	I can find these logs, but they don't include any proxy_timeout option, 
all of them are like:

Jun 18 08:26:26 myotis41 dovecot: lmtp(640): Debug: auth input: 
user=<user> proxy host=155.54.211.164 proxy_refresh=450

	But I have found, I think, the problem... I had configured 2 user backends:

!include auth-master.conf.ext
!include auth-ldap.conf.ext

	The first for master password, and the other, to get users from a ldap 
directory. In my auth-ldap.conf.ext I changed the ldap driver for passdb 
to static (I can't check user password in the director for other 
reasons), so I had:

passdb {
   driver = static
   args = proxy=y nopassword=y
}

userdb {
   driver = prefetch
}

userdb {
   driver = ldap
   args = /etc/dovecot/dovecot-ldap.conf.ext
}

	so, although in the dovecot-ldap.conf.ext I have:

pass_attrs = 
irisMailbox=userdb_mail,homeDirectory=userdb_home,uidNumber=userdb_uid,gidNumber=userdb_gid,=proxy=y,=proxy_timeout=120,irisMailHost=host

	it seems that it isn't used and proxy_timeout it's not defined.

	So I have changed passdb definition to be:

passdb {
   driver = static
   args = proxy=y nopassword=y proxy_timeout=120
}

	and now logs are like:

Jun 18 08:46:18 myotis40 dovecot: lmtp(11276): Debug: auth input: 
user=<user> proxy proxy_timeout=120 host=155.54.211.169 proxy_refresh=450

	Is this correct?
