problems sending one email to multiple recipients

Just started having problems: I can't send one email to multiple recipients. When I tried to write an email and added 3 recipients - it comes up with the message that the address 'does not appear to be a valid email address' although I verified the correct email. After that, it tells me that 'the stmp did not recognize the following recipients'. The weird thing is that the email will send when just sent to individual recipients.

I haven't updated anything or done anything different. I can't figure it out. Any solutions?

what changed...?

Monterey you can try turning off some of these new features and see if it makes a differnece:

Open mail app select Mail>Preferences>Privacy disable “Protect Mail Activity” / “Hide IP address” / “Block all remote content”

Maybe I updated to Monterey 12.0.1, since this is the version I have.

***UPDATE**** I wasn't able to figure out the problem, BUT it self corrected itself. I decided to do a test in the PM, and it worked. I can only assume that it was some issue with the company that hosts my websites in which my emails send through. I am just happy it is corrected. Unfortunately, I will be no help to others having a similar issue since I just got lucky with a self-correction.

Well, "try again later" —is always sage advice for glitches, one off's, server issue, etc before you pull the fire alarm...

I will add your post above " Monterey 12.0.1"— the current stable release of Monterey is macOS 12.3

Maybe your list has in incorrect character in it.

Check each email in the list against the known working individual email addresses. Check address separators or spaces in the list.
