I have a customer that is sending mail that is being marked as spam. It seems to mostly be marked as spam when they are sending to their own domain or another customer that is hosted on the same server. I had shut off spam scanning for both customers, however messages are still being blocked and quarantined. What are my options? I wouldn't mind if I had to shut off spam and virus scanning totally, I have a commercial solution that does that.
Please take a look at the headers of the mail, the reason why the mail is marked as spam is mentioned there.
I cant really help you when you dont post them. You can change the block score in the spamfilter policy, see spam tag 2 level and spam kill level. Then select this policy for the custmer.

I think that will help at least for now. I'll find the headers and post them too. Where do I find the levels to change them?
X-Spam-Status: Yes, score=8.03 tag=3 tag2=6.9 kill=6.9 tests=[DOS_OUTLOOK_TO_MX=2.845, FSL_HELO_NON_FQDN_1=0.001, HTML_MESSAGE=0.001, RCVD_IN_BRBL_LASTEXT=1.449, RCVD_IN_SORBS_WEB=0.77, RDNS_NONE=0.793, SPF_SOFTFAIL=0.665, SUBJ_ALL_CAPS=1.506] autolearn=no
The spf record for the domain seems to be wrong (the mail server that your customers used to send the mail is not allowed according to spf), then your customer used a subject which is completely capitalized, thats uncommon for normal mail but common for spam, the mail server is listed in the Realtime blacklist RCVD_IN_BRBL_LASTEXT, and in SORBS For the DOS_OUTLOOK_TO_MX test: add all your server IP's that are ttrused in the setting "trusted_networks" in /etc/spamassassin/local.cf and restart amavisd afterwards. https://spamassassin.apache.org/full/3.1.x/doc/Mail_SpamAssassin_Conf.html
