This morning, I sent a message to a (now-defunct) Google group. (It was renamed.)
This evening, I see a “send rejected” message from the group server.
Off I go to the SENT folder.
I do NOT find the message there, where I used to find it in Mailbird.
Fortunately, I still have Mailbird. (I need it for simple things that emC makes difficult, at times.)
In this case, I needed the text of that sent message, so I could resend it to the proper Google group.
It should not have been necessary to do that.
