The IMAP server ... rejected the password for user ...

When I went to bed last night, Apple Mail (Lion, MacBook Pro) worked fine on my home IMAP server, as they have done for some time.
This morning, I cannot log in and I now get the following error message:
The IMAP server “...” rejected the password for user “...”.
The password is definitely correct. I have typed in the password repeatedly (although it was already correct) to no avail - I just get the same error message again.
Since then, I have tried:
my Linux laptop using Thunderbird
my Xoom (running Android ICS) and K9
my SGS2 (running Honeycomb) and K9
my iPad 2 using IOS Mail
Roundcube (webmail client) on the MacBook Pro itself (so no connectivity issues)
and all still work perfectly. There have been no changes to my mail server (which is Dovecot running on Debian Squeeze, which has been running flawlessly for years) and none to my MacBook Pro (unless they were silent).
I have tried deleting all the relevant items from my keychain, but that has made no difference either.
Any ideas because I'm stumped?

Since I posted this, there has been more, but slightly different, weirdness.
In the middle of a session yesterday, Apple Mail started to do something different. When I typed in the password, it briefly worked (downloading one or two messages) and then the error dialogue box popped up again so clearly the password was always correct.
A short while later, it accepted the password and stopped complaining until ten minutes ago. This time I only had to type in the password once and it is working at the moment but who knows how long for?

Mail: The POP server rejected the password for user

I am completely unable to use Mail.
I keep getting the "The POP server rejected the password for user" on two of my accounts.
The password has not changed and I have entered it correctly.
The accounts just will not go online.
This started yesterday when an old machine accidentally fired up mail and tried to connect using the same user details. Since then, my MacBook Pro is not able to connect to my mail.
My iPad and my iPhone can. There is no problem at the server or the ISP. I have also run the Keychain repair utility.
Please can you advise how I should fix it? Plist? Define the accounts again?
Any ideas welcome.
Thanks

Sorry I can't be of help, I know of others with this problem. In my case I have two accounts that don't work in Mail whilst the other accounts do. I suspect it may be a bug as I've been looking for a solution for sometime. My current solution is to collect the mail on those accounts with an XP netbook which is probably not very helpful!
I have also tried the Keychain repair and at least for a short while it looked as if it had fixed it.
Any ideas anybody before I go through the hassle of reinstalling everything?

Can't send mail, get message: the smtp server rejected the password. I tried lock and unlock keychain. I tried unlock captcha. Gmail works okay, it is Mail that does not. Help!! :(

Hi
You need to check with your ISP whether or not the send mail server (SMTP) requires a password. Some do, but many do not. When you know the correct password to send mail, then you need to tell Mail as follows:
Mail menu > Preferences > Accounts > Select the account
Click on the Outgoing Mail Server (SMTP) combo box, and select Edit SMTP Server List...
In the Account Information tab put the server name
In the Advanced Tab, set up the authentication information from your ISP.
Good luck

Hello Linds,
No need to redo everything.
Is your gMail POP or IMAP?
It's likely just a Port# or authentication method not really the Password.

The POP server rejected the password for user

Hi Im new to this forum but need help! I can usually fix most things on my mac but the last 2 weeks mail will not recieve any incoming messages as is just says "The POP server “mailin.macmail.com” rejected the password for user “****”
I have looked at other postings and tried keychain etc but nothing will work. This happens with 2 accounts one from macmail and one from NTL (my ISP) I can send mail fine (no password) and can go on to webmail and get my messeages fine on both accounts.
Does anyone have an answer for this?
Many thanks

The iCloud server rejects my password

As of the past 36 hours, whenever I try to get (download) my mail ("Mail" via iCloud) a pop up window appears that states...
The iCloud IMAP server “p02-imap.mail.me.com” rejected the password for user “me”
Enter your password again or cancel.
I enter the valid password (which was functioning just a few days prior), yet once again the server rejects my password. Hence, I haven't been able to retreive my mail now for going on two days.
I have not changed my password or any other data (related to iCloud or the "Mail" program in a about a year. If I recall correctly I had updated the Safari program and I think a Java or Security item the previous day.....
Can anybody (please) supply me with some information or tips on how I can retreive my mail and get this #%& program functioning properly again?

Thanks Csound1... that worked and then on a hunch I immediately opened my 'Mail' program clicked on get mail and entered the same AppleID and password and this time.... for some incredible bizarre reason, my mail program worked and displayed all of the last few days mail.
Thanks again.

