Hi,

Mac Mail won't let me send e-mail with attachments > 31.5 Mb, and tells me that it was rejected by the mail server as the "server limit is 31.5 Mb".

I know this is utter rubbish as I'm the mail server admin, and there is no limit! How can I remove this limit from Mac Mail? I use Thunderbird on Windows and happily send 1 Gb file attachments.

Maybe you should sniff smtp packets by wireshark to see what is sent to mail server and what is a real reply from the server. Then maybe overcome will be easier...
 
Check the rejection notice and see which mail server rejected your large attachment. It was probably the recipients mail server if you have no limits on yours. A good rule of thumb on sending large attachments is to keep the entire message plus attachments below 5 mb. Some mail servers just won't accept larger emails. There are a lot that do but not all.
 
Huh?

Do you routinely send attachments that big?

Other admins must HATE that.
