and it's my config

Code:

# SASL paramters
smtpd_sasl_auth_enable       = yes

smtpd_sasl_local_domain      =
broken_sasl_auth_clients     = yes

                               permit_sasl_authenticated,
                               reject_invalid_helo_hostname,
                               reject_non_fqdn_helo_hostname

smtpd_sender_restrictions    = reject_non_fqdn_sender,
                               #reject_unknown_sender_domain,
                               permit_mynetworks,
                               permit_sasl_authenticated

smtpd_recipient_restrictions = reject_non_fqdn_recipient,
                               reject_unknown_recipient_domain,
                               permit_mynetworks,
                               permit_sasl_authenticated,

                              # check_policy_service inet:127.0.0.1:60000,
                               permit

smtpd_data_restrictions      = reject_multi_recipient_bounce,
                               reject_unauth_pipelining

which one of this must be disable to postfix doesn't reject mail wants send from mail client from PC

You must tell your client (kmail/whatever) to AUTHENTICATE against the smtp server, using the same credentials as you use for pop3/imap. There should be an option saying something like "Server requires authentication" on the SMTP settings....

i can success to send mail
but why mail go to spam ( in gmail )
gmail is not very sensitive for this. but yahoo usually go to bulk
how can i solve this for both service (yahoo and google)

[kilburn]

There's no "bulletproof" methodology to ensure your mails are not marked as spam in gmail/yahoo/whatever. Obviously, if such thing was possible, every spammer out there would use this method and everyone would end up covered by spam.

That said, make sure that:
1) Your domain's spf records are set and correct
2) Your mailserver uses an appropiate helo
3) Your server is not listed in any blacklist

I'll send you my mail through pm, so you can send me a message and I'll see if there's something misconfigured...
