I’ve used MXRoute for 10 months without issue, but starting last month my email is going straight to junk for O365/Outlook users, and I’ve just had an email rejected by a large firm.
SPF record is correct.
mxtoolbox shows: No DMARC Record found and DMARC Quarantine/Reject policy not enabled
Not sure if that is related.
Here is the rejection from PCLaw support
Remote-MTA: dns; us-smtp-inbound-2.mimecast.com
Diagnostic-Code: smtp; 554 Email rejected due to security policies - https://community.mimecast.com/docs/DOC-1369#554 [qPnCXjz9MlW-wMKa9w_Xyw.us107]
Is the “friday” SMTP server being rejected? please help!
