strange issue. On my Mac (and my wife's) running latest software (Venture 13.5) sending from Apple mail client my emails are not being sent. I used Bell Canada sympatico. Was working fine up to a fw days ago (I think). I've verified my settings all good. I deleted and readded the account. Still nothing. rebooted my modem. Nothing. But sending works from Thunderbird, and other email clients (Outlook, Edison). Interestingly, from my iphone both on wifi and off wifi, it works as well. I also tried firing up my VPN (I[m in Canada so I connected to Montreal) still nothing on the MAC. I am baffled. The outgoing server hs 2 ports 587 or 25. tried both. Nothing being sent. I am completely baffled. more troubleshooting. Works on my ipad as well no problem. I have a 2015 Mac running mail 14.0 Sierra 11.7 and it works fine. This looks to be issue with mail 16 or Ventura .. possibly last fix?
Got a tip for us?

It is a strange issue. Sort of resolved, sort of not. I test every day, usually I send to my sympatico.ca or protonmail.com emails. What I've found is if I don't put any message in (ie just a title .. testing!) mail does not go through. If I but a few lines (a <> b <> c) it gets sent. Unsing Thunderbird (which is ok but I liked Apple Mail because it used my Apple contacts, Thunderbird does not), I send a test message without any message (ie just s subject) and it is no problem. I also have Edison Mail which I am trying out, and again, a blank message goes through fine. So it cannot be smpthm server - it is Apple Mail IMO that is not sending a blank message. I've essentially stopped using Apple Mail on my Mac because i don't trust what is happening. Yet on my ipad or iphone, using Apple Mail with just a test message no body, it goes fine. I've checked everything on my Mac .. I try the ConnectionDoctor and it says everything is fine. My Apple mail only started doing this in the past month or tow that I have noticed. Give it a try (even to your own email) with a blank body then one with a few lines in the bady. Curious to know what you find
I was able to resolve this ( I hope, time will tell ).
The fix was to rebuild the mailboxes - I did this on both the Sent and Inbox, so I am not sure which one fixed it.
The rebuilding is described here

By chance I came across this same behaviour with my gmail accounts the other day. I made a jump to Ventura from an old OS and assumed it was a planned feature to prevent accidentally sending without content.
will give this a try later this evening thanksI was able to resolve this ( I hope, time will tell ).

By the way. I've been using Thunderbird on macOS for longer than I remember. I have it set up to include the macOS addresses as an additional address list. Can't remember it never working. It's gone through many updates of macOS and Thunderbird in that time without the need to reset anything.
I'm currently running macOS 3.5.1 and Thunderbird 115.2.0. The latest versions as of right now.
See the screen grab below.
it is very strange. I use the rebuild, any emails with no body don't go, as long as there is something in the body seems to work fine. I deleted my mailbox and readded it, try a email with no body, it worked .. once. It seems as long as there is something in the body of the email it will work. Very strange
