[AusNOG] Straw poll: what is your email message size limit?

[Scott Howard]

Having worked for multiple email vendors over the past few years, I've seen
settings from dozens/hundreds of companies large and small.

If I had to pick a single size that's used, it would probably be 20MB - but
there's no end of variation.  10MB is common, although mainly for historic
reasons, and the number of people with such a low limit is dropping.  25MB
and even 50MB aren't uncommon.  100MB is rare, but out there - mainly in
situations where mail is being sent to a specific recipient and they have
also up'ed their limited.  I've even seen one company who wanted their
limit set to 1GB...

Certainly increasing to 20 or 25MB will likely cause few delivery issues,
and in the days of ESMTP, most servers will reject the message during the
conversation phase if it's too big which used to be one of the issues
previously.

  Scott.
