Topic: iRedmail stopped sending mails
Kindly assist me in resolving this problem; the iRedmail server suddenly stopped sending mails. That is, I could not send mails from any user account anymore.
Looking at the mail log, I found this:
May 3 16:50:24 mail postfix/smtpd[3010]: warning: mail.x.x.x[127.0.0.1]: SASL LOGIN authentication failed: Invalid authentication mechanism
May 3 16:50:24 mail roundcube: Invalid response code received from server (535):
