I've had the same problem for a while on my new iMac 27 inch (Mac OS X version 10.7.2). Have added plus. in front of imap.mail.yahoo.com (so it now says plus.imap.mail.yahoo.com as the incoming mail server) and this worked fine for me.

Something's weird. Using the same network I can send via IOS on my iPTouch but not on Yahoo's outgoing server on my 2008 MBP with 10.6.8. I have checked the settings entered and deleted and re-added the same account copying the server info directly from the iPTouch but still can't send get an outgoing server connection on the MBP. Incoming is fine. I've tried every port, their old, new and others. Port 110 and SSL off works fine on the iPT, doesn't work on the MBP. Any thoughts?

I found this in another thread and it worked for me. I hope this works for everyone else
I've had this same problem. I tried a solution that has worked for Mail problems I've had with previous versions. It involves completely removing the Mail settings folder from User/Library/ (which will refresh Mail to its default settings and delete all account info) and then recreating the mail accounts. I'm not sure why this would work and deleting then re-adding accounts wouldn't, but maybe Mail doesn't clean up everything when you just delete the account in preferences.
Here's what I did
1. Move the Mail folder from User/Library/. This folder is hidden in Lion. To access it from the Finder, select the "connect to folder" option from the Go menu and type: ~/Library
Find the Mail folder and move it somewhere else (e.g. desktop or trash)
3. Open Mail and reconfigure accounts.
I haven't had the password boxes pop up (sending or receiving) since I've done this complete refresh.
Good Luck....I can now sleep because this was driving me insane.....Now on to the Iphone contacts problem

After suffering this myself for the last few weeks and it totally doing my head in (I have 10.7.3 on a Macbook Air and my Yahoo Mail (btopenworld) suddently stopped working and saying my username / password were incorrect - (I knew they weren't) I have today accidentally sorted it out without even realising!
I had tried every permutation of different server settings, unchecking SSL, etc, etc. all to no avail. I had deleted and tried to re-install my mail account countless times - still no good.
I just went into Terminal to turn off the automatic local backup from Time Machine and free up a shed-load of hard drive space that was being eaten into (I backup in Time Machine to an external drive like most folk and so don't need this "handy" new feature of Lion) and it has also inadvertently sorted out my Mail problem! Not sure if the 2 are related at all or whether it is just total coincidence but it now works so that's all I care about.
You can do a search for this online but the quick version is to open up Terminal (you have to be logged in as the main root user) type in sudo tmutil disablelocal hit enter and then type in your password (note it won't show on the screen and looks like nothing is being entered) - hit enter again and leave it for a while (depending on the size of your local backup - mine was 25GB and took less than a minute). The system then turns this feature off and deletes the existing local backup - here's a link to the instructions:
Not only did it reclaim 25GB of wasted Hard Drive space on my Macbook Air but then when I went back into Mail to try (once again) to set up my account, it worked flawlessly!
Like I said, this may be pure coincidence but it now works so no complaints here. I take no responsibility or credit for any of this as I know very little about Macs - I just followed the instructions above.
Might be worth a try if you are also having diffs with your Yahoo Mail and Mac Mail.
Best wishes all,
PS: Obviously if you do this and you are only backing up to your internal drive then you will lose your backup!

I had my sbcglobal account stop working suddenly in Mac mail in mid march. It has been shotty ever since. My MacBook pro is just over a year old. The mail was working great for over a year. Then one day it stops receiving mail and the stupid password rejected box appears. I to have tried setting adjustments, deleting and re installing the account. Nothing works for more than a day. It HAS to be a bug on the macmail because the iPhone and iPad work fine. I don't even have lion and it still doesn't matter. Seemed to have troubles after installing an update in mid march. One would think there has to be a solution. I've even had AT&T techs remote onto the computer and both of them said its a software problem on MacBook and not a yahoo issue. I have to agree this time with AT&T. Please apple fix this bug!!!!!!!!

I am running Lion 10.7.4 and am having all kinds of problems with Yahoo mail servers. The "mail" application just will not get along very well with the server. I am running a 27 inch iMac and had just a lot of trouble with mail. Tech is telling me and I also believe that it is the faut of the Mail servers at Yahoo. Does anyone have any idea or even how to find out what Yahoo is doing about this problem? Or would replacing the mail application with another, would that help and where does one find the mail application. Not in the app store??

The best solotion for this problem after facing it many many times ,,,,,,, is to leave it for one or maybe two days and it will be fixed automatically...... DON'T DON'T try to remove or re- assign to the yahoo server or ANYTHING else..... just leave it and don't look at it,,, it will become very normal,,,,,

I had this problem for the last 7 months. I'd had to just settle for using Yahoo POP which has been a complete nightmare with having to go through duplicate Yahoo mail between my desktop, laptop and iPhone!
I'm in the UK and have a yahoo.co.uk address so, naturally, I always thought that the correct imap adress was imap.mail.yahoo.co.uk.
I finally, finally, finally fixed this immense frustration of a problem and got my iPhone to start using Yahoo IMAP by using imap.mail.yahoo.com, along with firstname.lastname@example.org' at the end of my username for the SSL login.

I have noticed that my login details for outgoing mail didn't have .co.uk at the end of my username, so maybe that will help. Although incoming mail can be a bit slow, it is outgoing mail that is worst. I will see if this helps. Thanks. Both incoming and outgoing servers are yahoo.com.

I had an outgoing server issue. It stated I was offline for some reason but was still receiving email. I went into:
Outgoing mail server(select edit STMP server list from the pull down menu)
Select the Yahoo account
Click the ADVANCED button in the middle of the box next to Account Info.
Enter your Yahoo account password.
