Can't send out mail on my POP

I am having a similar problem, but not with a .MAC account. We recently had to reinstall our operating sys. and now cannot send email with our POP. Everything else works fine and we can send it through the verizon website, just not the mail link. Error message reads the server does not recognize our address. Checked with Verizon and all settings are correct. Any ideas? I even tried the port 587.

Sometimes an ISP provider blocks one of your incoming
Mail ports and "won't notify you". ( Why? probably it's their protection software )
In my case Comcast blocked my Port 25 and my Outgoing kept bouncing.
Incoming was fine.
Make sure when you change your Port to 587,
You also check "ON" the Secure Sockets Layer box right underneath,
Then change Authentication: to Password
Then enter your name and password
and click OK.
The reps at most of the providers
are useless and won't tell you
the second part of the solution.
It took me 2 days and 4 reps
at Comcast to find this out
and 10 hours of trying to
clean my Mac...
which they will always
blame.
Best of Luck, Tom

You have omitted all useful information from your post,
Things like, what mail system, there are many, which Mac, many of them as well
Time to describe what you have and what error messages you receive, can't do anything with your question otherwise.

Icloud SMTP server is offline, can't send out mail

I am having a problem, can't send out mail with my iCloud account. Password is ok, but it says "offline" On Mavericks OS

You might want to try signing out of your iCloud account, then back in. Go to System Preferences>iCloud, click Sign Out, choose Delete at all of the prompts, restart your Mac, then sign back in.
This deletes the account and your iCloud data from your Mac, but not from iCloud. It will reappear on your Mac when you sign back in, after a brief delay as it redownloads.

Can't send e-mail w/new POP settings...

Hi, all,
I updated my POP & SMTP settings as demanded by Verizon and I now can't send e-mail from one of my subaccounts. I get the error message:
An error occurred while sending mail. The mail server responded: 5.7.1 Authentication is required to send mail as <r******[email protected]>. Please verify that your email address is correct in your Mail preferences and try again.
I don't use that e-mail address, which I guess is the "technical" address I got when I signed up. The address I'm trying to use is s******[email protected], and that's the e-mail address that is set up in the account on my e-mail program (Thunderbird). I never use the address the error message is referencing.
Any suggestions on how I can fix this most annoying problem?
Thanks!

Without seeing your settings, it's going to be somewhat difficult to guess the problem. I would take another look at your SMTP (outgoing) settings, and verify that the server is set to authenticate with the correct username and password.

Mail can't send out mail anymore....

hey everyone,
I just downloaded the 5 new apps a few days ago, and everything worked great, until now.
I can receive emails, but i can't send any emails out.
When i touch send, a message pops up saying,
"Cannot send mail. The connection to the outgoing server "(null)" failed.
What does this mean? The messages I've tried to send out, just keep on filling up my outbox. What does this mean? Am i missing something?
Thanks in advance for your help

Hey vanlan,
Make sure you are using the correct email settings. Check the email provider website or use common settings found here: http://www.apple.com/support/iphone/mailhelper/
Try the tips in this article:

Most Internet Service Provider email accounts will only allow you to send email on their server when you are connecting to the Internet over their network connection.

How can I send out mail to multiple addressees?

I want to send out a a mass mailing where I can begin my mail by personalisng it to 'Dear John, Jane...... or whoever. How can I do this with using Mail?

I Googled - I don't use Apple's Mail - and it seems that you need third-party software: this was one of the top hits - http://www.macmassmailer.com/mac-mail-group-email-list.
Good luck,

I can't send out mail. the prompt is telling me that I am not connected to a server. What do I do?

How do I connect to a server to enable me to send mail

Well you can start by adding detail - any detail that might help.
What mail application are you using? Mail.app? something else? What else?
Your signature says you use hotmail - is this hotmail you're trying to configure? or something else?
Is the problem with this specific email account? or all (do you have more than 1?)
Without these (and likely more) answers there's not enough to go on here.

Thanks.

The problem was with my server configuration.

lots of people seem to be havgin a problem sending email from iCloud webmail.
does your email address have uppercase characters in it?
if so, try creating an alias in lowercase (go to preferences in iCloud webmail and select 'accounts') and see if email sends okay from that

I am receiving a connection error and can't send out yahoo e-mails. I can surf and use another browser with no problem what happened all of a sudden with my firefox?

I can't send out e-mails! I get a connection error message.
I can receive messages, surf the web via Firefox.
The only related thing to this occurrence is that I received a notice from Firefox recommending that I disable a Skype extension, which I did. Not sure if this is connected.

