[Dovecot] sieve pigeonhole vacation filter responding when recipient is not explicitly listed

[Milan Cvetkovic]

Thanks, that helped, although I am still somewhat puzzled:

# /usr/lib/dovecot/dovecot-lda \
     -d user \
     -f john.doe at somewhere.com \
     -a aliastouser at mpathix.com \
     -r user at mpathix.com \
     -p /tmp/test.email

does not send vacation with my posted 'devecot -n' configuration

But from:
<http://wiki2.dovecot.org/Pigeonhole/Sieve/Extensions/Vacation#Configuration>

I was under the impression that I should also use

plugin {
...
   sieve_vacation_use_original_recipient = yes
}

However, vacation is not sent only when this option is set to 'no' (or 
defaulted to 'no')

Am I misunderstanding 'sieve_vacation_use_original_recipient' option:


"This specifies whether the original envelope recipient should be used 
in the check for implicit delivery. The vacation command checks headers 
of the incoming message, such as To: and Cc: for the address of the 
recipient, to verify that the message is explicitly addressed at the 
recipient. If the recipient address is not found, the vacation action 
will not trigger a response to prevent sending a reply when it is not 
appropriate. Normally only the final recipient address is used in this 
check. This setting allows including the original recipient specified in 
the SMTP session if available. This is useful to handle mail accounts 
with aliases. Use this option with caution: if you are using aliases 
that point to more than a single account, senders can get multiple 
vacation responses for a single message. Use the LDA -a option or the 
LMTP/LDA lda_original_recipient_header setting to make the original SMTP 
recipient available to Sieve. "

Thanks, Milan
