E-mail suddenly won't send. I've been using this account on this iMac for years.

When I try to send, I get an error message that it can't send mail on this server. I've checked all my settings and rebuilt the mailbox. The settings are the same as on my iPhone, and the phone has no problem sending. I can also send using my account directly on the ISP web site, so my mail account is working and the passwords are correct. When I use the Connection Doctor, it says it has no problem making connections (all green lights.) Any ideas?

YOU ARE A LIFE SAVER! I reinstalled the program and everything. THANK YOU! THANK YOU! MY HERO!!!

Outgoing mail suddenly won't send

For years I've had a POP account, using Mac Mail to send and rec ATT/Yahoo mail. In the past week or so, my account has decided it won't send anything and says the server can't be accessed. However, incoming mail works fine, and my wife's POP account on another log-in with ATT/Yahoo mail also works fine sending and receiving. I tried deleting my account and starting over, which allowed me to send one email successfully. Next time I logged in, though, it was back to balking. Any ideas?

Hey, I found a fix for Mac who use ATT / UVerse / Yahoo!!
The directions that are given by ATT are only good for setting up an ATT e-mail account on a Mac. If for some reason you need to use another provider (gasp!) their settings will NOT work. The workaround is to have an agent open up port 25 so that you can use another outgoing smtp server. In my case, my provider is fatcow.com (really!). So once port 25 was opened up I could add smtp.fatcow.com as an outgoing mail server. In that case, they do require password authentication. Your case may be simpler and you may not need authentication at all (Inisight, WOW, RoadRunner etc.)
So it is possble, despite the dearth of information on ATT's UVerse web site. : P
Cheers,
: )

My new iphone 4 receives mail but won't send it

my new iphone 4 receves mail but won't send it..

Depending on what account your using, you may need to enter a password for your outgoing mail server, same password as your incoming mail server - go back into the mail account and check.

Mail won't send but Connection Doctor says smtp account OK.

Mail won't send but Connection Doctor says smtp account OK.
I can receive mail but can't send it from Mail 3.5. Same problem on a wired G5 and on a wi-fi MacBook (using the same account), so not hardware related. Worked fine 'till today - I didn't change anything in between times. Incoming mail no problem. Tried mail rebuild, keychain first aid, deleting the account, repair disk permission - doesn't help.
Mail's connection doctor says "smpt.xxxxxx - connection to server succeeded, no login required."
Anybody any ideas? Thanks, N

Been having the same problem for a few weeks now. This has been working just fine, and all of a sudden - nothing. The update to 10.5.6 didn't do anything to fix this either.
I've spent numerous hours on the phone with the Apple support. Seeing as the two other accounts that I have configured work with no problem, they say that this is a problem with the provider which is also the ISP. I then called the support line for the ISP and informed them of this and they say that it's a problem with the software.
Interestingly, if I send a message to somone with the same ISP, the message will go. But I can't send a message outside of the provider. Does anyone else have this problem?
Also, from another forum, they suggested rebuilding the LaunchServices database. The Apple support didn't see what that would do. But I tried it anyway and the problem still exists.
Another intesting thing is certificates. It's only happened twice, but I've received the message saying that Mail can't verify the certificate XXXXX which validates the identity of the smtp. Anyone else get this? I thought perhaps I could delete the certificate and it would magically reappear. But when I go into KeyChain, the certificate is listed only under System Root and I can't delete it.
ideas?

I am now able to receive emails in MAIL, but Yosemite's Mail program does not recognize any of the server's connections that have worked for years! What do I do next?

Yesterday, I was unable to receive emails from Google but was able to receive them from another server - but then receiving them began to work again - but now I am unable to send any mail - Yosemite's Mail program does not recognize any of the server's connections that have worked for years, ! What do I do next?

My imac's mail programme won't send my mail!

The imac has my hotmail linked to it, and has never had any problems but suddenly it won't send mail. It says it timed out when connecting to live.com. I have tried reinstalling the hotmail account but it didn't fix it. Does anyone have any ideas how to fix this? My iphone is working fine with the account and it also works with hotmail over the internet. I am stumped!

I've had exactly the same issue over the past couple of days and this fix has just worked for me (thanks untzy) but I guess it hinges on you being with BT.
1. Login to your BT home hub manager (this can be done using the router address located at: system preferences/network/advanced/TCP/IP)
2. Input your router address into the web browser search bar
3. Once on the access page you will need to input your wireless admin password (found on the back of your router)
4. When you are on the home page, you will need to follow the following steps to change your device name:
5. Select "A-Z" in the top right section of the page
6. Click on "Home Network" from the available list of options
7. Click on the Device in question (it should be showing as connected - I identified mine by the mac address, although it was named as 'unknown')
8. Under Device Information, enter a new name (be sure this is memorable in case you need it again)
9. Ensure Always use this address is set to Yes (it is by default)
10. Click Apply.
You will then need to restart your computer - after this, hopefully the problem will be resolved....

