PSA: Apple Mail Incorrectly Parses Addresses in Signatures as Missing Recipients

With the release of macOS Ventura last month, Apple updated its stock Mail app with several long-awaited features, including the ability to remind you if you forget to add an attachment or recipient. However, it turns out that Mail incorrectly parses email addresses included in signatures as missing recipients.

"The new feature that is currently bothering me is Mail's new ability to remind me if I forget an attachment or recipient," writes 512 Pixels' Stephen Hackett, who was first to highlight the problem.

"Gmail and others have had this for years, and it's honestly great," he says. "It's just too bad that Mail doesn't seem to understand that some people put their email addresses in their email signatures."

"As you can see in this screenshot [above], Mail has started warning me every time I send a message that the email address in my footer has been left off the recipient list.

"This is a shockingly dumb catch on Mail's part because the application should know what I have set up using its own Signatures feature. It's literally right there in the app's own settings."

Hackett has filed feedback with Apple to hopefully address the problem in a future update, but until then it's worth bearing in mind that Mail will continually bug you to add any addresses in your signatures as missing recipients before it lets you send messages on their way.

I think it's worse than this. I'm getting bugged when I merely mention another email address in a message, because Mail thinks that address should be a recipient too? WHY? I often want to mention another email address but not include them as a recipient. There really ought to be configurable rules around all this...

I don't even understand the point of this feature. It's really useful when an email client notices you might not have included an attachment you refer to, but I'm struggling to think of an instance where I would want to include the email address in the message body of someone I'm actually sending that email to. There maybe be niche cases, but I'd suspect that 99.9% of the time that's not something you would be wanting to do.

I'm sure someone will come up with a valid example though.

It's difficult to believe that zero people at Apple put their emails in their signature.

So then the obvious question is, why wasn't this easily caught earlier?

Some people still print emails, or forward them to other people and not always is the 'From' field preserved in this context. It makes sense to have your address embedded in the signature.
