Intermittent issues with sending mail on Mac Mail but not Thunderbird

Some background: I have to use my ISP's SMTP server (AT&T) in order to send any mail out from my multiple email accounts. All emails are "validated" to use AT&T's SMTP server so there isn't any issue there. I cannot replicate this issue 100% of the time... it's about 20% of the time and has been experienced on both my Macs. When it does happen, outgoing email will either just hang (gear icon spins endlessly) or I get the SMTP server error message asking me to try another SMTP server (which I don't have).
What is odd, I recently downloaded Thunderbird using the exact same settings as Mac Mail. Whenever Mac Mail hangs, I try sending an email from Thunderbird and it works just fine. I have also tried sending email from my iPhone while in "airplane mode" and it works just fine.
I have performed connection doctor, keychain repair, deleted and reentered the SMTP info. So before I dump Mac Mail (which I'd rather not do) and go to Thunderbird, I would be curious if anyone has any suggestions?
Thx!

Now following another similar thread: http://discussions.apple.com/thread.jspa?threadID=2774396&start=0&tstart=0. Changed settings to MobileMe's IMAP default settings. Been working for 3-4 days. Hope it continues.

TS3899 Intermittent issue with sending emails from a blueyonder.co.uk email address.

Hi can anyone help? My iphone 4 has recently developed an intermittent issue sending emails from my 'blueyonder.co.uk email account. The emails get delivered to my outbox with a message 'cannot send mail, recipient was rejected by the server' When the emails are in my outbox there is no means to delete them there the only way to remove them is to remove the full email account and reset it up again.
I have tested the send functionality with my Gmail account and this seems to work ok!
I have spoken to Virgin Media my email provider and they have walked me through removing the account and resetting it up again but to no avail. They have suggested I contact Apple as there appears to be something wrong with the email application on my phone for this particular email account.
All incoming emails are being received as normal

Please help all surgestions greatlly reacived

When sending a message from Mountain Lion's Message program, you should be careful about the recipient's address. When you send a message to your dad, you should send it to his iPhone's phone number.
Also, on your Mac's Messages > Preferences > Accounts, you should be logged in under your Apple ID (which is hopefully different from your dad's).
Enjoy your Apple gear! Indeed, it does "just work".

Problems all of a sudden with sending files through MAC mail?

My .Mac email has acted up over the past week. I used to send documents smaller than 300k every day to whoever with no problems. Now, I'm lucky if they even go. A progress bar will tell me 8% done... 15% done... 21% done and then most of the time I'll get the message 'Could not be delivered... Try Again or Save for Later?'. Every now and then I'll get lucky and one will send, but it's become rare. Even when it does go it takes FOREVER. 5 minutes or more. They used to take 30 seconds... if that. This is a problem on three different G5's with Mail version 1.3.11 (v622/623). I use a high-speed cable connection to the internet, so it's plug and play for me basically. I even created an account with Comcast mail just to test the documents there and they shoot through with no problems (but that defeats the purpose of using my business email address on .MAC).
Any suggestions?

Are you saving Sent messages on the server with your .Mac account on all computers?
No.
Are you using Port 25 to send messages with the .Mac SMTP server in Mail on all Macs?
Yes.
If so, try changing the Server Port from 25 to 587. Go to Mail > Preferences > Accounts and under the Account Information tab for the account preferences at the SMTP server selection, select the Server Settings button below. At the Server Port:, enter 587 in place of 25 in the space provided and when finished, select OK to save the changed setting.
Tried that with the same result. I'm stumped. Could there be something wrong with my router you think? Thanks for the help!

Seems like alot of people are having the same issues with being able to receive email but not send emails. Like others, I have tried re-booting, switching off, deleting account, reinstalling account but to still no avail! Does anyone else have any ideas?

Hi there - I have rebooted and turned off ipad and deleted my yahoo account and reloaded it but I still cant send messages, any other suggestions? Thanks.

Me too,
I can logon to Yahoo directly with my wife's iPad. I can then send an email to my iMac. What I cannot do is send an email directly from her iPad to me - so I consider the problem is with iOS 7.0.3. All i get is a long 'sending' session that ends with "incorrect username or Password", but that cannot be right. I have deleted and re-created the account on the iPad - cleared Safari's history and cookies. Nothing changes. It seems to be very widespread this problem and as yet nothing coming from Yahoo or Apple. This is similar to the Windows' users experiences. Pity.