My macbook pro suddenly won't send emails.

They sit in my outbox. Please can you help.
This suddenly happened this morning when I tried to send a video. I cancelled that message bit it froze the whole thing although one message seems to have got through.

My Macbook Pro suddenly won't read my 750GB WD Elements Hard drive.
If I'm not mistaken, this drive is bus-powered. MBPs seem to have frequent problems with bus-powered drives, probably because they don't provide enough power on the USB bus.
In disk utility though it says it is a 2.2TB hard drive
It is possible that the drive or USB interface are damaged. However, it is too early to decide. You need to connect the drive to a desktop machine (Mac or PC), or provide more power to the drive (with a power supply, if the drive accepts it, or a USB Y-cable and a USB power supply, rated 1A or more).

Mail replies won't send in OS 10.8.3

Replies to mail messages that have a link within the message won't "send" unless I delete the link and any other messages beneath the message I am replying to . Message hangs up in activity window . I've checked with my ISP and all is fine there. My older iMac running OS 10.6.8 mail works flawlessly . What is going on here? New messages "send" o.k. So I'm clueless and bummed about what appears to be some mail glitch on ML.
Also, what is this new "envelope shaped" mail format with the blue border ? Is there some option to change the format back to the regular " letter shaped" mail format ?
Thanks for any help !
Carolyn. a.k.a. gladys2

So far, no big change, but I have figured out how to circumvent the problem by just deleting anything I'm replying to other than the last message in a group of "back and forth" mail. (if that makes any sense). Its a minor hassle, but I'm not willing to risk messing up things by getting into areas where I'm not comfortable.... like messing with the Library.
I did run Repair Permissions a couple of times after I had tried everything else that was obvious, shut down, unplugged and restarted. I also sent an e-mail to Apple support and told them what I thought about Mail in ML.
It comforts me somewhat to see that there are a lot of folks out there with the same type problems, each with variations on the theme ! :-)
I do appreciate all you suggested. If you come up with any other easy ideas, let me know. You are a good guy to show concern and try to help !

Mail mess -- won't send

I'm switching from Thunderbird back to Mail, and I've encountered a problem - it won't send anything. When I click on "New Message" or "Reply" or anything that would send, nothing at all happens. How can I fix that? Thanks!

Mail periodically won't send.

Three or four times a day Mail won't send an email. The other 40 or 50 attempts to Send Mail work fine. The whirling icon spins beside Outbox, and eventually (maybe three minutes) I'll get a message that Mail can't send the message using the selected server. If I click Try Again, it will typically send the message.
When Mail doesn't present me with the dialog, I have to quit the application. Upon relaunch, I see an email in the Outbox and I can select it and send it, typically without an error.
This is a sporadic problem, appearing with Leopard, and remaining consistent through all incremental OS upgrades.
I use Comcast as my internet provider, and my email is hosted at GoDaddy.
I have seen other posts with similar problems, but no solutions.
Ideas? Thanks.

Greetings,
It's very doubtful that it's the OS - I have 5 of my own machines, and hundreds at work, and there are no issues with sending mail. I move around a lot from city to city and from state to state and I have yet to have a problem of any kind, much less mail.
Do a Repair Permissions, and/or trash the .plist files for Mail, clean out the startup items in System Preferences > Accounts > Login Items, and restart the computer. You could also do a "sudo periodic daily weekly monthly" to clean out the cache.
Some fools leave their computers on all the time, and this will shorten the life of any computer, or anything in general, for that matter. I shut my machines down if I'm going to be away from them or more than an hour or so. I will leave them on over night once a month to run the scheduled maintenance.
If you leave your machine on all the time, corruption can result in various parts of a machine, it's not usual, but it can happen.
I run nothing out of the ordinary, like application enhancers, APEs, GROWL, other haxies or any of that junk, nor questionable software, like open source junk, and most of it is just that.
The only true way to determine where the problem lies is to erase the hard drive and start fresh. Just use software like Office 2004 or 2008, the iWork and iLife stuff. Adobe CS stuff should be Ok, as well as any from the major software folks. Load no junkware.
Try your email and see if you still have issues. You can add software a little at a time and see when it breaks.
To say an OS is bad doesn't even make sense to any rational person - there are millions of satisfied users out there that never come to these forums, so that in itself should be a wake up call. There are software issues, from time to time, but by and large, those issues are addressed pretty quickly and Apple would never let something like that fester without addressing it. That's why we have updates from time to time. Most of the issues here, are self generated, one way or another.
Cheers,

