dovecot - Nov 2019 - Accessing the -a and -d from dovecot-lda

I've got exim set up to deliver like this:


command = /usr/local/libexec/dovecot/dovecot-lda -a
$original_local_part@$original_domain -d $local_part@$domain  -f $sender_address


If an email to is bob+sales at ish.com.au then we should have "-a 
bob+sales at subdomain.ish.com.au -d bob at ish.com.au".


Now in dovecot, only bob at ish.com.au is a real user but I want to be able 
to use both addresses in different places. For LDAP lookup I need to 
reference bob at ish.com.au. But in sieve, I need to see the original 
address with plus notation.

However, dovecot appears to get the "-a" address into %u and the
"-d"
address can't be accessed.

Is what is the point of dovecot-lda having both -a and -d options? Can I 
get at both bits of data?


Thanks

Ari

In Sieve, the "envelope" test always uses the original envelope TO 
address (-a) for the "to" envelope part.
