#37 sign extra domains

[isaac]

I am trying to add a signature using lua but not working. domain is in SignTable and KeyTable.
for example if my domain was example.com, I am making the follwing call, but example.com is not added.
odkim.signfor(ctx,"test@example.com")

Thanks in advance.

I have some experience signing for multiple domains using a key and signing table.Im not super clear on your example though, are you simply wanting to be able to sign for @example.com and also sign for @example2.com?  Do you want to use the same key for both or different keys?

Mike,

Thanks for getting back to me.

I am trying to create a second signature that would be unique for anyone sending from within my platform. By doing this I can build custom repuation on each sender using a domain I own.

SignTable has entry: @.example.com example_key
KeyTable has entry: example_key %:selector:private.flie

Emails could get 2 signatures.
1) the from address domain
2) xyz.example.com where xyz is custom identifier per sender.

In Lua I am able to get xyz.example.com throught odkim.get_header(ctx,"HEADER",0), but when I pass it to odkim.signfor(ctx,Header) nothing happens.

I do not want to have 2 opendkim processes running in order to add second signature.

Thanks Again,

Isaac

A followup.

I took a look at the code inside the "dkimf_xs_signfor" method. I found that lua_pop(l,top) is causing ctx to be null. I commented it out and recompiled. The "signfor" method then did work, but it added a signature for the wrong domain.

The only way I see I will be able to do what I am an looking to do is to add a second opendkim process running with a different config.

Thanks,

Isaac
