Mail doesn't send emails

I have two accounts. Mail suddenly stops sending emails though i can receive emails from that account. I checked the email server and it is absolutely working fine. It throws an error and asks me for my password again and again. Whats weird is that this happens at random intervals. Can someone help me out.

Try deleting the password in Applications/Utilities/Keychain Access.
Try running Keychain First Aid.

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?

I've seen other posts that indicate sometimes an email
message can cause
a log jam. It can't be sent for some goodness only knows
reason and
then causes the process to abort piling up messages behind
it.
What happens if you remove the first (or first few) messages
in the que?

Mail doesn't send e-mail. Before yesterday everything was ok, but now it says that a copy of the message has been sent to "Sending messages" because the contents of the message cannot be send to server. What to do? IMAP should be ok.

My ipad doesn't send emails because it says the server does not allow relaying. What is relaying?

My ipad doesn't send emails. Message says the server does not allow relaying. What does that mean and how do I fix it?

Copied from here.
http://appletoolbox.com/2012/01/server-does-not-allow-relaying-email-error-fix/
How to fix
If this is an AOL issue, try these: go Settings > Mail, Contacts, Calendars > select your AOL.com account > SMTP from the Account Info Page > SMTP from the SMPT Page > make sure that the Server is ON, make sure that the Host Name is smtp.aol.com. Further make sure your username and password are correct and added in the Outgoing Mail server; make sure that Authentication is set to Password and make sure that Server Port is 587
If this is not an AOL email: go Settings > Mail, Contacts, Calendars > Accounts >Account Info > SMPT> turn off primary server, turn on other (e.g. AT&T) SMTP server.
Go into Settings > Mail, Contacts, Calendars > Your Account > Outgoing mail Server SMTP > Primary Server then turn Server ON and fill in both User Name and Password under Outgoing Mail Server.

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!

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.

My mac doesn't send emails since the last update

since I gave my mac the last update, it doesn't send emails, it receives emails, but doesn't send them. It says error: this message could not be sent because your account does not have a preferred outgoing mail server. Select an outgoing mail server from the list below.
But there's no list and when I go to preferences and try to select one, it doesn't do anything. Please I need to solve this problem.

Howdy mfl17,
Welcome to Apple Support Communities.
It sounds like you aren’t able to send email with Mail on your MacBook Pro because there isn't an outgoing mail server setup. Try using the article below as a guide for setting up your service providers outgoing mail server in Mail.

Mail can't send email from 123-reg accounts

Hi all,
I've got an issue with Mac Mail can’t send email from 123-reg accounts.
I know there is a lot of articles on simular matters and some I have tried out with no luck, others are just speaking a whole other language.
Any help would be greatly recived, here's my situation below:
Running a iMac 2.8GHz Intel Core i5 on OS X 10.8.3
I’m using 3 accounts on Macs Mail client, one is my iCloud account that is working fine and the other two are my 123-reg accounts that I use for business purposes. I’ve been working like this for a couple of years now and about 6 months ago I upgrade my operating system from Snow Leopard to Mountain Lion.
2 or 3 months ago I randomly got a problem where I was unable to send any emails from my 123-reg account, I could only receive emails. I checked my settings and they were all correct and unchanged so I attempted to delete them and recreate the account but with no such luck.
I then decided to check if it was a problem at 123-regs end and attempted to log into web mail. This worked and was able to both send and receive emails so eliminated that possibility.
I also have these accounts set up on my iPhone, so checked if there was any issues and everything was working fine. I then checked my iphone details and made sure the same was on my desktop and still no such luck.
I’ve tried out some of the articles I’ve found on here (the ones written in plain English) still no results. I’m not very IT illiterate and just wondered if anyone else has got any ideas, whether there is something specific with 123-reg accounts and Mac Mail?
Many thanks.

Thanks
I just had another hunt around looking at posts and discovered that it was because I recently changed to BT Infinity and they had a block on.
I didn't even think to question the ISP.

Mail does not send email

My problem is simply that Mail does not send email.
I have just migrated from iMac G5 to iMac Intel by using Migration Assistant. Everything else works just fine and I can receive email. However, if I try to reply, forward or send a new email message, Mail just does not do anything - no error message, nothing.
The fixes I have tried so far are removing the Mail plist file, repairing disk permissions and mailboxes. Of course, I have checked the account settings, especially outgoing server settings. I also reinstalled Mail application with Pacifist. None of this has solved the problem. I have tried sending email with Thunderbird and it works with no problems.
Does anybody have any suggestions how to fix this issue?
The OS is 10.4.8, Mail Version 2.0.6 (749.2/752.3), all the suggested software updates done.
iMac Core Duo 20" 2GHz Mac OS X (10.4.8)

