Re: [mailop] Maximum message size - tag along question.

[Brandon Long via mailop]

We choose our limits based on the base64 size and message that to the user,
ie we say we handle
25MB attachments and set the message size limit at 4/3*25 + some overhead.

For most users, trying to explain the differences is not useful.

My usual limit is 100MB and then I explain to my users that:

1) That's the _email size limit_ and not the size limit for an attachment to an 
email
2) Email is inefficient when used for transferring files, thus overhead
3) Email is not intended to be a system for routinely moving large files
4) You can't garuntee what other mail servers in the chain may have enabled as 
maximum size limits, so upping the local limit isn't going to solve all your 
problems
5) Look at OneDrive, Dropbox or Google Drive as readily available ad-hoc file 
transfer options.

At 100MB I hear very few complaints. I certainly wouldn't be making the limit 
any higher for the OP's scenario.

Some legacy mail systems I have to deal with, struggle with the combination of 
large email + large number of recipients (when processing rules require you to 
bifurcate the email into one-email-per-recipient in order to enable 
per-recipient rule handling, your single 100MB email can become several 
gigabytes of processing) so that's another potential factor.

Do you take into account the 4/3 inflation with Base64 encoding and / or allow 
for any message body when setting the maximum message size that your servers 
allow?
