While looking into why my outbound bandwidth was spiking every 15

The server that it was sending to supports EHLO, in fact it is also my
own server. Here's what the session states after an EHLO command:
EHLO mail.mailpure.com
250-heimdall Hello [66.109.52.12]
250-SIZE 20971520
250-AUTH LOGIN CRAM-MD5
250 OK
My understanding of ESMTP is that if the message is more than 20,971,520
bytes as indicated in the SIZE response, then it should not be sent.
This message was more than 41,874,785 bytes and it was sent regardless.
RFC 1870 "SMTP Size Declaration" does not require the sending machine to
pay any attention to the SIZE declaration.
The receiving server does have a problem in that a return code should be
sent, temporary or permanent (4xx or 5xx).
Where does it state that this RFC does not require the sending (client)
machine to pay attention to this parameter?
Does Imail claim to be compliant to RFC 1870 and support this extension?
