Up until yesterday the following was providing Postfix SMTP client SASL
TLS authentication with my email provider's outgoing email
server (configs have been sanitized for public posting):
#/etc/postfix/main.cf
myhostname = beasty.sleepy.cat
mydomain = sleepy.cat
smtp_generic_maps = hash:/etc/postfix/generic
mynetworks_style = host
alias_maps = hash:/etc/mail/aliases
relayhost = [smtp.acme.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 = saslc
#../generic
m...@beasty.sleepy.cat m...@acme.com
#../sasl_passwd
[smtp.acme.com]:submission m...@acme.com:secret_passwd
Did chmod 600 for the sasl_passwd file and ran postmap(8) run on generic
and sasl_passwd for DB file generation, then checked with 'postfix check',
then reload configs with '/etc/rc.d/postfix reload'.
Anyway, something has changed sometime since my previous -current update
dated ~May 2015; after upgrading to -current dated Aug 22, 2015 the above
configuration no longer works.
Below appears to be the pertinent bits from /var/log/maillog; date prefix
removed for clarity:
..

to=<some...@somewhere.com>, relay=none, \
delay=1.4, delays=0.16/1.2/0/0.07, dsn=4.3.0, \
status=undeliverable (unknown mail transport error)
I'm hoping someone can point me towards a solution or work-around
so I can go back to using the native tools for mail relaying.
