postfix outbound forwading?

Hey all,

I just bought a mailhop outbound form dyndns.org because some ISP's would not accecpt my e-mails. (I am in a residential zone) So I am wondering how to set up postfix to push mail out to dyndns.org.

I also need to supply there smpt server with a username and passwd And would like to enable SSL. Can I set up postfix to do this for me, if so how?

Thanks

yes you can use smtp authentication in postfix... you need to install cyrus-sasl and configure your smtpd.conf file in /usr/lib/sasl to use whatever auth methods you want... plus you need to add these lines in the /etc/postfix/main.cf file to be able to auth properly (and run /etc/init.d/postfix reload after you make these changes)

#allows for general auth
smtpd_sasl_auth_enable = yes
#no anon access
smtpd_sasl_security_options = noanonymous
#where you auth requests are allowed to go to
smtpd_sasl_local_domain = $myhostname
#lets bad email clients like outlook express to work w/ smtp auth
broken_sasl_auth_clients = yes
#and your security restrictions
smtpd_recipient_restrictions =
permit_sasl_authenticated,
permit_mynetworks,
check_relay_domains

as for your smtp not working for dyndns... i dont know.. you probably are running this through a firewall.. so ensure that your ports are open on the firewall / or are properly forwarded.

and dont be too discouraged... smtp auth is a pain in the butt sometimes ;)

yea, I have sasl and ssl support set up locally.

snip of main.cf

Code:

smtpd_sasl_auth_enable = yes

smtpd_sasl_password_maps = hash:/etc/postfix/saslpass

smtpd_sasl2_auth_enable = yes

smtpd_sasl_security_options =

broken_sasl_auth_clients = yes

smtpd_sasl_local_domain =



smtpd_use_tls = yes

#smtpd_tls_auth_only = yes

smtpd_tls_key_file = /etc/postfix/newreq.pem

smtpd_tls_cert_file = /etc/postfix/newcert.pem

smtpd_tls_CAfile = /etc/postfix/cacert.pem

smtpd_tls_loglevel = 3

smtpd_tls_received_header = yes

smtpd_tls_session_cache_timeout = 3600s

tls_random_source = dev:/dev/urandom

smtpd_sasl_password_maps = hash:/etc/postfix/saslpass looks like so,

Code:

# $Header: /var/cvsroot/gentoo-x86/mail-mta/postfix/files/smtp.pass,v 1.2 2004/07/18 03:26:56 dragonheart Exp $

#

outbound.mailhop.org    myusername:mypassword

So I am not sure what the deal is. The u-name and passwd will not get passed for outgoing mail.

Another question,
I have two supported types of smtp auth set up plain and login how do I "force" those to be used because I can still connect to my smtp server with no auth what so ever.

smtpd is of course for the server side As some one from the gentoo forms pointed out to my foolish self. I would also need the lines with smtp for the client side of things:( so any ways It "almost work now my mail.log error:::

Code:

Aug 25 14:52:21 Myhost postfix/smtp[7478]: BDD1B59733: to=<myemail@isp.com>, relay=outbound.mailhop.org[63.208.196.171], delay=1, status=deferred (Authentication failed: cannot SASL authenticate to server outbound.mailhop.org[63.208.196.171]: no mechanism available)

They offer all types of auth, what the heck am I doing wrong.
