    Why There Is A Limit On The Size Of The Email

    How to Send Large Files Effectively

    These are some of the main reasons for the mail size limit:

    • Mail systems often arbitrarily limit the size their users are allowed to submit.
    • You also cant email large files because the message will often pass through several mail transfer agents to reach the recipient. Each of these has to store the message before forwarding it and may therefore also impose size limits.
    • The recipient mail system may reject incoming emails with attachments of a certain size.
    • For security reasons, all email service providers limit the maximum email size that an email account can receive. Else, with no maximum email size limit, the email server would risk being besieged with very large emails, causing it to desist working properly.

    The result is that while large attachments may succeed internally within a company or organization, they may not when sent across the internet. Email infrastructure is not designed to cope with large files. Thats why most email providers impose limits on the maximum size of a single attachment.
