Hello,
I want to use different authentication arguments for smtp and imap/pop3.
In the dovecot list I found this:
http://www.dovecot.org/list/dovecot/2013-August/091960.html
I tried to follow these instructions but dovecot refuses to find the
auth executable:
Dec 12 10:36:18 jlaptop postfix/smtpd[7302]: connect from localhost[127.0.0.1]
Dec 12 10:36:18 jlaptop dovecot: auth-10: Error: doveconf: Fatal:

or directory

command startup failed, throttling for 2 secs
Dec 12 10:36:18 jlaptop dovecot: auth-10: Fatal: master:

Dec 12 10:36:19 jlaptop postfix/master[7046]: warning:
/usr/lib/postfix/smtpd: bad command startup -- throttling
My settings for postfix and dovecot are as follows:
root at jlaptop:/usr/local/etc/dovecot/conf.d# postconf -n
alias_database = hash:/etc/aliases
alias_maps = hash:/etc/aliases
append_dot_mydomain = no

smtpd_sasl_auth_enable = yes
smtpd_sasl_path = private/auth-10
smtpd_sasl_type = dovecot

auth_debug = yes
auth_debug_passwords = yes
auth_verbose = yes
first_valid_uid = 124
mail_gid = mail
mail_home = /var/mail/imap/%n
mail_location = maildir:~/mail
mail_plugin_dir = /usr/local/lib/dovecot/
mail_plugins = gpgfuse_umount
mail_uid = vmail
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 }
passdb {
args = session=yes dovecot
driver = pam
}
protocols = imap pop3 lmtp imap pop3
service auth-10 {
executable = auth -c /usr/local/etc/dovecot-auth-smtp.conf
process_limit = 1
unix_listener /var/spool/postfix/private/auth-10 {
group = postfix
mode = 0666
user = postfix
}
}
ssl_cert = </etc/dovecot/dovecot.pem
ssl_key = </etc/dovecot/private/dovecot.pem
userdb {
args = uid=vmail gid=mail home=/var/mail/imap/%n
driver = static
}
The file /usr/local/etc/dovecot-auth-smtp.conf is as follows:
auth_mechanisms = plain login
disable_plaintext_auth = no
#auth_username_format = %Lu
auth_debug = yes
auth_debug_passwords = yes
auth_verbose = yes
first_valid_uid = 124
mail_gid = mail
mail_uid = vmail
protocols = imap pop3 lmtp imap pop3
ssl_cert = </etc/dovecot/dovecot.pem
ssl_key = </etc/dovecot/private/dovecot.pem
passdb {
driver = pam
args = dovecot
}
userdb {
driver = static
args = uid=vmail gid=mail home=/var/mail/imap/%n
}
The result is exactly the same also if I don't give the path to auth. I.e.:
executable = auth -c /usr/local/etc/dovecot-auth-smtp.conf
In order to get past this problem I provided the auth executable in
/usr/local/var/run/dovecot/dovecot/auth, but then I get a new problem:
Dec 12 12:31:53 jlaptop postfix/smtpd[9220]: connect from localhost[127.0.0.1]
Dec 12 12:31:53 jlaptop dovecot: auth-10: Error: Debug: Loading

Dec 12 12:32:04 jlaptop postfix/master[8842]: warning:

My test client is thunderbird with smtp connection security "None" and
Authentication method "Password, transmitted insecurely".
Any ideas what is going wrong? Is there a better way to provide
different passdb settings for smtp and imap/pop3?
