Mail "Cannot send message" but Thurnderbird can

Mail is giving an error message "Cannot send message using server" - on all my servers including dot mac..but Thunderbird can, with no probs...
This happpened a couple of months ago and reentering all the settings did not work so I used Thunderbird with no probs for a while..then I archived my emails in Mail and trashed all the accounts settings.
Mail worked just fine for a few weeks..then the same problem
any ideas?

Mail worked fine on a wireless connection this morning
Who is the internet service provider associated with this wireless connection?
But now we are back to no sending (the message btw is
"cannot send message using this server") on the ethernet connection
Is the internet service provider for the ethernet connection different from the ISP associated with the wireless connection?
Which server port are you using for .Mac's authenticated SMTP server with Mail and with Thunderbird?
Are any of the other SMTP servers not provided by the ISP associated with the wireless connection or with the ethernet connection authenticated and if so or regardless, which server port are you using for the SMTP servers not provided by either ISP or if the same ISP with both connection with Mail and Thunderbird?

OSX Mail - Cannot send message using the server ....

Hi there,
Mac Pro with OSX 10.6.
*Can receive mail, but can no longer send email* using the program Mail.
Been getting the popup "Cannot send message using the server [shawmail.vc.shawcable.net] for the past 3 days. I hadn't changed anything about my computer, and have had the Mac for 2+ years. So this just started doing it on it's own.
I had a technical support guy from my service provider even interface with my computer, where he could see my desktop right over the internet, and he couldn't get it fixed either.
I googled this problem, and found solutions like:
1. Uncheck "Use SSL" (Done that, and it was never checked "on" to begin with)
2. Make sure Authentication is set to none, with no password (done that, and it wasn't set with a password to begin with)
3. Delete [user]/Library/Preferences/com.apple.mail.plist (done that, didn't do anything)
4. We even totally deleted my account, and started a new fresh one. Didn't work
The tech support guy did show me a way to email online, using the same email account. That worked, but it's a hassle to go onto a web-based email program -- it's not my preference. So, with great certainty, it's not my service provider, because I was able to send emails on this web-based email program using my email account.
So there, I'm stumped.
Hopefully someone can help. What's bizarre is that googling this problem, I have found many other people that say it happens arbitrarily, out of nowhere.

I can't believe how ridiculous this issue is. i have been searching for days for a solution to this. i have tried EVERY recommendation on these forums and nothing works. It appears that this issue dates back to TIGER. I had this problem back in January and just bagged figuring it had something to do with iweb. I bought a new html program and was able to send out my newsletter last month no problem. Suddenly, one month later- here i am again, unable to send out my newsletter with no help from Apple or verizon, or these forims, or anyone else. To think that a company that I have stood behind and loved so much can't be be bothered fixing such a simple issue that has been going on now through 5 OS's (I am using Lion but I had the issue using leopard as well) is a disgrace.

Yahoo Mail - "Cannot Send Message"

Hello,
I am having issues with Yahoo mail and sending messages. It seems to happen specifically while trying to send emails with attachments. I receive an error that says "Error sending message" and alludes to a connection problem but I don't see any detailed error information with it.
The MacBook connects either directly to a Ethernet cable or wireless to a NetGear WGR602.
I don't know much about Safari but are there are settings I can modify to see if the issue can be resolved? The user says that she does not have this problem at home but only when she is on this network.
Has anyone encountered this and have any tips I can try to resolve it? When I get some time to sit and work on the laptop I will check to see what versions all of the software is at. Right now I have only had a few minutes to sit at the MacBook and observe the errors.
Thanks in advance!

