I noticed that many places in the documentation and in examples

sieve.
The documentation also mentions that lmtp is preferred over lda, and
seems to say in places that sieve will operate without issue in either
case.
Does it matter to sieve implementation if one uses only lmtp?
LDA is older, think of LMTP as a more modern replacement. LDA has to
launch a separate process and process one message at a time. LMTP
maintains a running service and can stream multiple messages in a single
connection, therefore LMTP is a lot more efficient.
You will see a lot of bad advice on the internet, or old outdated
advice. Tutorials that use LDA is an example of old, outdated advice.
Sieve itself doesn't care which one you use, but there are other reasons
to prefer LMTP.
Just wish LMTP would not end up with duplicate Return-Path headers..
