One of these days I'm going to propose the Thunderbird + K-9 mail addons that say 'set the sent from email address to be equal to the sent to email address', that way if [email protected] is the recipient, it will be the sender to any replies, rather than the MUA default replying with [email protected] (but that's a separate discussion)
It's not a literal alias, but it works out fine.
