issues with send mail pop-up
I'm using MAC OS 12.6.2 and "MAIL" Version 16.0 (3696.120.41.1.1) on a MacBook Pro (Retina, 13-inch, Early 2015)
Within "MAIL" I have connections set up to gmail, yahoo mail, and my website email server and "MAIL" download email and sends email from those servers. This has been stable for many years.
When I send an email, I have to select in the Drop-down which email address I wish to use for gmail, yahoo mail, or my website email server for each email sent.
Now when I wish to send an email by gmail a NEW subsequent Pop-Up has stated appearing asking to select the server to use, so I chose gmail in that case and the mail is sent without issues with the gmail address.
However, when I select from the drop-down in an email I wish to send my website email address the mail goes without the Pop-Up window showing which server to use, so I can't alter.
The result is that email I wanted to send from my website email address I selected from the dropdown within that email that particular email is sent without the pop-up showing.
The issue is that email on receipt shows as beings sent from gmail, which is causing issues.
My website email preferences for Incoming and Outgoing host servers are listed as the website server and have worked well up to now.
Is there anyway to ensure an email being sent using my website address uses that address, which I have selected in 'MAIL".
