    I've noticed lately that incoming mail addressed to users that host their domain on our server are having their mail end up in the queue instead of having it immediately hit their account.

    If I manually send, the mail is immediately sent, but am wondering why this lag in queue is occurring.

    As I check the queue, I can see new messages come in addressed to the same domains as those in queue at the bottom of the queue and then when I refresh, the new emails are gone as they've been delivered immediately, but some hit the queue and stay for 15 minutes or more.

    Any ideas as to why some email addressed to our server isn't immediately being sent and is ending up in queue? Any feedback appreciated.

    Look at the message ID of the stuck messages, then look in your mail server log. For example, if the message ID is 1NbajE-000054-PG, then do this:

    grep 1NbajE-000054-PG /var/log/exim_mainlog

    This will show you how it arrived, and probably why it couldn't immediately deliver the message. Could be the end user's mailbox was full or who knows. Exim tries to deliver those stuck messages every so often, but the longer it can't be delivered, the longer it waits in between delivery attempts.
