mailscanner and opendkim

[Jason Ede]

I followed this with a bit of tweaking... http://www.postfix.org/MULTI_INSTANCE_README.html

I'm working on a document internally that might try and post on the MS wiki when done, but won't be that soon.

>From the above link the main this is to make the inbound instance the MS one and then just pass straight through to the outbound instance (not via a milter as the above instructions use) and then sign on the outbound instance.

I've also found it helps with debugging if give each postfix instance a different hostname in the config so you can distinguish in logfile what is going on.

Jason,


Do you have any links for any tutorial on how to do this?
I'm not yet familiar on this that much.

Thanks,

John

We use DKIM on our outbound here with MS and postfix.  We just have 2 instances of postfix running. The first one scans the email with MS and the second signs the email before it leaves our servers.

Hello All,

I've just implemented MailScanner.  Great software by the way!  When I run MailScanner I run into OpenDKIM problem.  My OpenDKIM was working already before I run the MailScanner.
Now even if OpenDKIM adds a signature, it will result o dkim: permerror (bad sig).  I know MailScanner inserts some information inside the header and probably overwrites the OpenDKIM header information?
If so, does anyone can help me solve this?


Looking forward to hearing anyone.

thanks,

John
