vacation script issue

[fins]

Hello,


I have a complete Postfix + Dovecot + openLDAP setup almost working, the
only issue I have is the vacation script auto-reply that doesn't work
properly.

If I send an email to a user with the vacation filter enabled, the
auto-reply is send to a local recipient with the same account name.

So for example if I send a mail from test at xyz.com to test at example.com, the
auto-reply is received on the test at example.com address instead of the
test at xyz.com who's the original sender.

Here's a log file:


Dec  3 13:52:48 imap dovecot: lda(test at example.com): Debug: sieve:
executing script from /var/mail/example.com/test/.dovecot.svbin
Dec  3 13:52:48 imap dovecot: lda(test at example.com): sieve: msgid=<

response to auto-submitted message from <MAILER-DAEMON>
Dec  3 13:52:48 imap dovecot: lda(test at example.com): sieve: msgid=<

mailbox 'INBOX'
Dec  3 13:52:48 imap postfix/pipe[6663]: D835A300E05: to=<test at example.com>,
orig_to=<test at xyz.com>, relay=dovecot, delay=0.1, delays=0.03/0.01/0/0.06,
dsn=2.0.0, status=sent (delivered via dovecot service)


Can somebody help with this issue and/or point where to go for debugging?


Please find my dovecot configuration bellow:
