I'm trying to set up an email server on Centos 7 using postfix and dovecot.
whenever I telnet into my server, I get kicked out:
[root@mail log]# telnet mail.mydomain.com smtp
Trying IP ADDRESS...
Connected to mail.mydomain.com.
Escape character is '^]'.
Connection closed by foreign host.
When I check the logs in /var/log/maillog this is the error I see:
Mar 15 05:33:44 vultr postfix/smtps/smtpd[20434]: connect from ***********
Mar 15 05:33:44 vultr postfix/smtps/smtpd[20434]: warning: SASL authentication failure: Internal Error -4 in server.c near line 1757

Any help would be appreciated, thank you.