Hi, Using MAC OSX 10.6.8 and have intermittent issues with receiving new emails - sending is OK. I've tried the workarounds (take offline & take online), quitting mail etc - no luck. Any suggestions?

Hi, I'm using MAC OSX 10.6.8 and have intermittent issues with receiving new emails - sending is OK. I've tried the workarounds (take offline & take online), quitting mail etc - no luck. Have cleared space, checked Window - Doctor and server has green light. Mail Activity shows 47 emails waiting to download, iPad and iPhone download them all OK - no extra big files stopping the download either. In the past, quitting mail has worked, but not today... Any suggestions?

Sending mail with attachment fails on MAC Mail and WRP400.

Sending mail with attachment fails on MAC Mail and WRP400.
We have hundreds of WRP400 connected with Mac (Machintosh) computers. No special configurations are applied (no virtual server or DMZ). Web navigation, P2P programs and sending mail without attachment work right.
The problem is the impossibility to send mails with medium or big size files attachment from MAC Mail.
If we use Windows PCs or a different linksys routers (eg. WRT54G) the problem not happens.
We have upgraded WRP400 firmware version from 1.00.06 to 2.00.05 but the result is the same. Sending mail with attachment using Mac fails.
We tried to configure WRP400 with DMZ to a particular MAC. We tried to configure Virtual server on tcp 25 port of a MAC. The result is always the same.
This is a WRP400 bug? Windows PCs work right. MAC and MAC mail works right with other linksys router.
We need help. Thanks.

The problem was fixed since beta firmware 2.00.11.
I think that this issue was caused from a bug that decrease upload bitrate of WRP400 after some days of activity.
See more details on Cisco forum under title "WRP400 stops responding after browsing certain websites".
Thanks.

Having issues sending mail through mac mail on my imac .Have 4 accounts

I am having issues sending emails through mac mail. Have 4 accounts and they are all having same issues
Can receive mail ok
have tired rebuilding the mail box but no improvment.
i need to shut down system and restart to be able to send mail.

I tried something similar by adding a new mail account doing the apple id etc but it worked in that it would look for mail but no mail would come even though mail still goes to my phone I was loath to delete my original account just in case the new one did not work as well. So I guess I am a little stuck now.. I hope you can help me to sort it out.
Thanks

Spent two hours on the phone today with BT. They escaleted the problem to a specialist support desk, which we then had to agree to paying a £30 charge if they were able to fix the problem as they say that it is a problem with mac mail. (Which it isn't because it works fine using a different broadband connection, and we have three laptops in the house all with same problem, using outlook as well as mail).
All three laptops have been working with out fault for the last four years and just before christmas they all stopped being able to send emails using hotmail. Obviously BT have changed something somewhere along the line.
The Specialist just changed our outgoing mail server to use BTs instead. (I have been using a different SMTP server anyway as a temporary fix since christmas) Whilst we are able to send emails, we are still unable to connect to hotmails SMTP server. Still had to pay the £30 though. As far as they are concerned that still counts as a fix. Another "solution" they gave me was to change the DNS address in system preferences- Not Ideal as everytime you connect your laptop to a new network you will have to reset them.An absolute joke.
Their direct number is 08000 321 118 if you need them to talk you through it. Best to have your bank card to hand.
Livid.

Cannot send mail from mac mail or Entourage

Hi guys,
Wondered if anyone out there can shed some light on this little problem.
I use Entourage for my emails & all was working fine until yesterday. I can receive mail from all and sundry but I can't send anything. I subscribe to ntlworld internet service and if log onto my email through their webmail, then it's fine. I've tried sending mail from mac mail and I get the same problem. I've been onto microsoft support & gone through all the troubleshooting with Entourage. The Entourage techy suggested it was my internet provider blocking my emails as they think I'm a spammer?? I phoned ntl & they insist it's nothing to do with them as I can send/receive from the website. (If I send an email with the address @ntlworld it's fine, but any other address i.e. all my clients/mates etc just stays in my outbox.
Nothing on any of my settings has changed so I'm at a loss what to do next.
Any suggestions greatly appreciated.
Thanks, Mel

it may be that your server (internet provider) has just started blocking outgoing mails not authenticated by them.
Go to your account set up...
and fill in the following details.
SMTP SERVER: smtp.mac.com
then click on advanced sending otions...
click on override default SMTP port... type 587
click on SMTP servber requires authentication...
use same setting as receiving mail server.
try this...

