Why haven’t email attachment file size limits increased over the years?
In: Technology
Email is not a file transfer protocol.
Email by design allows for unsolicited messages to be delivered, so if you allow attachments of any size a hacker could very quickly overload your server and fill up it’s hard drives by sending emails with multiple recipients and large attachments.
For example if I can email a 5gb ISO, It would only take a couple of emails for me to crash your server.
Email attachment size limits have increased over the years but it’s rare to see larger than 20mb for the above stated reasons.
