Postfix & spamassassin - how to whitelist smtp auth connections
Posted on 2004-08-13
I am running postfix, amavis, apamassassin, and razor and it is working well.
However I do have a minor problem in that sometimes email from people outside the office is classed as spam because they are using dynamic IP addresses etc... They all use SMTP AUTH (no TLS) to our mail server.
I have had a look but postfix does not appear to add any custom headers when people send mail via SMTP AUTH.
Is there any way to configure postfix to add a custom header so that I can then look for it and whitelist these emails in spamassassin?
