Cannot send emails from mac email address

Over the past 24hrs I am unable to send emails from my ibook and sporadically from my iphone. Please advice what the settings should be for SMTP and port. I think this might be the problem but I am unsure. I have a mac email address. I can send emails from my icloud account. Any help would be appreciated. Thanks

Wow, after research I can't believe what a problem BT is!???
This post by vanessa seems to have gelped many that could not send...
Just set up my macmail with the help of the BT guys after a year of struggling! Hopefully this could work for others for whom the emails will receive but NOT send....
Set up your 3rd party domain names via the mail relay system and confirmed via BT. Then try these settings.....
In your @btconnect.com email set its up using these:
incoming mail server: pop3.btconnect.com
username: the bt email
password: the bt email password you supplied
outgoing mail: we'll come to this!
on the drop down box next to Outgong mail server (SMTP) select 'edit SMTP server list'
press '+' button and add these details....
In the Account information tab:
Description: mail.btconnect.com
Server Name: mail.btconnect.com
In the advanced tab:
Select 'Use default ports'
Authentication: Password
username: the bt email
password: the bt email password you supplied
NOW The next bit, the 'second' server....
press '+' fro a new server add these details....
In the Account information tab:
Description: second server (or any name you want)
Server Name: mail.btconnect.com
In the advanced tab:
Select 'Use default ports'
Authentication: NONE!
Now on all your email addresses back in the accounts section, set the SMTP server to 'second server' (or whater you hae called it) NOT mail.btconnect.com and select Use only this server.

CANNOT SEND MAIL FROM .MAC SMTP ACCOUNT

Hello everyone--
I can receive mail from my .mac account and have done extensive troubleshooting including:
1. Changing ports from 25 to 587
2. Deleting and re-installing mailbox
3. Reading a hosts of topics
4. I have the serving settings with SSL unchecked
...but this still giving me the same trouble. I cannot send out because my email address keeps getting rejected.
Any suggestions? Thanks!

Are you also accessing an email account and SMTP server in Mail that is provided by your ISP used for connecting to the internet?
If so, can you send mail with this account and SMTP server?
If the answer is yes to both questions, select/use your ISP's SMTP server to send mail with your .Mac account which is invisible to all recipients.
Most, if not all ISPs now block the use of SMTP servers outside of their network on Port 25. Some ISPs allow the use of an authenticated SMTP server only (such as the .Mac SMTP server) that is outside of their network on Port 25 but some block its use regardless.
Changing the Port for the SMTP server that is outside of the ISP's network from 25 to 587 usually resolves it but sometimes not depending on the ISP's restriction.
Have you contacted your ISP regarding their restrictions and/or requirements when using an SMTP server that is outside of their network or not provided by them?
Using your ISP's SMTP server to send mail with your .Mac account should work and it may be required regardless.

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.

Can't send email from .Mac alias address

I have been using an email alias with a .mac account ever since aliases were enabled.
I am able to get mail sent to that address, but there is no way I can send mail from it. Its not an option in Mail apps "From" list. Even when I reply to an email send to the alias, when I reply to it, the From address defaults to my main .mac email address.
When I go to icloud.com, I see the correct alias is listed there.
I did a search here but didnt find an answer. Any help would be appreciated, thanks.

Try deleting the email account in Mail's Accounts preference pane
and then add it back. That will automatically enter the correct server addresses.

Cannot send mail from .mac account in Entourage

I am a new mac user so my troubleshooting skills are very weak. Until about one week ago, i was able to send mail from both my hotmail account and my .mac account. Now, i get this error (just on my .mac account):
An operation on the server timed out. The server may be down, overloaded, or there may be too much net traffic.
i read through much of the support articles, but did not find my specific error. can anyone help??
thank you

Cannot send mail from yahoo email account.

I recently developed a problem with sending messages through the ipad mail app. The primary server is Yahoo! SMTP Server with the SSL use on and port 465 open. However the hostname isn't specific. Just says "Yahoo! SMTP Server". I can't access it to change it so I made a second one below it as outbound.att.net because on AT&T website they changed the smtp settings. The outgoing mail port # is still the same...465 and I read online to change to 25 if the account is a business yahoo email but mine isn't and the ipad froze on me while attempt to verify. Can someone help me sort this out? I only have this issue when I'm on the actual data plan and I'm on the go.

