avail. I have not changed anything since last sucessful use (July) yet I cannot send this month. Today I even tried upgrading from MaxBulk Mailer 4.1 (ish) to 4.4.4. I am stumped.

I can attach the email in question if that would be useful. The email is our standard: an HTML email and it contains an embedded google video. My sucessful July email also was an html email with embedded google video so I don't think that is the problem.

Many, many thanks.

resolved

after reading someone else's tip (do not cut & paste html code into email) I was able to isolate the problem. I had used an "addthis" share button. Without that feature, the email did not get stuck in server junk boxes, with the "addthis" button it did get caught. My work around? I changed the "addthis" url to a tinyurl with the same info and presto, email was sent to my 1600 person list.

sweet.
