Mail reply-to, redirects and forwarding ...

[Kevin Callahan]

My BIL's wife has an iPhone and runs a small business.  She has about  
8 email addresses relating to a couple of domains.

They recently bought a new MBPro and .Mac hoping a redirect of those  
emails to their .Mac account (while employing the junk filtering)  
would help reduce the amount of spam that shows up, not only on their  
Mac, but on the iPhone.

I told them to  keep Mail running on their MBPro.

They question they have is about replying with an address that had its  
mail redirected/forwarded to their .Mac address.

If they redirect/forward email sent to Address A to their .Mac  
account, can they REPLY with Address A ?  Thus far, they say if an  
email shows up in their .Mac, they don't have an option to set a rule  
whereby email forwarded from a certain address will use that address  
when they hit REPLY.

is there a way to do that?

They can set up email accounts for each of those domain email  
addresses, but I think the junk filtering at the server level, as  
opposed to at the Mail client level, is what they're looking for.

In fact, is mail that is forward to a .Mac account filtered for junk  
at the server level first?

Thanks in advance,
Kevin
