How secure is cfmail with username and password

To log into a remote mail server I need the username and password. Cfmail won't work correctly without it.

I'm sending 10 - 40 emails using cfmail daily. I am not using SSL and will not use it.

How secure is mail being sent this way? I don't want to compromise my email username and password by having someone sniff it out.

The best described answer gets the points.

its perfectly safe unless someone hacks your coldfusion server (highly unlikely) becuase those varaibles would never appear on any page you send. there being taken from the page your sending the email off of and are hidden to any view source procedures :)
if you are using tls & your code suggests you are, then you are fine (fine in the nothing is ever 100% kind of way)

In terms of cfmail, it operates pretty much as any email client. Many clients and many server setups don't support ssl or tls so cf is no better or worse.

plusone - couple of things, firstly it's not exactly highly -unlikely- that someone hacks a cf server - happens all the time. Just last year, there was a huge number of servers hit with a hack based on a vulnerablilty in the fckeditor that was bundled with CF. This was a total compromise attack.

But I don't think that's really the issue, if you are using an external mail server and Qsorb seems to indicate that with "" then authentication will be sent in plain text unless the mail server supports ssl or tls, tls being the better option -and- you set cfmail to use it.

I included tls but have no idea if email server supports it, or if I need get a digital certificate from somewhere to use it. But as you said, sounds good, if in fact stating to use it then automatically initializes it.
if you include the attribute useTLS and the server doesn't support it then the communication session will fail. Basically CF says I want to see a secure handshake - if the server says no way then cf says oh well - bye. You should not need a cert as that is a mail server side thing.

here's a quick read with a bit more info - it references secure email with gmail but the it's useful in any case

and this might be useful

looks like comcastbiz does do tls on 587
