> Following remarks made by @adarshasp87  on gitter,
> it turns out MailEnvelopeImpl uses an inmemory data structure to store temporary messages before enqueuing them.
> When the size extension is not enabled, this can cause "out of memory exceptions".
> We would rather like to rely on a DeferedInputStream, or the like, in order to allow very large messages reception in SMTP.
> Community members should feel free to contribute this simple fix.
