my issue is when a user connect with smtp auth on port 587 and send a mail to a local user ( someone from the same domain) then it get filtered and never trigger the defined($SendmailMacros{"auth_authen"})) part. Is there any solution to that ? It seems that smtp auth is simply ignored for local delivery even if the log show a successful smtp-auth for this connection.

I don't believe this.
To verify add a md_syslog('warning', $RelayAddr . "/" . 
$SendmailMacros{"auth_authen"}) before the if() statement.

Or do you happen to have separate configurations for port 25 and 587?

the filter_sender works for external recipient and skip all filtering but impossible to do it for this case. I want to skip filtering because spamassassin trigger a LOT of false positive rules when in this configuration (all RCPT and HELO rules).
