Why won't my mail send using apple mail client?

I have OSX 10.7.5 on my IMAC. I had not made any changes to anything and as of Tuesday my emails will not send while using apples mail client (mac mail???). If I log in to ATT.net everything works fine. ATT says its the mail client and Apple says its not them (it's an att problem). Three hours and forty minutes later still no resolution. Both tried hard but no repair.


Any suggestions????


THANKS!

iMac (21.5-inch Mid 2011), Mac OS X (10.7.4)

Thanks LD


I have gone over most of those tips/suggestions with no result. I will complete every item tonight. I had an Apple "advance tech" helping me last night for an hour. She tried many tests and trouble shoot ideas still nothing. I just do not understand how it can work fine for 8 months and all of the sudden stop.


Five people (att & Apple) were assisting me and put forth a very good effort. Att finally refered me to thier fee based techs. The advanced tech with Apple is hanging in there.


I'll try again tonight.

So you've had five folks on this including Apple? Um, OK. Chances of success here in the forums will be low, and — without some indication of what's been tried — we're going to be duplicating tests.


Definitely follow the troubleshooting information that Linc Davis's pointed to.


On no evidence, I'd wonder if there's an issue with the AT&T mail servers, or with reaching the AT&T servers from your local network. In particular, stay off of TCP port 25 for sending mail. That's usually tested with telnet or openssl s_client, depending on what's going on, though Connection Doctor should pick that up.


There's also been an apparent account corruption seen very occasionally, so if nobody's already tried this, entirely remove the account entry, and re-add it. This entails removing both the POP/IMAP connection configuration for receiving mail from the server into Mail.app, and also removing the SMTP/ESMTP connection configuration for sending mail from Mail.app to the server. Then re-add the connection.

Hi there,


I finally got my mail to work! I tried everything under the sun. What finally worked:


Under the Inbox icon-There is an icon for your mail account "xxxx". Control click that icon and select take "xxxxx" online. Next I control clicked the same mailbox icon and selected get new mail from "xxxxx"


On one account it worked the first time, the second account I had to retry a couple of times before it finally connected.


Since then, it lost connection again. For whatever reason, this procedure seemed to work a second time.


Can not figure out why this seemed to work, when you can do basically the same thing in two other places with no success.


Hope it works for you!

Are you using WiFi networking, and are you in a fairly built-up area such as a townhouse or apartment building or similar? In particular, is it possible that your WiFi network is flaky? If so, it's common for Mail.app to toss (among other errors) password error dialogs and other connectivity errors. If you have the option, move your WiFi to the less-crowded 5 GHz band, or (for testing purposes) use a wired network connection.

So far this tip is working for me:

Using OX 10.6, Mail 4.5. None of the solutions worked for me so went to att.com and plowed through a long collection of possible solutions, many wanting you to buy their fee-based support: AT&T ConnecTech. I found one that mentioned Authentication Required. So went back to Mail Preferences:Accounts:Account Information and for Outgoing Mail Sever (SMTP) clicked on Edit SMTP Server List. Clicked on Authentication and selected Password. I entered my User Name (full email address) and Password, clicked OK and all is now working.

LD, The condensed version is, all server settings were correct. "connection doctor" results for inbound are good and outbound says "Trying to log on to this SMTP account failed. Verify username and password are correct". They are correct and had been verified several times. Then I changed my password for testing and still same message.

LD, I believe the techs worked through all of the trouble shooting tips from your link and I've done some myself. The Apple mail client will not link up with the SMTP server. Not even sure if I'm explaining that correctly but emails still will not send using the mac mail.


Elaine, not resolved. Tried your suggestion with tech's and on my own, still not working.


Thanks to all!

Bob


I'll be here pulling my hair out! 😠

Hello NB,


I am facing the same issue. So far I have figured that if I connect to my ISP (Internet service provider) I have the same issue and I tried all the ways possible to solve this but cant find a solution.


If I use an unsecured wifi around my apartment, instantly my mail starts working. But the the problem is the wifi it catches is too slow and I cannot send my emails.


So the problem lies with the internet connection and I am sure there must be some firewall issue. Except my mail everything works flawlessly.


Please suggest me a solution!!
