Leopard and Mail won't send emails, same exact setting working on my PC

I am trying to set up my new MacBook to use the Mail app (or Thunderbird, or any mail program at this point). I can get mail, but can't send mail. I've read lots of discussions on here about port numbers, etc. Here's my problem - all my setting work on my PC laptop in all locations. Same settings don't work on my MAC with mail or with Thunderbird. And Eudora on my Mac just freezes...I can't test the same settings on my desktop mac cause it's a company machine. Ideas?

Did Earthlink have you try using their authenticated SMTP server?
If not, try changing Earthlink's SMTP server settings to the following:
SMTP Server: smtpauth.earthlink.net
Server Port: 25 or 587. Assuming Earthlink is your ISP, 25 should work.
Use Secure Sockets Layer (SSL): Off or not selected.
Authentication Type: MD5 Challenge-Response. Not sure if this authentication type is available with 10.2 and if not, select Password.
User Name: Your entire Earthlink email address.
Password: The password for your Earthlink email account - the same password used to check the incoming mail server for new messages.

TS3276 Mac Mail won't send emails with signatures

My Mac Mail won't send emails with signatures. I get the "whoosh" sound and they show in sent mail, but the recipient doesn't receive them until I take off the signature and resend the email. Without a signature, it is received. It never used to be a problem, but started this past month. Please advise!

Mail won't send emails

Tried to set up my yahoo account using mail, and while it will receive emails fine, it won't send them. When trying to send an email I get the spinning wheel next to the 'sent' folder, but after a while it tells me my password is incorrect and asks me to re-enter it. However re-entering the password just brings up the same box. I have the same issue on with thunderbird, when I try and set up my ymail account, it tells me my password is incorrect even though it is not. Thunderbird runs my hotmail fine, and mail on my iphone runs my yahoo fine.
Any help with this issue would be much appreciated as it is extremely frustrating

Hmmm…then try creating a new User account for testing purposes, setup Mail there with the same settings and see if the password is accepted there. If it is, that would seem to suggest that your Mail preferences file is corrupt, and the only way to be certain and correct it is to remove the current one and create a new one.
If you have to do that, there are different steps depending on whether you have a POP account, an IMAP account, or a combination of both, so let us know before you do anything so we can give you the correct instructions.

Now Mail Won't Send eMail (self imposed password)

Apple's Mail has a known bug that it deletes your mail passwords sporadically. Now Mail has not only refused to pick up email while deleting the password, but has "deleted" the non existent password to send email.
Before when Mail deleted the password I could put it in again (and again) until it caught and worked again. But there is no outgoing email password, the server does not require one. If I put it a password it doesn't work because it can't. Does anyone have experience with this problem. It did this the first time last week and it went away after a few hours. But I do need to send email for my business.
Is there anything to do other than wait for it to go away again?
Anyone care to recommend a commercial email program to replace Mail? I have a few thousand emails in a few dozen folders that I would like to import. Is there any?
History, read this before asking any questions.
Mail has for years sporadically deleted incoming pop account passwords. They are deleted in Mail. The copy of the password in Keychain is still there, but Mail will fail to pick up your mail and ignore Keychain. This has been posted many times in this forum. The problem occurs randomly and goes away after awhile, but will return. If one has several pop accounts on the same server, some, all, or none of the accounts will have this problem at any given time. When the dialog pops up requesting the password the best thing to do is click cancel. Mail takes the account off-line. After awhile click the icon to the right of the "inbox" and click the button "Take all accounts online." It will usually work again. Sometimes it will not work. Delete the Keychain entry and put in (the same) password the next time the dialog comes up, check the "save in keychain" box and click okay. Usually it will take in then. Not sure why, but if you put the password in the first time the dialog appears, it almost always fails. some users have surmised that Mail sees any delay in the mail server response as a failed password and this problem is more frequent with webmail accounts than email accounts.
After ten years of OS X Mail use, and a year of off and on receiving problems, I have only this week started to have problems sending email. I have checked with my provider and there is nothing wrong with their servers and they have not suddenly changed the required Mail setup.

I blocked out my local IP address, it is correct though.
The last READ from the server does not contain any error that I can see, but I don't know what one would look like. At this point the dialog is up requesting a password.

