If you mean sending from iCloud (since you are posting in the iCloud forum) then, no, you can only send using iCloud's SMTP (outgoing) server with your @me.com address as the 'From' address.
You may be able to set up Yahoo mail as a separate account in the Mail application: but you may need Yahoo Plus to access Yahoo mail other than on their webmail. You'd need to check that in their Help.
Listen I do not have any problem with the I cloud at all. When its come to setting up the..... Outgoing
mail serve (smtp) for yahoo I have tried every thing even I changed any other settings in my email accounts.
But doesn't responds. Just some one tell me please for yahoo account what should I put for Server Name and
Description ??? I already tried the (smtp.yahoo.com) or even this one. (smtp.mail.yahoo.com)
I believe do something wrong here . Is all of
this make sense what I try to tell you ? Im just so confessed
(It wont let me send any emaills)
Thank you for your response!
First of all, this is not an iCloud issue. It has nothing to do with iCloud. It is merely a setting for the Mail application.
Note: You require a Yahoo Plus ($19.99 USD per year) account to use POP3 and SMTP. This service is not available using a free Yahoo Mail account.
Go to the link below to find out the proper settings for use with Mail to use Yahoo's incoming (POP3) and outgoing (SMTP) servers. I also suggest you use port 587 for your outgoing (SMTP) server as most ISPs block outgoing mail if you try to connect using the default port of 25.
