So... the mails have been sent, but I can't see them in the list of sent mails. I only know, they've been sent, because I get replies from the people, I've written, and in their replies, I can see the mail, I've sent to them. It's really odd.
I've also testet: I sent an email to myself, just with a five minute delay - and I received the mail (exactly five minutes later), but still, the sent email doesn't show up in the list of sent mails.
I am new to the "send later" function - I only found it yesterday after an upgrade to Sonoma 14.4.1. - but it seemed cool, so I chose to send a stack of emails late last night - all delayed to be sent this morning. These are all work related mails, so I am really worried that I can't keep track of them. They are nowhere to be found, except if I get answers from the receivers.