Not sure about yahoo, but for gmail, I done the following:
Set up using Exchange on iPhone, it'll keep prompting for password. On PC use captcha option, log in to gmail account from PC after completingg captcha option, enter password on iPhone.
See how that goes for gmail, let us know.
Hopefully someone will have fix for yahoo.

Cannot send message (from mac mail) using the server iCloud

My Mac Mail send stopped working during a large number of mail sends yesterday.Could that be an issue? If so, what to do?
Message further reads - The sender address [email protected] was rejected by the server smtp.mail.me.com.
I deleted the account and set it up again, but still can't get the mail out. Same messages
If I go on to iCloud, mail send is working fine.
Can anyone see anything wrong or suggest what to do?
I've deleted the user name below for the screenshot.
Thanks in anticipation.

There is no user name entered in your SMTP (advanced) preferences.

thank you

I have been having the same problems for the last two days now. It won't let me send, but it will let me save it to my drafts folder. I even tried opening the e-mail form my iPhone 5 and it won't let me send it there either. The last two times i ended up copying the contents from my failed e-mail on my phone and pasting that into a new e-mail and that works. I normally use the icloud web app to reply to e-mails when i'm at work (using win 7) and it is very frustrating.

You can try deleting the account on your iphone and setting it up again.

Send from .mac email

I would like to send from my .mac email address which I have had since the 90's or whenever they issued them. I have run into a roadblock because I need to send an email from .mac to access an account that was set up with that account. Plus, I never likes .me! I thought I did the migration correctly, but .mac is nowhere to be found. It is still my username for itunes, icloud, etc!

hi Skip,
I don't think that Apple will fix it "soon" but in the meantime and with all the experience you have gained in reading the Discussions forums, it will be a breeze for you to manually fix those on the fly !
I installed from scratch and didn't have a single issue, probably the easiest upgrade of Mac OS for me. I updated my wife's iMac and I didn't encountered the problem you faced. Difficult to predict what the situation will be on your wife laptop but if there is an issue with the smtp server: you know what to do !
Do not hesitate to come back and ask any question(s) you may have if you decide to upgrade your wife laptop.
Bye for now,
/Phil

Sending Group email from .mac

Can you send gorup email from .mac address book?

If you mean using the .Mac mail web interface, the answer is no. The .Mac web interface address book does not support the groups defined in OS X's Address book.

Hi, i am having trouble with my mac mail account, i cannot send or receive any emails because of the server connection problems. Message says it could not be connected to SMTP server. Thanks in advance for your help.

Hello Sue,
I have an iPad 3, iPad Mini and iPhone 5S and they are all sluggish on capitalisation using shift keys. I hope that Apple will solve the problem because it is driving me crazy.
I find using a Microsoft Surface and Windows 8 phone, which I also have, work as well as all the ios devices before the ios 7 upgrade.
It has something to do with the length of time that you need to hold the shift key down. The shift key needs to be held longer than the letter key for the capitalisation to work. For some reason, this is a major change in the way we have learnt to touch type on computers. I am having to relearn how to type!

When I send an email from Mac Mail, why does Mail go to the background and the Finder comes to the front? I want it to stay in Mail.

Did you check your user name and password in Settings>Mail,Contacts,Calendars...tap your email account, tap SMTP, then tap the primary server name. Make sure the settings there are correct.

I am using Mail 5.3 with two separate gmail addresses. One is personal the other is business. When I send emails from the business address, any auto-replies I get COME TO THE PERSONAL INBOX. I imagine that this is a setting? Please help!

I am using Mail 5.3 with two separate gmail addresses.
One is personal the other is business.
When I send emails from the BUSINESS address, any auto-replies/out of office notices I get come to my PERSONAL INBOX.

Edit the SMTP server list. Add a new one for the business account. Put the correct password and information for it. Give it a description so you will know which server is which. Mke sure the correct server is highlighted in the account selected and check the box to use only that server for that account. Do that for the other account also.