Reinstalling Mail is rarely necessary or appropriate to solve a problem. It certainly cannot fix anything that could be wrong within your home folder or at the server or with the network, and may even introduce new issues if not done properly. Moreover, in Mac OS X 10.4 you don’t need Pacifist to reinstall Mail, you could also do it as described in the following article:
Custom installs in Mac OS X 10.4
Verify/repair the startup disk (not just permissions), as described here:
The Repair functions of Disk Utility: what's it all about?
After having fixed all filesystem issues, if any, if the version of the system software on your install disks is earlier than what you’re using now (and only in that case), then you must also reinstall the Combo Update for the type of computer and the version of Mac OS X you’re using, to bring Mail back in sync with the rest of the system:
About the Mac OS X 10.4.8 Combo Update
Mac OS X 10.4.8 Combo Update for PPC
Mac OS X 10.4.8 Combo Update for Intel
The above won’t solve the problem. It’s just to ensure that you’ve properly reinstalled Mail, which you shouldn’t have done, and which apparently you didn’t do properly -- the version of Mail on your system should be 2.1.1, not 2.0.6.
The original problem could be caused by some Launch Services cache or preferences corruption. The following article describes how to manually reset Launch Services -- the notes at the bottom of the article also provide information about the side effects of deleting each of the files involved:
Resetting Launch Services
If you prefer using a cache cleaning utility instead of following the manual procedure described in the previous article, this other article provides links to some utilities that can be used for troubleshooting and cache cleaning:
Resolving Disk, Permission, and Cache Corruption
It seems that the most appropriate utility for solving this particular problem is Tiger Cache Cleaner, but you may also want to consider other utilities, such as OnyX, or Cache Out X, which are free. Whatever utility you choose, be sure to read this first:
Side effects of System cache cleaning
As an example, this is how you should proceed with OnyX:
1. Quit all applications.
2. Launch OnyX and enter your administrator password.
3. Click Maintenance. In the Reset section, check LaunchServices database.
4. You may uncheck any other pre-checked options if you wish.
5. Click the Execute button.
6. Restart the computer.

AOL mail doesn't send .doc-files with Firefox

When using Firefox AOL Mail doesn't send .doc-files. Instead a corrupted file with a different size is sent. Any other file type works aswell as sending .doc-files with other browsers works...

I'm getting a similar problem. Snow Leopard Mail for me seems to be choking on large attachments - sending them, forwarding them, or even moving them from one IMAP folder to another.
My mails are getting through, but it takes a long time and they are dragging the whole system to a crawl in the process.

When I set up my mail I could send emails now a day later I can not send them but can still receive them ... I can't see what is wrong .. Any answers .

It's not a good idea to use a network disk for both Time Machine backups and other things. By design Time Machine will eventually consume all the space on its output disk, which will then cause problem for your other files. I'd store those other files on an external disk connected to the Time Capsule. The problem with that is that Time Machine will only back up files that are local to your Mac. That means that you'll only have one copy of the files on or attached to your Time Capsule.

Mail (Yosemite): Verify an account’s outgoing mail server

My mail will not send emails

My mail will not send emails. I can recieve them but it will not send. What do I do?

POP or IMAP? Make certain that you have your outgoing server, whether POP or IMAP, set up correctly.

IBook. Mac Mail. Can send email.

iBook running OS 10.4.11. Mac Mail. Can send email, but not receive. Slow to send, goes to Outbox first. Can send and receive email via WebMail. Any ideas please.

Is your Mail set up properly? It is possible that you have set up the wrong SMTP & POP3 servers.

HT5361 Mac OS X Mail 4.6 sends emails that other email clients don't recognize as attachments, but as embedded pictures. Mail 6.6 does not have this problem.

My Mac OS X (with 10.6.8 software) Mail 4.6 sends emails that other email clients don’t recognize as attachments, but as embedded pictures. When I receive emails from others, I do not see whole image either. I did change "rich text" to "plain text" in message format - no results.
My daughter has Mac (10.8.5) with Mail 6.6, which does not have this problem. Can I install 6.6 instead of 4.6 or do you know other fix?
Help, please?
Thanks,
Andrew

I've been having the same problem now for several months (at least 3-4 if not more). And the frequency of Mail quitting is increasing, several times in a few hours. And as with you, no particular message pops up before hand or not even the beach-ball spinning first and then quitting.
I too have been sending Apple the crash reports. However, I have not contacted Apple Support yet. Hoping to find the answer in this forum, but again, no luck.
If you have found a solution since then, please advise. Or if anyone else out there knows of this issue and can help, that would be greatly appreciated.
