I receive emails but can't send with Optimum on my new iMac

We have a replacement imac that can receive emails but can't send any. We have spent hours with Apple and Optimum and the problem has yet to be resolved! Any ideas?

I don't really know what you tried, so I can only suggest you start from the beginning:

Please describe in detail what happens when you take all the applicable steps in the support article. That's the starting point for any further efforts to solve the problem.

Hi johnnytoo!
I know it's aggravating when you need to send an email and it doesn't go through! I have a link that provides step by step information from Apple's website that should resolve this for you.

Try this first - Reset the iPad by holding down on the Sleep and Home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider - let go of the buttons. (This is equivalent to rebooting your computer.)
Or this - Delete the account in Mail and then set it up again. Settings->Mail, Contacts, Calendars -> Accounts Tap on the Account, then on the red button that says Remove Account.

I can receive email but can't send on my ipad2

I can receive email but can't send on my ipad2. It says 'rejected by the server'.

I would that that your smtp settings are set up wrong
I would verify them 1 by 1 against the setup guide from the mail provider
if they were the same I would suspect that your phone company are blocking the ports
required by smtp in which case I would take contact to them and ask why

You will most likely need to put a password for your outgoing mail server, go back into the mail account and put in the password, same password as your incoming mail server.

Exchange Server 2007 OWA users can receive email but can't send

Hi,
I have an Exchange server 2007 in an SBS 2008 environment with POP3 connector configured and working fine , smtp send mail connector configured.
Now users can connect to OWA, receive email but cant not send.
smtp connector works fine from Outlook client. Tried to track the emails from exchange server management console and I get the
SEND DELIVER SUBMIT TRANSFER.
The emails go to the sent items folder, but it never reach the recipients.
Have been troubleshooting for a while without succes. Any help will be most appreciated.
Regards
Faisal

POP3 is a single mailbox client mail retrieval protocol, not a mail transport protocol.
Any attempt to use it as a mail transport protocol is a great big kludge.
Exchange is designed to connect to the Internet using SMTP.
No version of Exchange has a POP3 connector.
I recommend that you post this in the SBS Forum: http://social.technet.microsoft.com/Forums/en/smallbusinessserver/threads

Can receive emails but can't send any

Can receive messages but can't send any. What setting am I missing?

I had this same problem with my zoho mail account. It started when I changed my email password on the computer....Long story short I have been going crazy for a few days. I could receive mail, but couldn't send anything from that account! (Fortunately I have two other accounts which are a different server - gmail.) I turned my iPad2 off then on again...I did a sync with iTunes...I deleted the account and then added it back...Still it would not send..Just receive!
I did finally get it fixed, but it took about an hour poking around and looking for help here.
There were several problems:
1. Somehow the server port numbers were incorrect. So when I added the account back in, I found that the "incoming server port" was not correct and fixed it. But I didn't see how to check the "outgoing server port." - somehow in the setting up process, that just wasn't exposed.
2. Eventually I found the "outgoing server port" here: - Go to Settings - General - Mail - Account. Then tap on the Account you need to fix. Check the information there to be sure it is correct.
THEN: tap on the white bar just below the word "Outgoing mail Server"
That takes you to "SMTP"
You will see a primary server, and "other SMTP servers"
Somehow I had 3 there that were the same account server name (zoho) ..all with the wrong port number!
But even after fixing each one, I still couldn't send mail. This led to problem number 3:
3. Apparently having 3 of the same account was a problem. After I deleted all three of the accounts, then tapped on "Add Server" and entered the information back in again. Bingo, I could send mail!!
I don't know why, but now my "Primary Server" says "Not configured - off"
And all the "Other" servers say "off" as well.
But it's working so I am going to leave it as it is.
I hope some of this is helpful.

I can receive emails but can't send them. Auto set up created mail account separate from account migrated from a PC. Migrated account receives but doesn't send; other account didn't work

Phoned internet provider, TPG & talked through resetting passwords then the migrated email temporarily allowed emails to send, then quit again, but still receives emails.
Why will my Mac receive emails but not send them? The mails settings for POP & SMTP are same.
Closed the original mail account on the PC but didn't help - had to reopen it to send this email.
Detail from Mail Connection Doctor on my MacBook Pro, under WROTE says:
VIDL 437,
then later quits.
Is this relevant? Does this mean anything?
I'm a bit technically challenged.Good at Adobe software but not mail, internet or hardware. Has anyone fixed a similar problem?
Theger.
