I just installed new Discourse (1.7.0 Beta 2 + 8)
For unknown reason I keep getting “[Sender] 501 Syntax error on the mail logs.”
Already checked the following:
- Host name was declared as domain, not using IP.
- separate separate services for posting (pop3) and delivering.
- I am using Hebrew locale, but same issue also when I tried to swtich to English.
Notification email address was defined as firstname.lastname@example.org_subdomain, and did not work also when I tried email@example.com.
