without doveconf -n and, in this case, postfix configuration, nobody can 
really help you. But:

Postfix seems to deliver the message to recipient user at domain2.com via 
LMTP. Dovecot verifies user at domain2.com as valid. How should Dovecot know 
that user at domain2.com is user at domain1.com ?

So, either:
a) reconfigure postfix to rewrite user at domain2.com into user at domain1.com 
before the message is passed to LTMP, or

b) have you Dovecot userdb rewrite the user. Return the file "user" with 
the correct domain.
