Question 1 - Is there any difference in the following?
A mailbox with a filter that redirects all mail to an external account.
mailbox - email@example.com
smtp recip filter set to redirect to "firstname.lastname@example.org"
target recip - email@example.com
A forwarding alias
alias - firstname.lastname@example.org
forwarding to "email@example.com"
Is the internal action the exact same and is this message received by the 3rd party (in the case, an exchange host) just the same?
If an alias is setup, everything is identical as in Scenario B, except the forwarding is set to two e-mail addresses, one internal and one external, does this make any difference in how the e-mail is received by the external host.
forwarding to firstname.lastname@example.org
The reason I ask - Ideally, though I will be using an exchange account, I would still like the incoming e-mail to forward to my pop account here as well as go to the external exchange server - An alias forwarding to two account would be the way to go - I just want to make sure e-mail between scenario A and scenario B aren't handled differently by FQ or received differently by external exchange host. FYI - I don't want to tinker with MX records.
