Warning when replying/forwarding and your sender address is not in the list of recipients
-
When you're replying to an email and your address is not in the list of recipients you may be exposing an email address to others that you don't want to be exposed. Examples:
- you have more than one email account configured in Vivaldi and accidentally changed the sender's address from account1 to account2.
- someone sent a mass email and added you as BCC. If you make a reply-all, the people that didn't have your email address will now know what it is.
- you got an email on a different alias than the main one used by your account (for example, addresses like [email protected], [email protected] and [email protected] are all delivered to the same inbox - you may have gotten a message at myaddress and are now replying as my.address because that's what you configured on Vivaldi)
My request is that in any of these scenarios, when the Sender's address of the message being composed is not in the recipients list of the original message then a tooltip warning displays near the Sender's address with something like
This email address is not in the original message's recipients list (maybe you got it as BCC or using an alias). Make sure you want to share this email address with others -
I find this the most relevant where you have been on BBC – as it is easy to mistakenly reply to all (because that is what I normally do) instead of only to the original sender.
There is also another variant that would apply for Gmail (and others) who allow the use of "+" in addresses to create unique incoming email addresses.
From your example above this could be mail received at [email protected] or [email protected] where you are then replying from [email protected] .
