Can receive Comcast mail with evolution but cannot send.

The SMTP settings record more digits when clicking the Server Configuration apply key.

Sending ([email protected]:tenz222) port587

After clicking apply, receive a "Error while sending message" host lookup failed etc

When rechecking,the sever settings are, ([email protected]%253atenz222)

Attempted this process many times with same result.

Now need to be proactive and ask for help.

Will phone for help anywhere, anytime in USA.

Thanks