Mail client won't send .Mac mail

Hi all,
Hope you can help. I'm suddenly having problems sending outgoing messages via the Mail client in 10.3.9. Mails go into the outbox and then a few mins later I get a prompt box stating:
+"This message could not be delivered and will remain in your Outbox until it can be delivered.+
+The SMTP server “smtp.mac.com” doesn’t support authentication. Please check your account settings and try again."+
Any ideas?
Thanks in advance

Hello Michael
I think there might be a problem with the dot mac server. There are others experiencing the same problem posting at the .Mac forum.
As For your Mail's complaint that the server cannot use authorization, well, the dot mac server does use it, so that message is rather odd.
Try again later and it may be working.

After years of use, AOL mail now won't send mail using firefox

I have used AOL with FIREFOX for years. However, now it won't send mail, the send button, and the reply button are dead, inoperative.
I have updated FIREFOX, it didn't help.
I can't think of anything that has changed, although something no doubt has

Mail freezes, won't send

I know there have been several threads recently about Mail not sending, but my problem did not seem to match up with anyone else's, so perhaps I'm alone in this or there's some simple solution I've overlooked.
I have three Gmail IMAP accounts running through Mail; all have behaved fine until recently. Now several (related?) problems are occurring:
1) After mail has been open for a minute or so, it does not receive new messages. New messages ONLY arrive upon opening Mail. Attempting to quit at this point freezes Mail and requires a force quit.
2) Attempting to view/sort/search mailboxes fails after a minute or so of Mail being open. (i.e. When I am in mailbox #1 and I attempt a search or click on mailbox #2, Mail freezes and won't display a list of messages or the body of a message. Attempting to quit at this point freezes Mail and requires a force quit.
3) When I'm composing an outgoing message, if I've taken more than a minute or two, Mail won't send the message. I click on Send and nothing happens. The window showing my draft disappears, but the "Sent" Mailbox never changes to "Sending...", the message is not saved to Drafts and is never sent. Essentially it is lost (You can imagine how much fun this has been). Attempting to quit at this point freezes Mail and requires a force quit.
Any thoughts on what's happening here? On an unrelated(?) note, I've had the same issue others have discussed, wherein Safari is not retaining cookies. Safari has also been freezing my screen and mouse several times a day, necessitating a hard restart. Don't know if this is related; one problem at a time.

Anybody? Any thoughts? Maybe a starting point...?

Mail app won't send

its causing me much anger. any suggestions?

Most if not all internet service providers (ISPs) now block the use of SMTP servers that are outside of their network or not provided by the ISP on Port 25 which is the default or standard port for SMTP servers.
Some ISPs allow the use of an authenticated SMTP server only (such as the .Mac SMTP server) on Port 25 but some block its use regardless.
These restrictions are in place as part of an overall effort to prevent spam emanating from the ISP's domain.
.Mac's SMTP server and Gmail's SMTP server are what is called Password authenticated. I don't know if the SMTP server for your school's account is authenticated.
Do you not know who your internet service provider is which would be the ISP you use when connected to the internet at your apartment?
If you weren't having any problems before, sounds like all these different networks with different ISPs that you use to connect to the internet don't block the use of an authenticated SMTP server and if you send messages with all three email accounts when connected to the internet with different ISPs, the SMTP server for your school's account must be authenticated also.
Lets check the settings for .Mac's SMTP server. Go to Mail > Preferences > Accounts and under the Account Information tab for your .Mac account preferences at the SMTP server selection, select the Server Settings button below.
The settings should be as follows:
Outgoing Mail Server - or SMTP server: smtp.mac.com
Server Port: 587
Use Secure Sockets Layer (SSL): Can be selected or not selected.
Authentication (Type): Password
User Name: The portion of your .Mac email address in front of the @ sign only.
Password: The account's password - the same password used to check the account for new messages.

Mail app won't send mail to my .me or .mac account

My ISP is roadrunner in Rochester, NY. On my iMac, running Tiger, my wife, in her account, can send and recieve email just fine using her roadrunner mail account with the mail app. The problem is that wen she sends email to my .mac or .me account, it doesn't reach me. There are no error messages and the mail successfully shows up in her sent folder. In comparison, I have my roadrunner account set up so that it forwards all my mail to .me. If she sends me mail using my roadrunner address, it reaches me.
Does anyone have any idea why her account is failing at sending mail to .me or .mac but works with everything else?
