Hello,We have a mail service that uses postfix and dovecot. We would like to
send an email to a large number of users(about 100K). However, it takes too
long to send the email through smtp. Is there any solution to deliver the email
locally to all user mailboxes directly.dovecot uses lmtp for transfering local
emails. the worst solutoin is that copy the email to all mailboxes via linux
file system. But we would prefer to use some tools provided by dovecot like
doveadm. is there any way to do this job?
