I've been running eM Cient on my Win 10 laptop for years with no issue.
Today I get the following error message:
smtp server does not support authenticationHere's a screenshot of my error log
Note the line I copied below:
"MailClient.Accounts.SocketException:Connection failed due to the following reason:
An attempt was made to access a socket in a way forbidden by its access permissions 22.214.171.124:25"
Incoming mail comes in OK - HELP
