I am trying to configure a simple email server that uses dovecot for the auth. I am inexperienced with the email procedures and I can't figure out what the problem is here:

postfix/smtpd[26148]: fatal: no SASL authentication mechanisms


My postfix's config file:

tpd_banner = $myhostname ESMTP $mail_name (Ubuntu/GNU)

biff = no



# appending .domain is the MUA's job.

append_dot_mydomain = no



# Uncomment the next line to generate "delayed mail" warnings

#delay_warning_time = 4h



myhostname = localhost

alias_maps = hash:/etc/aliases

alias_database = hash:/etc/aliases

myorigin = $myhostname

mynetworks = 127.0.0.0/8, 10.0.0.0/24

mailbox_size_limit = 0

home_mailbox = Maildir/

virtual_mailbox_domains = /etc/postfix/vhosts

virtual_mailbox_base = /home/vmail

virtual_mailbox_maps = hash:/etc/postfix/vmaps

virtual_minimum_uid = 1000

virtual_uid_maps = static:5000

virtual_gid_maps = static:5000

recipient_delimiter = +

inet_interfaces = all

smtpd_sasl_auth_enable = yes

smtpd_sasl_security_options = noplaintext,noanonymous

smtpd_recipient_restrictions = permit_sasl_authenticated,permit_mynetworks,reject_unauth_destination

smtpd_sasl_type = dovecot

smtpd_sasl_path = private/auth-client

My dovecot config:

auth_mechanisms = plain cram-md5

auth_verbose = yes

base_dir = /var/run/dovecot/

info_log_path = /var/log/dovecot.info

log_path = /var/log/dovecot

log_timestamp = "%Y-%m-%d %H:%M:%S "

mail_location = maildir:/home/vmail/%d/%n

passdb {

  args = /etc/dovecot/passwd

  driver = passwd-file

}

protocols = imap pop3

service auth {

  executable = /usr/lib/dovecot/auth

  user = root

}

service imap-login {

  chroot = login

  executable = /usr/lib/dovecot/imap-login

  user = dovecot

}

service imap {

  executable = /usr/lib/dovecot/imap

}

service pop3-login {

  chroot = login

  executable = /usr/lib/dovecot/pop3-login

  user = dovecot

}

service pop3 {

  executable = /usr/lib/dovecot/pop3

}

ssl = no

userdb {

  args = /etc/dovecot/users

  driver = passwd-file

}

valid_chroot_dirs = /var/spool/vmail

protocol pop3 {

  pop3_uidl_format = %08Xu%08Xv

}

What is wrong with this configuration?

I'm not sure if your socket private/auth-client exists. Try to replace with:
smtpd_sasl_path = private/auth in main.cf.

The problem was that I had to generate a TLS certificate and make dovecot and postfix use it.
The private/auth file will be generated by dovecot automatically after that.
