For a long time I have had configuration where mails were fetched by fetchmail then passed to exim and then passed to dovecot via lmtp. Recently I remove dovecot module and mails are passed from exim to dovecot via dovecot-lda Yesterday I have some kind of accident and lost my .fetchids file so a lot of mails were fetched again. During duplicate hunting I found something strange: messages fetched yesterday (passed to dovecot with lda have additional line) have additional line at the end: for example

I'm somewhat confused with this. Is this normal?
