    It would be great to have email queue system that makes sure that no more than a specific number of emails per hour can be sent from the forum.

    In vbulletin this was a modification, so perhaps someone is capable of writing such mod for XenForo?
    It was called: Cron Based Mail Queue

    This is very important for smaller forums that run on shared hosting accounts.

    This is very important for bigger boards running on tight server allowances. +1

    Email throttling should be considered for sending emails and also domain throttling would also be good.

    I dont think that their is a need for me to further explain, if their is please let me know.

    ___EDIT___

    Email throttling

    Email throttling is a must if you have limits set by your host or email provider
    Email throttling is also a must to comply with email providers receiving limits such as hotmail, google etc, You can get a better understanding from email providers and their best practices from their postmaster pages. That being said don't expect to get a quick answer to the maximum number of emails you can send without being considered spam.

    Domain throttling
    This ensures that you do not send more emails than the set amount to a single domain such as hotmail, Gmail etc (*no spam folder for you)
    *other condition apply, i suggest signing up to feedback loops

    Email separation
    Email functions like mailings, registration and alerts should have the option for separate email addresses, Separating email addresses by their function is a best practice and over all ensures better inbox placement. The basic thought behind separating email addresses by their functions is a simple one that I can only explain by saying "don't place all your eggs in one basket"

    I'm on shared hosting with a 400 per hour limit so I would like this as well.

    If you go over ... could you be flagged as a spammer ?
    For business sites .... this Mailchimp addon could help ?

    They shut off my email until I contacted them so I would say yes.

    Is that a Suggestion or a Support issue ?

    Not only should this be included for peoples email sending limits I would like to ad that it is greatly needed for receiving limits, Basically every email provider such as hotmail etc has a limit of emails that you can sent to their domain based on their best practices and to respect their server resources, If a sender sends more than the considered safe amount per time frame you are considered a spammer and your inbox placement suffers.

    I placed it as a suggestion although i feel that it is a bug (I felt it would come across as arrogance on my part if I posted it as a bug)

    The other suggestion I have made recently was for XF to include an email "receive newsletter checkbox" so that I can collect email addresses and comply with spam policys.

    Another thing that I would like to put as a suggestion is for the ability to have a separate email address for mailings, registration and general notifications, Once again this falls under email best practices and gives over all better inbox placement.

    Seems logical.
    Might help with the throttling issue as well.
    You wouldn't want registrations throttled. But Mailing should for sure be throttled.
    Notifications, depending on how they are used, probably don't need throttling, unless you have a super popular thread, where everyone is watching ... and has email notifications selected.

    I do like your train of thought, the only issue's that I can see with not throttling either a single or multiple functions would be the ability to go over a set quota, Lets say for an example that a user has a quota of 100 emails per hour and sets a throttling limit of 90 emails per hour. that users can then keep track of how many non XF emails they send, however if they have ten registrations then their quota is met. I personal thinking is that their would be to many unpredictable variables to ensure that a set quota is met.

    Also if a user is sending mailings and has set a quota for domain names such as hotmail, any un throttled functions could possibly exceed the desired quota and lead to making a spam trap such as hotmail angry.

    any support for the idea?

    You have my support for email throttling, If I may also suggest a few things that are related to email throttling.

    Domain shuffling for outgoing emails (Better inbox placement/avoiding spam traps)
    Domain per hour throttling (Better inbox placement/avoiding spam traps)
    Newsletter Opt in process to comply to standards (include a check box)
    Separating email addresses for different functions, Registration - Board Emails - Mailings... (Basically standard email practice)

    I dont have exim on my server, since I switched to plesk based control panels. Using mailman at the moment. Would you be able to do a step by step?

    Would be very interesting to be able to schedule emails to users, to send 100 emails/ hour. Some of us have problems by the limit have servers and this is a problem.

    I suggest that for the next version this can be done, other systems already bring by default and do not have problems of limitations.


    I have this error by not administrate emails/hour
