[Mailman-Users] Mailing List Bounce Problems

The mailing list archive issue that I was inquiring about is a pretty low-volume list. When looking into the archive problem, i saw there were some messages listed in /var/lib/mailman/logs/post that I never received. When looking at the member list, most of my list members were no longer receiving emails due to excessive bounces. I have it set to notify the admin (my gmail account) when a user is disabled, but I've never received a notification. I enabled notification when a message I send to the list is sent out, and I receive that notification, but nobody receives the message. Admin emails from mailman go through just fine, but any message posted to the list does not. I have an IMAP email account on the same server which hosts the mailman instance, and it seems to get all my test messages that I post just fine, but all yahoo, windstream, gmail, etc get bounced.
an example line from the /var/log/mail.info file is:
Sep 10 12:49:21 bunsen postfix/smtp: 0DF621C375: to=<web-p6036h at mail-tester.com>, relay=mail-tester.com[220.127.116.11]:25, delay=2.6, delays=0.03/0.07/0.86/1.6, dsn=5.0.0, status=bounced (host mail-tester.com[18.104.22.168] said: 550 Message Contains SUSPECT Content :: Please contact abuse at fortressitx.com for further information. (in reply to end of DATA command))
I've been using the services at mail-tester.com to ensure that my domain keys, DMARC, and SPF are all set well. You can see those results here (http://www.mail-tester.com/web-p6036H).
I deleted the entire mailing list after exporting the 114 email address, and remade the list, and it behaves the same.
The odd thing is, I have another mailing list on the same server with only 6 members, and it seems to be working fine!
Any clue where to look? I've contacted abuse at fortressitx.com and received no reply.