1. Change your server to outgoing.yahoo.verizon.net - This is the correct outbound server for Verizon Yahoo accounts.
2. Make sure the setting for "outgoing server requires authentication" is selected. - It should auth with your vz username and password
If you are still having trouble, post the error. (The error you've posted here is for the wrong server.)
Well, I had already done those things before. The message I got when I tried is:
An error occurred while sending mail. The mail server responded: From address not verified - see http://help.yahoo.com/l/us/yahoo/mail/original/manage/sendfrom-07.html. Please verify that your email address is correct in your Mail preferences and try again.
I had input the email address without the @verizon.net extension. That's exactly how I input it in the pop3 set-up for receiving e-mail and it works there.
So I went to the link that is referenced in the error message. It basically had me go to my Yahoo mail account page. I was directed to add an account with a different email address. A verification code was then sent to me via email that I then had to input into the new account's setup page in order to activate my Yahoo mail for smtp use. Once I input the code and validated I was then able to send e-mails just fine with Thunderbird. I was able to use my @verizon.net email address and not the new account I had created.
Bottom line - I had to activate/validate my account before I could send email. I had not read about this anywhere when trying to figure out what was wrong.

TS3276 Why can i suddenly not send out mail using mail through my ntlworld account

Why can I suddenly not send out mail using Apples Mail. My mail server is Ntlworld. I can send mail by going to Safari and loging into my mail account, but i would prefer to continue using Apples mail and my address book. Does anyone know what my problem could be. I haven't altered any settings.

If you're having trouble sending mail, then either the SMTP (outbound) mail server settings — the server, the port, the user, the password, and whether SSL is in use or (unlikely) not — are incorrect, or the mail server is offline or has been reconfigured.
The SMTP (outbound) settings are in Preferences, but are buried rather deeply. Select Preferences > Accounts > select the account > switch the outgoing mail server (SMTP) to Edit SMTP Server List... and then select the SMTP server from the list, and verify that the settings are correct with your ISP, and that your username and password are correct.
The required settings vary by your particular mail ISP; you'll have to check with the ISP for the server and login details.
To test settings, select Window > Connection Doctor > then (when the tests fail) show the details, and (if you can't sort out what happened) sanitize the settings and post the output here.
Caveat: do not repeat password tests with the mail server, as various mail providers can be configured to assume these are a password brute-force attack, and lock out repeated login attempts.
Caveat: never, ever, ever, ever, ever, ever, ever not-at-all enter a password when Mail pops up a dialog box with the "OMG YOUR PASSWORD IS WRONG!!!!!!!!!!! PLEASE ENSURE YOU CANNOT LOG IN AGAIN!!!!!" dialog box. (I'm paraphrasing that error dialog box slightly.) The correct answer to that Mail.app password dialog box is almost always "cancel" button. Passwords stored in Keychain generally don't get lost or corrupted, and trying random passwords as that dialog box encourages just gets you locked out of various servers, and...

I can't send out photos using I message on my iPad 3

Can't send out photos using I massage on my ipad3 with ios6

It depends on the type of e mail service you have. If you have a pop account you cannot create new folders. If you have an imap account, you can. As an example, comcast.net are pop accounts. Gmail.com addresses are imap accounts and you can set up folders.
If you are not sure what you have, put the pad in landscape and in the left side, touch the account button for your service. You should see inbox, draft, delete and trash. Look at the top. If there is an edit button, touch it and you can add folders. If the edit button is not there, you have a pop account and cannot add folders.

"connection denied due to dictionary attack" when I try to send out mail

Hi--
I got this message "connection denied due to dictionary attack" when I tried to send out mail today. It was the first time I ever saw anything like this. I thought it was a problem with the mail server from my website, but no one else had the problem. After about 12 hours, it suddenly stopped...
Was I being hacked? Was someone trying to send out email/spam through A)my home machine or B) my website? And if so, how can I protect myself from it?

Well you second post was the correct question because I was going to say you got a second hand macbook pro, didn't change anything, and expected mail to work with your ISP. The mail settings were thus those of the previous owner. So you are correct to ask what your ISP's settings should be.
Unfortunately I can't answer that. You have to get that from your ISP. They proably have a web page for it.
You need to know:
Incoming mail server (pop)
Incoming mail server login name
Incoming mail server password
POP port
Does is require SSL?
Authentication for using POP server (probably password)
Outgoing mail server (SMTP)
Outgoing mail server login name (probably same as incoming)
Outgoing mail server password (probably same sas incoming)
SMTP port
Does is require SSL?
