Based on extensive experience with busy mail-relay hosts, the minimum per-command timeout values SHOULD be as follows:

Initial 220 Message: 5 minutes
A Sender-SMTP process needs to distinguish between a failed TCP connection and a delay in receiving the initial 220 greeting message. Many receiver-SMTPs will accept a TCP connection but delay delivery of the 220 message until their system load will permit more mail to be processed.
MAIL Command: 5 minutes
RCPT Command: 5 minutes
A longer timeout would be required if processing of mailing lists and aliases were not deferred until after the message was accepted.
DATA Initiation: 2 minutes
This is while awaiting the "354 Start Input" reply to a DATA command.
Data Block: 3 minutes
This is while awaiting the completion of each TCP SEND call transmitting a chunk of data.
DATA Termination: 10 minutes.
This is while awaiting the "250 OK" reply. When the receiver gets the final period terminating the message data, it typically performs processing to deliver the message to a user mailbox. A spurious timeout at this point would be very wasteful, since the message has been successfully sent.

You can't change most of those settings.
Tarpit will deal with recipient, and the SMTP settings will deal with the time out.
