That is OK. You can also do dynamic signing based on the sender address
in the From: header. Here is what I use:
external_smtp:
driver = smtp
dkim_selector = whizbang-dkim
dkim_domain = DKIM_DOMAIN
dkim_private_key = DKIM_PRIVATE_KEY
dkim_strict = 0
dkim_canon = relaxed
Where the macros are defined as:
DKIM_DOMAIN = ${lc:${domain:$h_from:}}
DKIM_FILE = /etc/exim/dkim/${lc:${domain:$h_from:}}.priv
DKIM_PRIVATE_KEY = ${if exists{DKIM_FILE}{DKIM_FILE}{0}}
If no key file exists for the domain in the "From:" header, no signing
is done.
