It could be the user needs to use the manage identities feature in 
Thunderbird.  If you have an email address A that also has an alias 
address B, when you set up the email address A account in Thunderbird, 
it will use the A email address when you reply to messages even if the 
message was sent to the B email address.  Using the Manage Identities 
feature (on the Account Settings page near the bottom), you can add the 
alias email address B.  Once done, when you reply to a message sent to 
the A address, Thunderbird will use the A address for the From: field.  
When you reply to a message sent to the B address, Thunderbird will use 
the B address for the From: field.  If you have multiple address that 
all consolidate to one address, this is a convenient way to receive mail 
and reply using the correct address for the reply.

Just a thought,
