Malformed DKIM Body signature, Postfix












0















I am having some trouble with my email server. (postfix/dovecot on ubuntu LTS) I am getting an invalidated DKIM body signature. This is what I get from the header.



DKIM-Signature: v=1; a=rsa-sha256; c=relaxed/simple; d= harboragedata.com; h=message-id:subject:subject:to:from:from :date:date:content-transfer-encoding:content-type:content-type :mime-version; s=dkim; t=1549292192; x=1551884193; bh=MHynPeRWE5 ijdyfHAg56mlHu5YU0zI2E9Qvnom0Vqic=; b=R0h7Jcs+8vhbr2001XDJuhZY5B zfFDWhYcb3AV4Lwn9fk5Lb2FER6qpnxypgKaNQq9jJuOvNUzhLPVC2sK/jHa747F EoqfbIGXAlqHABoSPGWK4X5TnOlK3A/B3Ld1k9YmU3t8r7W3C/td9DNOHaKddr6b 2tbHRpXhljvfNZ/yg=


I believe the "subject:Subject:to:from:from ....." is whats causing my issue.



I believe this has resulted from setting ignore flags in the header check file. (edit: i just removed all the flags and the signature is still malformed)



This is my header check file



/^Received:/ IGNORE
/^X-PHP-Originating-Script:/ IGNORE
/^X-Mailer:/ IGNORE
/^User-Agent:/ IGNORE



I set these flags because the header contained 'localhost' as the originating server. So I am not sure what I need to do here. I feel like fixing the "localhost" issue is the correct way to fix it, but I have been unable to determine what changes I need to make in the configs. I have tried a few things, and all have been unsuccessful.



Could use some direction on this! Thanks for your time.
