Hey Edgar,

Thanks for catching that! Missed it earlier! Got it changed but I’m still 
having the same error updated postconf -n:

Why do you provide the Postfix configuration? Absolutely unrelated to the shown 
dovecot error.

I provide what I know how to provide :)

While being at Postfix: You have zero SASL configuration, unless it is defined 
in master.cf for the submission transport.

Lets do 1 problem at a time… Unless SASL is needed for sending email?

Right, 1 problem at a time.

Yes, SASL is needed for your MTA to permit relaying based on authentication.

Here is the same error:

Apr  2 22:25:50 ip-172-31-24-2 dovecot: auth: Fatal: Unknown database driver 
'sql'
Apr  2 22:25:50 ip-172-31-24-2 dovecot: master: Error: service(auth): command 
startup failed, throttling for 60 secs
Apr  2 22:25:50 ip-172-31-24-2 dovecot: imap-login: Disconnected: Auth process broken 
(disconnected before auth was ready, waited 9 secs): user=<>, rip=127.0.0.1, 
lip=127.0.0.1, secured, session=<leZR+ocvhwB/AAAB>

Please provide the output of "doveconf -n". You have a severe configuration 
error so that the auth process fails.

Here is the output:

[ec2-user@ip-172-31-24-2 conf.d]$ dovecot -n
# 2.2.10: /etc/dovecot/dovecot.conf

Where did you get that dovecot version from? The Postfix version seems to indicate a RHEL/CentOS base of major release 6. That one does not ship a dovecot 2.2.x version.

# OS: Linux 4.1.17-22.30.amzn1.x86_64 x86_64  ext4
auth_mechanisms = plain login
mail_location = maildir:/var/vmail/%d/%n/Maildir
mbox_write_locks = fcntl
namespace inbox {
   inbox = yes
   location =
   prefix =
   separator = .
}
passdb {
   args = /etc/dovecot/dovecot-sql.conf.ext

What specified in the dovecot-sql.conf.ext file? Make sure the driver in there is set as "mysql" and not "sql". Not sure whether your dovecot is packaged in a way that you need a another package to provide the SQL driver functionality.

Btw. there is no need to run any SQL based backend, neither for dovecot nor Postfix, while I see a lot of beginners to think it would be. Keep it simple, even most simple while your are doing your first steps.

   driver = sql
}
protocols = imap lmtp
service auth {
   unix_listener /var/spool/postfix/private/auth {
     group = postfix
     mode = 0660
     user = postfix
   }
   unix_listener auth-userdb {
     group = postfix
     mode = 0600
     user = postfix
   }
   user = dovecot
}
service imap-login {
   inet_listener imap {
     port = 143
   }
   inet_listener imaps {
     port = 993
   }
}
service lmtp {
   unix_listener /var/spool/postfix/private/dovecot-lmtp {
     group = postfix
     mode = 0600
     user = postfix
   }
}
ssl = no
ssl_cert = </etc/pki/dovecot/certs/dovecot.pem
ssl_key = </etc/pki/dovecot/private/dovecot.pem
ssl_protocols = !SSLv2 !SSLv3
userdb {
   args = uid=vmail gid=vmail home=/var/mail/vhosts/%d/%n
   driver = static
}
protocol lmtp {
   mail_plugins = " sieve"
}
protocol lda {
   mail_plugins = " sieve"
}
[ec2-user@ip-172-31-24-2 conf.d]$


It’s been awhile since I’ve run a mail server, and never to this extent… Always 
through hosting companies except for about 15 years ago when I did it for fun! 
:)

Thanks for all your help!

Regards

Alexander
