Yes, but note that relocated_maps will reject the message with
"relocated to userexample.com" as the rejection reason text.
Some mail systems mangle reject messages such that the
sender will never see rejection text.
Vacation or similar auto-responder will generate a new message
which may be more likely to be received at the expenses of
somewhat more processing required by your mail server.
Using vacation also allows you to actually receive the message
sent to your old address. This may be desirable during a
domain name transition.
Either vacation or relocated_maps may be appropriate depending
on your needs.
