RFC 5321, section 4.5.3.2 lists the various timesouts that an SMTP 
client SHOULD employ (noting that they MUST be per-command, not on the 
whole transaction). They include:
 * Time to Initial 220 message: 5 minutes
 * Response to MAIL or RCPT command: 5 minutes
 * Waiting for "354 Start Input" after issueing "DATA": 3 minutes
 * Waiting for next command from server: 5 minutes

So, any client that disconnects after waiting only 10 seconds is, while 
not explicitly spammy, at least poorly behaved.
