I am running vestacp on ubuntu. Encountered i) phpmyadmin pma issues when importing db. ii) roundcube unable to save password. iii) emails sent to gmail ended up in spam folder. iv) DKIM check: permerror. All 4 issues above were solved with help from google for the fix.
The smtp mail check using mxtoolbox lastly showed 550: relay permitted for my vestacp installation. A check on another smtp mail from cpanel showed
550-Please turn on SMTP Authentication in your mail client, or login to the 550-IMAP/POP3 server before sending your message. pws3.mxtoolbox.com 550-[220.127.116.11]:63195 is not permitted to relay through this server without 550 authentication. [703 ms]
Does that mean I am accepting emails which have not be authenticated? If yes, how do I configure exim4 to show the new message/rule in code 550?
