I have IMAP accounts in Mail connected to two different hosting accounts.
All of the accounts in Mail can receive emails but the email connect to one hosting account can't send emails from Mail.
As its' one email account that won't send I'm assuming it's that account's SMTP settings.
My ISP have told me that SSL needs to be deselected. If I try to deselect it it selects straight away.
To stop this I'm using the custom port 587.
I have Authentication set to password.
The connection Doctor shows everything connected.
I have read all posts about this but still can't get this to work.
Can ANYONE offer any advice how I might get this to work.
I've used Macs for 15 years but I'm seriously thinking about moving to PC now.
