cfmail using Gmail SMTP

I wanted to have a cfmail tag use my Gmail SMTP to send mail, which was relatively straightforward, but there is some vague language in the Google help doc that didn't immediately translate to cfmail attribute settings. I did find plenty of search results on the topic, but most threads were a little confusing and noted differing experiences between developers. So I've taken a little time to experiment and thought I'd share the results.

From both my gmail.com account and my Google Apps for Your Domain mail (gmail for custom domain name) accounts I was able to find the same help doc for standard POP/SMTP configuration.

We can quickly deduce that the username attribute should be your full e-mail address (including @gmail.com or @your_domain.com), and the password is of course your Gmail password.

The help doc provides the following information for the outgoing/SMTP server configuration:

smtp.gmail.com (use authentication)
Use Authentication: Yes
Use STARTTLS: Yes (some clients call this SSL)
Port: 465 or 587

So, how does the above information translate to relevant cfmail tag attributes (server, port, username, password, useSSL, useTLS)? It's a bit more specific than the Gmail help doc suggests...

ColdFusion round() function bug when operation performed on argument

UPDATE (July 15, 2009): This "bug" still exists in Adobe ColdFusion 9 beta 1. It also seems to behave the same in OpenBD 1.1. This bug does not seem to exist in Railo (I can't reproduce any similar problems in Railo 3.0 or Railo 3.1). For example, round(4.0005*1000) outputs 4000 from both AdobeCF and OpenBD while Railo outputs the expected 4001. There may very well be other scenarios where a floating point representation causes similar unexpected results in Railo as well, but I have not been able to find it yet (nor have I performed an absolutely thorough test, maybe soon if time permits).

Have you ever used a CFML trick like this to round a number to the nearest hundredth?

<cfoutput>#round(someNumber*100)/100#</cfoutput>

I have, and I never had a problem, until...

<cfscript>
    valueA = 4000.5;
    valueB = 4.0005*1000;
    roundedA = round(valueA);
    roundedB = round(valueB);
</cfscript>

You'd be perfectly sane to expect the first two variables to output as 4000.5 and the second two (rounded) to output 4001. Unfortunately, roundedB is output as 4000, not 4001!

This definitely appears to be a bug, but I do have a rather simple workaround...