Short of installing Firefox or moving directly to Mac Mail, is there anything I can look to do either with Safari or the Yahoo interface itself?
Not really. If the user has a free Yahoo! Mail account, they can't use Mail to send/receive anyway; they'd have to pay $20 a year for a Yahoo! Mail Plus account for that privilege.
Yahoo! has never made any real effort to be standards-compliant, much less compatibile with Macintosh, which is why some features work only when using Firefox on a Mac (because Firefox is the second-most popular browser for Windoze). The only other thing the user could do is use the Yahoo! Help pages for Yahoo! Mail and send them an email using their web form about their problem and see if they can address the issue on their end, since it is their problem. He/She should make it crystal-clear that they are using Safari for Mac OS X, and if they get a boilerplate reply about IE, reply to that and ask for a supervisor.
They could also try using the Develop menu in Safari to select a different User Agent in the hope that spoofing an IE browser will make it work, but there's no guarantee with that. They could just resign themselves to using Firefox when using Yahoo! Mail, or they could also try switching to the "Classic" Yahoo! Mail interface, which will have some limitations in features, but it may also avoid this problem when sending some email.

I am on a Norwegian cargo ship off the coast of Norway. It has Wi-Fi, but I cannot send emails using my iPad. I understand that Verizon has had big problems recently. I cannot phone Verizon for advice, and if the problem is Verizon's fault, I do not want to change my settings. Can anyone advise me how to fix the problem? Very frustrating and I have not been able to reach technical support using my Safari browser.
Sincerely, W. E. Howard

Not sure where the previous poster's setting come from but certainly are different to what I use also I have to ssume you are using some form of mail client as using web mail should be no different wherver you are in the world.
Incoming server - incoming.verizon.net
outgoing server - outgoing.verizon.net
login information - your userid and password for your email account
More settings
outgoing server - outgoing server (smtp) check requires authentication
use same settings as incoming mail server for security
Advanced - incoming server (pop3) port 110
outgoing server (smtp) port 587
I would guess that your issue is probably the outgoing server port. If you have it set to 25 it will work when you are connected to a verizon network otherwise the mail will get rejected for reason relaying.
EDIT
Ah I see where previous poster got his setting, they are on the page he referenced, interesting that it mentions DSL on there. I am a FIOS user. Can't believe there are any difference in mail setting between FIOS and DSL but maybe,
I took my mail setting out of my Outlook email client properties and they have been working fine for years.
As to changing setting you need to bear in mind. Settings that are used on devices that are not attached to Verizon's network WILL work when the device ias attached to the VZ network.
The reverse is not necessarily true.
The settings mentioned by you are the very old settings. They were changed at least a couple years ago. The latest ones are as mentioned by Jumpin68ny for VERIZON email (DSL AND FIOS included) where a third party such as Yahoo is not used.
Mail server settings
Incoming mail server (POP3): pop.verizon.net
Incoming Server Port Numbers: 995
Outgoing mail server (SMTP): smtp.verizon.net
Outgoing Server Port Numbers: 465 Why is this important?
Your Verizon Online user name
Your Verizon Online password
Make sure "This server requires a secure connection (SSL)" is checked.
Also make sure when using these SSL servers that the password is normal (in the clear).

My Gmail has been working fine until today. Now I cannot send messages. I can receive them fine.

I have a brand new computer, using Yosemite. My mail program has been working fine for several days, but suddenly this afternoon it is unable to send mail. I can receive mail just fine. I can send mail from a different email account. How can I fix this?

TS2755 I cannot send iMessages but I can receive them. Even if I have perfect signal I can't send an iMessage, and I have iMessage on in my settings.

I don't understand what is happening! This worked fine before I downloaded IOS7.

Try this:
1) Settings
2) General
3) Reset
4) Reset Network Settings
This will reestablish the link for the cellular connection and the cellular data as well as the saved WiFi connections will be reset.
Also Check this:
1) Settings
2) Messaging
3) Ensure iMessage is turned on (sometimes it will turn itself off for some reason)
4) Press on Send & Receive
5) Ensure that all emails you want to be reached at as well as your phone number are listed there
Remember that iMessage requires a data connection so with out either cellular data or WiFi it will not work.

Keep getting 'Cannot send message using server...' message - Why!??

