Maximum mail size (individual piece of mail)

Help! (Home for newbies)

Is there a “maximum size” for an individual piece of mail" setting somewhere? I don’t want to muck around with config files if there’s a nice web template somewhere.

Thanks.

There’s no universal standard for email size limits, but many providers around the world use limits around 20-25 MB.

In Postfix the default is 10 MB, and you can change it for internal use, but for internet-facing MTAs it’s best to stay in roughly the 10–25 MB range for compatibility.
