[Dovecot] Dovecot LMTP does not pass envelope recipient +detail to sieve

Indeed it did. Thanks!

I was surprised to find that sendmail does not pass +detail during LMTP, 
even though the default EnvToL rewrite rule declared in the local LMTP 
mailer definition preserves it.

This was my first dovecot setup, so I didn't realize at first that the 
lda_original_recipient_header in the LDA config file would also take 
effect for LMTP.  Once I figured that out, it was a simple matter to use 
your LOCAL CONFIG rule to have sendmail add the requisite header.

Given that LMTP does in fact parse X-Original-To (or any other header of 
your choice) when lda_original_recipient_header is defined, I think one 
would say that dovecot LMTP does already support this natively.

So it's not really a hack, it's just a matter of setting the dovecot 
config variable and ensuring that the MTA adds the corresponding header to 
each message.