Hi there,
Every time I launch Mail, the first time I try to send a message I get the same window, warning me that Mail 'Cannot send message using the server...'.
It's annoying, because this is the only server I have, and it does work. I just have to hit the 'Use Selected Server' button, and it works.
But next time I launch Mail, I have to go through the same tired routine.
Does anyone have any suggestions as to what I might do to solve this problem?
thanks so much,
Malcolm

Hi Malcolm.
It isn’t clear whether you’ve always had this problem in Mail, or it started to happen as a result of some changes you made, or what...
Is this outgoing server associated with a mail account provided by your ISP or something else?
Doesn’t the error message give any additional information as to what could be the cause of the problem? What does Window > Connection Doctor say?
Go to Apple Menu > System Preferences > Network, choose Network Port Configurations from the Show popup menu, and make sure that the configuration used to connect to Internet appears at the top of the list. Try also turning OFF all the network port configurations except the one needed to connect to Internet and see whether that helps — if it doesn’t, turn ON again the ones you want enabled.
Also, try using a different method to connect to Internet, if possible, or connecting the computer to Internet as directly as possible, i.e. bypassing any routers that might be present, using an ethernet cable instead of wireless, etc.
Mail keeps information about outgoing (SMTP) servers in a separate list independently of the mail accounts themselves. The account settings just associate one of the available outgoing servers with each account. Orphaned or dangling outgoing server entries (i.e. not associated with any account) sometimes cause weird sending problems.
Go to Preferences > Accounts > Account Information > Outgoing Mail Server (SMTP), choose Edit Server List from the popup menu, and delete any servers that shouldn’t be there. The Edit Server List panel shows the account each outgoing server is associated with.

HT1277 I can recieve emails but I can't send them out. The blue bar at the bottom left of the Mail page gets half way across and then the pop-up "Cannot send message using the server" comes up? What do I do?

I have my Yahoo Mail "poped" over to Apple Mail. I can recieve emails but I can't send them out. The blue bar at the bottom left of the Mail page gets half way across and then the pop-up "Cannot send message using the server" comes up? What do I do?

Your outgoing mail server is different than your incoming server. Usually the outgoing mail server will have smtp in it. I noticed yours said "cannot send message using the server mail.wavecable.com". That sounds like an incoming mail server. Try setting your outgoing mail server to smtp.wavecable.com
I hope that helps.

TS3274 how come all of a sudden, I cannot send/receive messages, but I can receive e-mails in my Ipad?

HOW COME I CANNOT /SEND RECEIVE MESSAGES, BUT I CAN RECEIVE EMAIL?

Sending and receiving messages has absolutely no relation at all to sending and receiving email.
Your iPad is not a cellular telephone. It cannot send or receive SMS text messages. It can only send or receive iMessages, which are messages to/from other Apple devices (only) on a WiFi or a cellular network that supports iMessage.

Suddenly cannot send messages from ipad. Can send from iPhone and they show up on messages but when sending from ipad a they say not delivered

Just upgraded to Yosemite 10.10.2 on my iMac 24 inch and now my Suddenlink POP email account won't accept messages. The message says unable to receive Mail and the warning says: Mail cannot send your password securely to the server. You can remove th

Yesterday I uploaded Yosemite 10.10.2 thinking it was fixed by now. In Mail, my POP account gets this error message: Mail cannot send your password securely to the server. You can remove this restriction in the Accounts preferences by setting “Allow insecure authentication”, which could put your password at risk.
My provider says it's an Apple issue. The gmail accounts are logging in fine. Any help? Something simple?
Thanks anyone.

Thanks Csound1. That did work and Mail was able to connect to the internet. Green light status. Is it because of my provider that I may never have had secure connections? Is that an Apple thing or do PCs have the same issues? Appreciate your help. I'll research insecure connections as I am ignorant of the consequences.

I'm not concerned about sending to the long address list. I just can't get the email and window that says "cannot send emai using the server..." to go away. The default must be "retry", because although I cannot see the choices at the bottom of the window if I hit return it trys again... and then of course comes back with the very long pop up window that I cannot see the bottom of so I can tell it to quit trying...
