No, I wouldn't write the dovecot- prefix to log files. So while the
binary names would be dovecot-lda, dovecot-imap-login, etc. the logs
would contain only lda(user), imap-login(user), etc.

Another thing I was thinking about previously was that in process lists
they were prefixed with dovecot/. So the binary names could be lda,
imap-login, etc. but they'd show up in process lists as dovecot/lda,
dovecot/imap-login, etc.

But deliver also reads dovecot.conf and inside protocol lda {} it can
also override all settings from dovecot.conf. So I don't really like the
idea of splitting the configuration. Also in v1.3+ the only thing that
reads dovecot.conf is doveconf binary, master and deliver and everything
else get their configuration from it.
