Hi, I am a little bit stuck with prepending one and exactly one additional header to outgoing mails that are sent from local users. In fact I want to add a VBR-Info:- header for outgoing mails.
Local users use a seperate MSA port (own IP-socket in master.cf). The socket is configured with smtpd_proxy_filter off and using content_filter. So the whole mails gets queued before giving it to amavis (in my setup). Inside the MSA part, I first defined a check_sender_access rule and thought that would do the job. But today I saw that for _each_ To: address a header is prepended. So if I write a mail with eight recipients, I see eight VBR-Info:-header lines in the result. So I thought I need a different method and configured header_checks: # header_checks if !/^VBR-Info:.*roessner-net(work-solutions)?/ /^From:....@roessner-net\.com/ PREPEND VBR-Info: md=roessner-net.com; mv=dwl.spamhaus.org; mc=all /^From:....@roessner-network-solutions\.com/ PREPEND VBR-Info: md=roessner-network-solutions.com; mv=dwl.spamhaus.org; mc=all endif # Any other checks for incoming and outgoing mail goes here But this does not change anything. Same result. And I fear I understand why. It is the cleanup that does the checks for each outgoing mail. Is that right? Do you have any idea, how I could solve this? Thanks in advance Christian
