My mail server does not support plus addressing but it does support minus addressing.

Eg. 

- This does not work.

But, 

abuse-6f5d8566-87e8-4a26-87b0-6e545fcf7f3d@darwin.int

This works - i.e mail is delivered to the abuse@darwin.int account.

Is there any configuration in dcs to tell it to use the '-' character instead of '+' ?

Thanks in advance,

Amol
