I've been trying to fix outgoing mail from my domain name email since Christmas. I spoke to the domain host today and they suggested contacting my ISP Btinternet and get them to allow Btinternet smtp to handle my outgoing mail. I got on to BT and had really good help with this - they assigned my domain email address to Btinternet and then helped me set up my domain email to send through this. At last it works!! And it still appears to the receiver that they have received it from my domain email address.
The domain email host said they have had a number of reports of mac mail not working properly - particularly through BT as the isp.
This has happened to me a few times and it is an apple mail problem.
A combination of the following HAS WORKED for me
1) Delete and reset the icloud account/ password
2) Go to window, connection doctor - this sometimes works
3) If still a problem, go into the set up instuctions for your email account provider in my case gmail and eircom and follow the setup for incoming and outgoing mail. Apply these settings in Mail, Window, Connection doctor accounts or by double clicking on the account in connection doctor status screen. (follow settings instructions for port and SSL enabled/disabled etc) e.g. gmail settings below - you may have to re input your gmail password. (These settings are worth copying and pasting into a document for reference in case this happens again which it has in my case).
Incoming Mail (IMAP) Server - Requires SSL
Outgoing Mail (SMTP) Server - Requires TLS
Port: 465 or 587
Requires SSL: Yes
Requires authentication: Yes
Use same settings as incoming mail server
Full Name or Display Name: [your name]
Account Name or User Name: your full Gmail address (firstname.lastname@example.org). Google Apps users, please enter username@your_domain.com
Email address: your full Gmail address (email@example.com) Google Apps users, please enter username@your_domain.com
Password: your Gmail password
I suspect it's a case of needing to reset the mail accounts - the apple system seems to get stuck with an incorrect setting and by rejigging it it works again.
Total pain, apple problem - apple please fix!!
I have been to the Genius Bar, called my service provider, tried things suggested here and the inability to send continues, although sporadically. The corruption idea seems valid because sometimes if I close mail for a while and then reopen, whatever is sitting in the outbox (with the little doohickey spinning around) will happily zoom off. I think Apple really needs to take a look at this. There have been too many complaints over too long a time.
I've had outgoing mail sitting in the outbox for a while. The error message makes it seem that the username/password combination is not working and I know it's correct. I searched on the google support site using this query: "mail username and password not working" See this entry in the google product forums for gmail titled "Gmail username and password not working with Apple Mail IMAP"Hi everyone,
Not sure if this will help but fixed my outgoing smtp not working.
I ran the connection wizard which showed that of my two gmail accounts my primary one was connecting by IMAP, but not SMTP (red dot). I double clicked the bit with the red dot and it took me to my account settings where I could see that the account password wasn't filled in. Filled it in and it now works fine. Not sure why it did this as I presumed it was sorted automatically when I had re-setup the account.
Probably not everyones problem, but just in case...
I have worked for 8 months on Thunderbird mail under ubuntu but now got a new macbook pro retina to see this problem IS STILL THERE AFTER ALL THIS YEARS.
YEs, I remember having this problem on my older macs once in a couple of days. This is now March 2013 and Apple Mail is still having problems sending smtp mail ?
Are you kidding me ????
WHAT IS THIS ? BUGFIX THIS ONCE AND FOR ALL APPLE, THANK YOU.
Having same problem since latest update to OS 10.8.3 email won't go out and tells me the settings wrong, tried everything, right through to changing DNS numbers with the guidance of Apple after hours oon the telephone, they managed to resolve the outgoing problem by causing me to losing my incoming mail, see my other mail.
Still not resolved, basically we are all idiots in there eyes and can't set anything up correctly!
I have been having the same problem across all my accounts on my mac pro for about 6 months. It says can't connect to SMTP on all outgoing servers in connection doctor, have been searching for solutions on and off ever since with no avail. Wasted whole weekends on this!
From what I can gether it's a problem with Mail on Mountain Lion, as I use the exact same settings on my mac book running Lion and everythings fine, as well as on my iPhone. My girlfriend recently got a mac book pro with ML already installed but she never used mac mail, asked her to try it and the same thing is happening with hers too... ON A BRAND NEW MAC BOOK!
It's getting a bit ridiculous now, need an update soon... I would suggest calling themto complain but then we would no doubt be charged for the privalege.
