How to stop a Thunderbird pop-up warning.

more options

Can I stop the popup warning about sending emails to group with all emails in the TO: field. I've been communicating this way with an open email list for decades, and the popup is very annoying.

That worked, Thanks!!

Is that setting only for T-bird pop-up messages, or what else? I made it 20. What would happen if I made it 50, or 100, etc. Does it affect any other function?

Settings/General, Config. editor, the preference mail.compose.warn_public_recipients.threshold defaults to 15, so increase it to avoid the warning.

You can set the number as high as the maximum number of recipients per message that your mail provider allows. Do a test and you will see that the warning returns when the number of contacts exceeds the setting (just discard the message). I'm not aware that it affects any other function.

Just one more point about sending to multiple contacts, not with a mailing list:

Interesting. I didn't know servers do that -- esp. with all the spam going out with, I assume, using BCC.

My (I'm a member, I don't "own" it) mailing list is less than 20. Been around for over 25 years.
