vacation script issue

Tue Dec 4 17:16:03 EET 2018

After some additional research and testing, it seems that my vacation
auto-reply is working when the sender doesn't have the same username (%n)
as a local account on the recipient imap server.

If test at xyz.com sends an email to  test2 at example.com, the vacation
auto-reply is triggered but delivered to the wrong mailbox.

Suppose I have an account test at example.com on my imap server, this account
has the same %n (test) as the sender address.

In this case the vacation auto-reply is delivered locally to the
test at example.com account instead of test at example.xyz

If I delete the test at example.com account from my imap server then the
vacation auto-reply is send through my relayhost and delivered to original
sender as expected.

Now I need to figure out how to solve this problem.
