Is there any facility to let dovecot do username mapping?
Yes, but can you change your passdb? You can use any passdb that allows
specifying [EMAIL PROTECTED] extra field
I can use a script to parse genericstable or even virtusertable and add this information at the end of the dovecot-passwd-file?
I guess. Just make sure that the file is updated using mv (rename()) command so that it gets updated atomically (so Dovecot never reads partially written files).
And I can still use /etc/passwd as a fallback in case something goes
You could set that up with:

passdb passwd-file {
  args = /etc/dovecot.passwd
}
passdb passwd {
}

Also if you keep using userdb passwd, you don't need to have the uid/gid/home in the passwd-file at all, so the files would then look like:

domain1_user:{plain}pass::::::[EMAIL PROTECTED]

Thanks a lot! This is exactly what I was looking for, but I didn't really think it was possible. Thanks for a great program!
