Comment:

 +1 with caveats.

 Exploding by commas would cause issues with {{{"Doe, John"
 <johndoe at example.com>}}} becoming {{{"Doe}}} and {{{John"
 <johndoe at example.com>}}}.

 Patch attached to handle an array only. I would think it should also
 explode by commas outside of quotation marks, but this is a start.

 I'm looking at how the function handles CC and BCC headers and I see they
 currently explode by commas without regard for quotation marks. That may
 be enough to classify this as a bug. The function also doesn't appear to
 support {{{CC: johndoe at example.com\nCC:janedoe at example.com}}} as headers,
 which does work for PHP's {{{mail}}}.

 I'll try to generate some test cases and build a patch to fix this.
