I've been running postfix with cyrus-SASL for years but it's time to
change the SASL tool to dovecot. I've been wrestling with this for a couple
of days now and it has me pinned to the mat. I need help.
Today I upgraded dovecot-2.2.13 to -2.2.15. Went to the dovecot Web sits
and followed the configuration instructions step-by-step. Added user
dovenull and all checks appear correct:
doveconf -n
# 2.2.15: /etc/dovecot/dovecot.conf
# OS: Linux 3.10.17-smp i686 Slackware 14.1 ext3
mail_location = mbox:/var/spool/mail/%d/%1n/%n:INDEX=/var/indexes/%d/%1n/%n
namespace inbox {
inbox = yes
location =
mailbox Drafts {
special_use = \Drafts
}
mailbox Junk {
special_use = \Junk
}
mailbox Sent {
special_use = \Sent
}
mailbox "Sent Messages" {
special_use = \Sent
}
mailbox Trash {
special_use = \Trash
}
prefix =
type = private
}
passdb {
args = scheme=CRYPT username_format=%u /etc/dovecot/users
driver = passwd-file
}
ssl_cert = </etc/ssl/certs/dovecot.pem
ssl_key = </etc/ssl/private/dovecot.pem
userdb {
args = username_format=%u /etc/dovecot/users
driver = passwd-file
}
In postfix's main.cf:
smtpd_sasl_path = smtpd
# Frontier blocking outbound port 25:
relayhost = [mail.aracnet.com]:submission
smtp_sasl_auth_enable = yes
smtp_sasl_password_maps = hash:/etc/postfix/sasl_passwd
smtp_sasl_security_options = noplaintext, noanonymous
smtp_sasl_tls_security_options = noanonymous
smtp_tls_security_level = may
smtp_sasl_type = dovecot
#smtp_sasl_type = cyrus
All looks good, so I start postfix (/etc/rc.d/rc.postfix start) and tail
/var/log/maillog where I see this:
Feb 17 15:03:13 salmo postfix/smtp[30653]: warning: unsupported SASL client
implementation: dovecot
Feb 17 15:03:13 salmo postfix/smtp[30653]: fatal: SASL library
initialization
Feb 17 15:03:14 salmo postfix/master[30558]: warning: process

Feb 17 15:03:14 salmo postfix/master[30558]: warning:
/usr/libexec/postfix/smtp: bad command startup -- throttling
The problem looks like it's with postfix, not dovecot, but my inexperience
prevents me from seeing what it is. Please provide a clue so I can move past
this issue.
TIA,
Rich