Intermittent "The mail server rejected the password" on SBC-Yahoo

I have Mail set to automatically check email every 5 minutes from an SBC-Yahoo DSL line.
*Every day* when I come home, the "Server rejected the password" error dialog is waiting for me. Of course, the password is correct. When I re-enter it, Mail downloads the mail correctly.
This problem seems to occur more often since I switched over from the old prodigy.net to the sbc.yahoo.com servers.
While I sure wished that Mail was not totally boneheaded in handling the occasional failed POP connection attempt, I wonder whether:
1. I am the only one having this problem
2. It's a Yahoo problem
3. Is there a way to fix it?
TIA

I am having the same problem. I have to re-type my password for two POP accounts each time I start MAIL. It doesn't hold the SMTP passwords either.
Once I go into the preferences and re-type them it will connect fine until I restart MAIL and I have to start all over again...I too wonder the same things!

My mail has stopped receiving anything and is saying the IMAP server username and password is wrong but I haven't logged out or changed anything?

My mail (hotmail) has stopped receiving emails and keeps saying the IMAX server username and password is wrong when I haven't changed anything?

Hello ,Marshyy96
That is not good, lets see if we can get your email back up and running again. Take a look at the article below to go over the settings to just make sure nothing is out of the ordinary. You may end up needing to remove the email account and add it back in.

More detail needed....
For example, a domain isn't authenticated, a user is authenticated. Are you saying that ALL users for one domain can not authenticate? Has it ever worked? Have you changed anything? What do the logs show? Is the user ID entered in the POP client a valid short name for the user in WGM? Is mail enabled for the user?
Please post details if you want help.

Pop-server rejecting my password

i have an e-mail account at netidentity.com. i've had it for about five years. it's been configured within mail.app flawlessly since that, most of the time. but from time to time, i am repeatedly prompted for my password. the popup says that the pop-server rejected the pasword for that account, and please enter it again. if i enter my password, it's rejected and the prompt pops up again immediately. this can go on, and i have to cancel, leaving the account inactive for some time. the situation usually resolves in a day or two, but meanwhile, i'll have to check my mail using their not at all that good webmail service.
this time around (yesterday and today) this situation occurs when i'm at home. using only an airport express and the modem, no firewall. at work, however, there are plenty of firewalls, but i could get my mail as expected. at other times though, this would happen no matter where i'm at.
does anyone have any clues as to what i could be doing wrong? or is this just the internet weather conditions we live under?

POP server reject the password for....

Dear All,
I am trying to set-up the mail client of my macmini runing Lion Server (on the same machine), but I get the message
"POP server reject the password for user "John".
As I am not an expert on Lion Server, can anyone please tell me what I am doing wrong.
The loggin account name on the server is "John", PW is "1", domain is "exemple.jp"
The mail address is concequently [email protected]
1st: is the POP server PW different from user loggin password?
2nd :is there a place on the mail pop server for user password.
3rd: how does this work??
Thanks for any help.

Do you have one, two or more entries in the left colum of Mail.app for your mail server(s)? That is, do you have your Mail.app set up with either a btinternet entry, with a btyahoo entry, or both? Or more?
I'm guessing that you might have one account (btyahoo?) listed for incoming (IMAP server) mail, and with the outbound (SMTP server) mail is configured and named btinternet.
Based on what little I see posted, it looks like BT uses both btinternet and btyahoo, but I'm not exactly clear on how they have their stuff set up, and their web set gets helpful and tries to help configure my mail — I don't immediately see a single web page with the mail server set-up details. The BT email client set-up starts here.

Error msg: Sending of password for user did not succeed. Mail server responded: Not enough disk space - what's the deal?

I've been checking my email via webmail for a week and am back in the office today. Fired up Thunderbird, expecting it to pick up all my email, but it gets nothing and tells me…
Sending of password for user [email protected] did not succeed. Mail server pop.ipower.com responded: Not enough disk space
Haven't seen this particular error message come up in searches via google and at mozilla. There's definitely disk space on my machine. I'm running TB on a Mac (OSX 10.6.8). Disk Space options under Preferences > Advanced let me assign up to 1024 mb for the cache, which I've done, and cleared.
Has anyone encountered this before? Got a solve/troubleshooting process? Thanks!

Thanks. I do compact regularly (TB prompts me to) and did it (several times) via Preferences today to try and get TB past this error message.
Also went thru and Trashed + Empty Trashed as many messages as possible from the inbox, just in case. Still no-go.
