Postfix, Dovecot and SASL: SASL not present

Postfix, Dovecot and SASL: SASL not present

It seems that I don't have SASL support, althou I've checked my
configuration against ALL the online tutorials, and it seems fine to me.
I've also checked /var/log/mail.log and there's no word "SASL" in it.
telnet localhost 25
Trying ::1...
Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.
220 GOD
ehlo localhost
250-mail.local
250-PIPELINING
250-SIZE 30720000
250-VRFY
250-ETRN
250-STARTTLS
250-ENHANCEDSTATUSCODES
250-8BITMIME
250 DSN
While it should also spit out something like this:
250-AUTH NTLM LOGIN PLAIN DIGEST-MD5 CRAM-MD5
250-AUTH=NTLM LOGIN PLAIN DIGEST-MD5 CRAM-MD5
The SASL daemon is up:
ps aux | grep sasl
root 10219 0.0 0.2 77836 2368 ? Ss 04:56 0:00
/usr/sbin/saslauthd -a pam -c -m /var/spool/postfix/var/run/saslauthd
-r -n 5
The file /etc/default/saslauthd seems ok:
START=yes
NAME="saslauthd"
MECHANISMS="pam"
THREADS=5
OPTIONS="-c -m /var/spool/postfix/var/run/saslauthd -r"
Permissions for /var/spool/postfix/var/run/saslauthd look ok:
ls -l /var/spool/postfix/var/run/saslauthd
-rw-rw---- 1 root sasl 0 Aug 22 04:56 cache.flock
-rw-rw---- 1 root sasl 986112 Aug 22 05:08 cache.mmap
srw-rw---- 1 root sasl 0 Aug 22 04:56 mux
-rw-rw---- 1 root sasl 0 Aug 22 04:56 mux.accept
-rw-rw---- 1 root sasl 6 Aug 22 04:56 saslauthd.pid
The user postfix is part of group sasl:
getent group sasl
sasl:x:45:postfix
The /etc/postfix/sasl/smtpd.conf looks good:
pwcheck_method: saslauthd
mech_list: plain login
allow_plaintext: true
auxprop_plugin: mysql
sql_hostnames: 127.0.0.1
sql_user: mail
sql_passwd: mail
sql_database: mail
sql_select: select password from users where email = '%u'
