Not if my mailserver is extremely secure and uses SPF records and domain keys which state only mail coming from XXX server us legit, so people don't fake my e-mail addresses (as well as my clients). I used a paid SSL cert to encrypted login to mail server and SMTP for sending. 587 works fine for now, and is a SMTP spec port.
