Thank you for that and all the other responses too I suppose I'm guilty - I was just doing it because you do and always have. I hadn't really thought of it this way Adam and now I suspect I'll ask the question each time - do I need to validate this address.

RE: Apostrophes in email addresses
No problem at all - I read your article end to end and it made me think about (in some ways challenge) something I'm doing and that's a good thing - as I said I have always validated emails addresses because I always have, and when I thought about it, it was but for no other reason than I always have. Then I thought do I really need to do this - I'll take a more app by app approach in future. ++ Kevin Parker ++ -Original Message- From: Adam Cameron [mailto:adamcameroncoldfus...@gmail.com] Sent: Monday, 25 February 2013 8:54 PM To: cf-talk Subject: Re: Apostrophes in email addresses Hey Kevin, one think I hope you got was that my blog post was not aimed specifically at you or anything in this thread, it was just the discussion was the catalyst for me to write something out.

Re: Apostrophes in email addresses
Pretty sure isValid() incorrectly flags emails with apostrophes as invalid.
There are two or three bugs with isValid() and emails.

Re: Apostrophes in email addresses
Pretty sure isValid() incorrectly flags emails with apostrophes as invalid. Nope, at least not with CF9 (checked last night before I posted). There are two or three bugs with isValid() and emails. I was about to ask if anyone had details on where isValid() might fail on e-mail addresses when I saw that Adam wrote up a blog entry in reference to this thread at http://adamcameroncoldfusion.blogspot.com/2013/02/email-address-validation-1-in-series.html which outlines a bunch of possibilities with tests run on CF10. As noted isValid() will work with the most common special characters I see in the wild (notably + and '). He points out a slew of others that fail though I don't recall ever seeing most of those in use after more than a decade in the industry (not to say they aren't out there, just very, very rare). He notes that there is a bug open on this with a will fix note so it'll just get better in future patches/versions. -Justin ~| Order the Adobe Coldfusion Anthology now! http://www.amazon.com/Adobe-Coldfusion-Anthology/dp/1430272155/?tag=houseoffusion Archive: http://www.houseoffusion.com/groups/cf-talk/message.cfm/messageid:354667 Subscription: http://www.houseoffusion.com/groups/cf-talk/subscribe.cfm Unsubscribe: http://www.houseoffusion.com/groups/cf-talk/unsubscribe.cfm

Re: Apostrophes in email addresses
Something tangential to keep in mind is BE CONSISTENT. I've come across numerous instances out there where different features on a site don't have the same validation. For example, the account creation process might accept an email address with a plus sign in it, but the password reset function rejects it. Whoops! Whatever validation method you choose, use the same one across your entire app. On 2/24/13 12:21 PM, Justin Scott wrote: Pretty sure isValid() incorrectly flags emails with apostrophes as invalid.
