Outgoing Mail not working

Hello , I am facing this issue since the day I have deleted Google Chrome Developer, earlier it was working okay. I don't know what I have done wrong but now I can receive email in my iCloud address but can't send any mail from iCloud. My server list is also empty and the error pops up while sending email is


Cannot send message using the server iCloud

The sender address abc@yahoo.com was rejected by the server p10-smtp.mail.me.com.


The server response was: From address is not one of your addresses


Select a different outgoing mail server from the list below or click Try Later to leave the message in your Outbox until it can be sent.


Sending from: abc

Go to Mail > Settings > Account, and choose the iCloud mailbox in the sidebar. Verify that the email address listed is a iCloud.com address and not a yahoo.com one.


Do you also have a yahoo mailbox listed on the same Account page?

If your iCloud account is not connected ( just an example ) , open mail application click on I cloud and send a mail from - iCloud address ( in the To - field type your yahoo address ) the mail will be sent to your inbox in your apple mail application a pop up appears , in this screen shot it is showing could not connect to outgoing server , thats the reason when connection doctor is opened SMTP for iCloud is totally vanished .You can apply same with yahoo say if IMAP or SMTP is not working . Simply click on always use this server to get joined .

And you will observe all IMAP / SMTP for yahoo account and iCloud account are showing green dots and joined to their respective server .



Compose a mail ( use command and N keys ) , fill up the credentials select a different mail address and click on try with selected server , in fact in mail preferences send new messages is automatic , that's the reason see the article Change Composing preferences in Mail on Mac - Apple Support

Send new messages from .

The email address to use when you send messages.

If you use several email accounts, you can have Mail automatically select the best address, based on the email address of the first recipient in your message, as well as the currently selected mailbox and message.


You can click on drop down arrow and choose the desired mail address like example1@icloud.com
