How do I separate multiple email addresses in cfmail

Question

Do I use a comma or semicolon? I can't seem to find it in the live docs. I also can't seem to find any consistency looking online as some examples use a comma while others use a semicolon. Are both acceptable?

Solution 1

Per https://helpx.adobe.com/coldfusion/cfml-reference/coldfusion-tags/tags-m-o/cfmail.html

Message recipient e-mail addresses:

• Static address, for example, "[email protected]".
• Variable that contains an address, for example, "#Form.Email#".
• Name of a query column that contains an address, for example, "#EMail#". An e-mail message is sent for each returned row.

To specify multiple addresses, separate the addresses with commas.

(emphasis mine)

I do believe semicolons will work as well.

Solution 2

You can use either of them, and it should be fine. Although for consistency with existing email clients, I'd use a semicolon.

I'm not sure how commas would behave in other CF engines, such as Railo or OpenBD, whereas ; would work on all of them.
