I'm not certain that this will help make '.smtp' entries behave as you
want, but the [EMAIL PROTECTED] on the left side of your entries are what
the SIMS docs refer to as 'local aliases', so they should be enclosed in
angle brackets:
<[EMAIL PROTECTED]> = [EMAIL PROTECTED]
Also (without specifically re-reading the docs on the '.smtp' router
syntax), I'm not sure that you need to include the user name on the right
side of the entry. Try:
<[EMAIL PROTECTED]> = domain.com.smtp

Again, [EMAIL PROTECTED] is a local alias and needs to be enclosed in
angle brackets as <[EMAIL PROTECTED]>.