I have an issue with the address browser in mail in Yosemite

I am using IOS 10.10.1 now on an iMac and have discovered an issue with the address browser in mail.
Previously in my pending to send email toolbar there was a contacts icon which I clicked on to display my contacts list. I could hold down the Command button and select as many contacts I wanted (often up to 100), then select the field to send (to, ccc, bcc) and the contact would appear.
Now, I have to click the + sign at the end of the field line, and select recipients one at a time. Not only that, but I have to click twice to get to the email address, once on the name and then the email address drops down under the name and then I click on the email address. When I do that the drop down box disappears and the recipient's email address goes to the field. I have tried all combinations of buttons to be able to choose multiple addresses but haven't found the right one yet.
An Apple Support guy told me to open my regular Address book, and hold down the command button to choose multiple recipients then drag them to the field on my already opened send email.
This is one way around the issue (which wasn't an issue in Mavericks) but where some recipients have two or more email addresses listed in my contacts it means I have to manually go through the finished list on my emails to make sure the most desired one was selected. What a pain.
Also, previously, where I was sending out many emails and wanted to stop say half way down my list, and send, I could come back to that list for the next email and see where I'd got up to.
I don't want to make groups because my recipients vary depending on what I am sending so my lists change constantly.
Any suggestions?
Last point...who archives? On my regular email page I now have the Archive icon to the left of my Delete icon which I would prefer was to the left, first in the line as this is the icon I use mostly. With Folders, my Sent and Trash lists, who needs to archive?
Cheers,

I can help you only with the placement of the icon placement -- if you right-mouse click on the toolbar, then select Customize Toolbar, you can move an icon to where you want it to be.

I have an iMac, and have a Verizon DSL account. Recently, my Mac Mail keeps requesting the passwords on my account every few minutes, and will not allow me to send messages using Mac Mail. I cannot edit the outgoing server; how can I send emails?

I have an iMac, and have a Verizon DSL account (3 email addresses). Recently, my Mac Mail keeps requesting the passwords on my accounts every few minutes, and will not allow me to send messages using Mac Mail (the message says that the outgoing server was rejected. I cannot edit the outgoing server, and the keychain will not save my passwords (the ports are valid). How can I change the outgoing server to send emails, and how can I avoid having Mail request my passwords every 2 minutes? Verizon, as usual, will not provide support to iMacs.

Is there an email saved in your drafts or outbox folder? I suspect that Mail is continually trying to send it, and each time Google is rejecting the email message.
You can open the message and then delete it from your Outbox folder. Then try removing all @gmail email addresses from it and seeing whether you can send to the other folks. I suspect that will work.
With email, if an SMTP server *can* verify email addresses, sometimes it will and it will refuse to send messages. If a message has to be relayed across servers, no verification is done, and you'll get a bounce if an email address is bad.

Sending pdfs from Mac Mail to Outlook

I have users that are sending pdfs from mac mail to outlook and the attachements are not going through. All you see is the paperclip and nothing else. This has just started happening. I am telling the users to send emails as plain text with windows friendly attachement as well as to put the attachment in the email. Anyone have any idea how to fix this. There are some unhappy users.
Thank you for the help
Jeff

Outlook for Mac has no option to import from Apple's Mail application. The best suggestion I can offer is that you use an IMAP account to transfer your messages.
Get a free Gmail IMAP account from Google and connect to the account in Mail. Drag your messages into the account to copy them to the server.
Connect to the same account in Outlook and copy your messages from the server to folders under On My Computer.
Another option is to get a third party tool that are available online.
One tool that I am familiar with is Apple Mail Export
Or you can find more on
google or
yahoo for more results
Hope this helps!

TS3276 sending emails from mac mail?

not possible to send email from mac mail since hotmail changed to outlook?

The logo is an attachment. Anything in an email message that is not text must be sent as an attachment in order to be compliant with email protocols. But many modern email programs will automatically display the contents of some attachments. Apple Mail will display JPEGs and single-page PDFs. Presumably your correspondents are using an application that displays JPEGs but not PDFs.
Some email programs expect attachments to come at the end of the message, not intermixed with the other contents of the message. Such an app may treat everything after the first attachment as attachments. That might cause the different behavior when additional attachments are included before the attachment in your signature.
