Add a custom email alias to all my mail enabled users

Question

Hey Everyone,
I'm trying to add an email alias to all my mail enabled users using powershell.
 I'm in a dir sync setup can I do something like the below.Of course the smtp:$($a.lname)_$($[email protected] isn't working for me. It was posted online as "$a.alias", which isn't what I need. I need
to add [email protected] to every mailbox.A crappy voice mail system software that can't alter it's send To address format template is driving this change.  I don't want to use an address policy, due to it
changing the default reply in the process.
if someone can help me get this script working that would be fantastic.
$users = Get-Mailuser
foreach ($a in $users) {$a.emailaddresses.Add("smtp:$($a.lname)_$($[email protected]")}
$users | %{Set-Mailuser $_.Identity -EmailAddresses $_.EmailAddresses}

I don't have an Exchange environment to test this. I just fxed up the syntax. Does this work:
$users = Get-Mailuser
foreach ($user in $users) {
$user.emailaddresses.Add("smtp:$($user.lname)_$($user.fname)@domain.ca")
$users | % { Set-Mailuser $_.Identity -EmailAddresses $_.EmailAddresses }
