Getting an SMTP Error

Mail
1

I installed eM Client on my MacBook Pro and on my PC running Windows 11. eM Client synced with my iCloud Email and all the Folders show up correctly in eM Client on the Mac and the PC.

The problem is that when I try to send an email I get the following error message: "Error Code: [SMTP] Cannot send message (Sending email "Test Email Nbr 2 " failed with error: Email recipient not accepted by the server.)” The SMTP and IMAP settings appear to be correct. The SMTP Port is set to 587 and the IMAP setting is 143, which is the same as my iCloud Account Settings. I have the same issue on the Mac and PC installations.

Any ideas on how to fix the problem? Thanks!

It means that address you are sending the message to is incorrect. Maybe you typed it incorrectly or there is some other issue with it.

You will find the message in the Local Folder Outbox, where you can delete it. If Local Folders are not visible below your other folders, you can enable them by selecting Menu > Settings > General > General > Show Local Folders. Click on Save & Close to save the setting.