Apple's Mail has a known bug that it deletes your mail passwords sporadically.
Sounds awfully definitive. Has Apple verified this for you?
I will, from time to time, be prompted for a password. I cancel and try again five minutes later. 90% of the time, it works fine the second time. The other 10% of the time, I have to wait for an indeterminate amount of time, sometimes several hours. This indicates, to me, that there was a problem contacting the server. I used to see similar behavior with Eudora years ago before I switched to Mail.
I never have to actually re-enter the password. At no time have my passwords been deleted.
None of this answers your questions, but hey... you come on here and cry "bug" and you're going to get challenged if others aren't seeing a bug.

Switched ISPs and Mail Won't Send

Just switched internet providers (Time Warner Cable to AT&T). Internet and incoming mail work fine, but outgoing messages won't send. My outgoing mail server is my sever at work. How do I get my messages to send?

AT&T might be blocking all network traffic destined for port 25 of any destination, except for their smtp servers (I don't have them, so am unfamiliar with their policies -- but if you used to be able to send, that's what I would suspect). Talk to your I.T. guy at work and see if your work's server can accept incoming on a port other than port 25, like port 465 or port 587.

Mail won t send emails with gmail account.

Mail app was working perfectly and suddenly it stopped working
All i have configured is my gmail account with IMAP, it receives the mails perfectly but i cant get any mail to leave my outbox. I simply get the timeout error with the try again or edit settings message.
I rechecked and recreated the outgoing mail server with the settings from google, and it still happens.
I tried rebuilding the outbox as i read on these forums that it might help, but it didnt.
What else can I do?
thank you
Charles .

Hi.
You could try moving the preference file to the trash.
The file is called com.apple.mail.plist
and can be found in the following folder: username -> library -> preferences

Mail doesn't send emails after Leopard upgrade!

Hi everyone..
I am wondering if anybody is facing this as well..
Since I upgraded to Leopard, and Mail retrieves both of my emails on Gmail and .Mac inboxes very well and stable.. But, when it comes to sending, it doesn't.
It keeps on taking forever to finally give me this error "The connection to the server “smtp.mac.com” on port 25 timed out" and of course, I have checked everything the error told me, and no it's not my fault. I thought .Mac mail servers are down, but, no.. My outbox mail lies there for about three days now and no clue how could I help mail succeed sending them.
If somebody faced similar problem, and might have a solution for it, please help.
Thank you.
Mark

When I try to delete an e-mail . . .
Error message is as follows:
"The IMAP command “UID COPY” (to Deleted Messages) failed for the mailbox “INBOX” with server error: Error in IMAP command received by server.."
This is my first Leopard bug. The Mail program cannot delete messages using IMAP. Mail worked fine using Tiger, so that is lame. Now I have to use Webmail to actually delete a message. Any thoughts?

Safari and Mail won't open in Snow Leopard

Any else having this VERY frustrating problem of Safari and Mail not opening. I've installed Snow Leopard and downloaded and installed the 10.6.1 update. Then when I try to open Safari, it says, "You can't use this version of the application Safari with this version of Mac OS X. You have Safari 4.0.3." When I try to open Mail, it says the same thing. I downloaded Safari again, and it won't even install it saying, "Safari can't be installed on this disk. This update requires Mac OS X 10.5.8 or newer." But I have 10.6.1.
Help. Anyone? Please?
Thanks

HI,
Try launching Safari and Mail from the Applications folder. If it works, drag the Safari and Mail icons off the Dock. Just drag straight up. They'll go poof.
With Safari or Mail open, select the icon in the Dock/Keep in Dock.
If that doesn't help, locate these files.
com.apple.Mail.plist
com.appple.Safari/plist
Drag those files to the Trash, empty the Trash and restart your Mac.

Double check your contacts email, and if its incorrect, go to their contact and change it and save it or you can delete the email you put in, and manually type it in.
Hope this helps.
How would that help the original poster?

Hello Bill,
Who is your eMail provider, the part after the @ sign?
In Mail's Window Menu, choose Connection Doctor, any red dots for status, if so what is the message?
Then click the Show Details button & Check again.

We upgraded or computer from os x to Snow Leopard 10.6.3 now our icons for safari and mail won't open

We upgraded or computer from os x to Snow Leopard 10.6.3 now our icons for safari and mail won't open

Drag the icons from the Dock, go to the Applications folder and drag Safari and Mail (one at a time) to the Dock. Don't release the mouse button until the adjaxent icons move out of the way for the one you're adding.
That should compensate for the updates to Mail and Safari introduced with SL.
