I had this problem crop up in the past couple of days on a site I've been developing. We're due to launch on Monday and I'm going crazy.

I have two addresses entered in the admin > configuration > email options > "Contact Us" dropdown. The contact form used to be able to send to both no problem. The addresses are entered in the format OwnerName <[email protected]>, Webmaster <[email protected]>. I've tried deleting one address so there's only one in the dropdown to no avail. Both addresses receive email from other sources fine, and are administered in Google Apps. The contact form messages are not stuck in spam folders. I tried entering into the "Contact Us" dropdown another email I own on a totally different domain that's not administered by Google Apps, also to no avail.

I have email archiving turned on and the messages from the Contact Us form are showing up in the table in phpMyAdmin but they're not reaching their destination.

I checked the FAQ under problems sending/receiving email. I haven't changed anything in the store's email config recently, and order confirmation emails are going out fine to test customers with accounts so I'm guessing it's not a problem in the email config but rather in the contact form.

I can send email using admin > tools > send email.

I haven't updated ZC recently or done anything other than install (and then uninstall) Newsletter-Only Subscription. Oh, I also renamed the admin folder, but that hasn't caused any problems elsewhere.

At the same time as this I've had problems with order confirmation emails not getting sent to COWOA customers. I posted a message in the COWOA forum detailing that problem. Might they be related?

Thanks so much for any help you can give!
