If **can** be in EHLO response, in bytes::

    swaks --to aaa at domain --quit ehlo
    ...
    <-  250-SIZE 157286400

Then you have to lower that value by number depending on used encoding, 
eg. in case of Base64 max. message size can be 30-40 % lower. Thus
generally, safe value is half of reported, in this case ~75 MB.

But, any MTA on the path can have its own limit, and some don't provide
SIZE extension (or provide it without value), but apply limits...

regards
