Hi,

I am using Dovecot LDA as LMTP renders envelope extension unusable.
(...)
from my master.cf:
dovecot unix - n n - - pipe
   flags=DRhu user=vmail:vmail argv=/usr/lib/dovecot/dovecot-lda -f
${sender} -a ${original_recipient} -d ${user}@${nexthop}

Sorry for causing problems and wasting time. The problem was with
lacking -r parameter in LDA invocation:

"-r <address>: Final envelope recipient address. Defaults to -a address,
but may differ if e.g. aliases are used or when dropping the +ext part.
(v2.0.3+)"
So the final recipient that is used by vacation was always set to the
original recipient value.

With the following Postfix config everything works exactly as expected.
Response is generated if mail is send to +exct address and is not
generated if it is send to an alias unless the alias is configured in
"addresses variable.

Also the sieve_vacation_use_original_recipient parameter works as
expected.

dovecot unix - n n - - pipe
   flags=OXDRhu user=vmail:vmail argv=/usr/lib/dovecot/dovecot-lda -f
${sender} -a ${original_recipient} -r ${recipient} -d ${user}@${nexthop}


Thanks,
Karol
