Cannot send Mail via SMTP

Cannot send Mail via SMTP

Hello everyone,

i created a new account at Zoho and wanted to use it via Thunderbird and my cellphone.

On both, i get a connection error on SMTP server when trying to send mails, though IMAP Email receiving does work.
The screenshot shows that my SMTP configuration is correct. The errormessage says, there was a timeout.
Id be pleased if you can solve the problem!
