[xmail] Re: Mailbox size
The problem here is that not all SMTP servers tell the receiving server how big the email will be before sending. 1. If the xmail switch you mentioned could enable xmail to drop the connection once the quote was reached, then the sending MTA would just try again because it was dropped mid stream. I don't know if you can bounce an email once you have processed the DATA command. 2. If the xmail switch you mentioned could enable xmail to drop the message after completely receiving it, then that would be ok, but I suppose you could run a filter to check the quota size *after* the msg is received, and that would be the same. The filter could even bounce a message back. I know which one Davide will take.

You can use mailbox size together with MaxMessageSize server.tab=20 property.
