Still muddling through with broken auth...

Hey Everyone,

I’m still muddling through my first install… Followed the tutorials on <> which were very helpful! but don’t include much info if things don’t work 100%… and so far I haven’t been able to pin down where the error is. When I try: telnet localhost 143 this is what shows up in the maillot:

Apr  2 21:06:57 ip-172-31-24-2 dovecot: auth: Fatal: Unknown database driver 'sql'
Apr  2 21:06:57 ip-172-31-24-2 dovecot: master: Error: service(auth): command startup failed, throttling for 2 secs
Apr  2 21:06:57 ip-172-31-24-2 dovecot: imap-login: Disconnected: Auth process broken (disconnected before auth was ready, waited 0 secs): user=<>, rip=, lip=, secured, session=<+lw34IYvVgB/AAAB>

With the failed driver for the database, I tried mysql and sql both of which produce the same error… I have a few other issues but I think those are related farther upstream… Not being able to sign into round cube for webmail, because of it being unable to connect to the storage container… But I think that’s a round cube issue… I want to get postfix and dovecot playing nicely before I worry too much about things like webmail access…

Here is my postconf -n:

[ec2-user at ip-172-31-24-2 dovecot]$ postconf -n
alias_database = hash:/etc/aliases
alias_maps = hash:/etc/aliases
command_directory = /usr/sbin
config_directory = /etc/postfix
daemon_directory = /usr/libexec/postfix
data_directory = /var/lib/postfix
debug_peer_level = 2
html_directory = no
inet_interfaces = localhost
inet_protocols = all
mail_owner = postfix
mailq_path = /usr/bin/mailq.postfix
manpage_directory = /usr/share/man
mydestination = $myhostname, localhost.$mydomain, localhost
newaliases_path = /usr/bin/newaliases.postfix
queue_directory = /var/spool/postfix
readme_directory = /usr/share/doc/postfix-2.6.6/README_FILES
sample_directory = /usr/share/doc/postfix-2.6.6/samples
sendmail_path = /usr/sbin/sendmail.postfix
setgid_group = postdrop
unknown_local_recipient_reject_code = 550
virtual_mailbox_domains = hash:/etc/postfix/virtual_mailbox_domains
virtual_mailbox_maps = hash:/etc/postfix/virtual_mailbox_users
virtual_transport = dovecot
[ec2-user at ip-172-31-24-2 dovecot]$ 

What else can I provide?
