strict RFC smtp server syntax

Disallowing illegal syntax in MAIL FROM or RCPT TO commands. This may cause problems with home-grown applications that send mail, and with ancient PC mail clients. For this reason, the requirement is disabled by default ("strict_rfc821_envelopes = no").

• Disallowing RFC 822 address syntax (example: "MAIL FROM: the dude <dude@example.com>").
• Disallowing addresses that are not enclosed with <> (example: "MAIL FROM: dude@example.com").

use this syntax:

MAIL FROM:<marysue@hughes.net>
250 2.1.0 Ok
RCPT TO:<marysue@hughes.net>
554 5.7.1 <marysue@hughes.net>
