Unable to Send Mail to a Specific Domain

I've searched the forum but found no answers.
I have a new iMac and a MacBook, both running 10.5.1
The email settings are identical on both computers (I checked many times over).
I can send an received mail on the MacBook, but can only receive email on the iMac.
Well - SOMETIMES, it will send email on the iMac. The majority of the time I get the message where I can select another outgoing email server (I have only 1) - I use the connection test, and everything shows OK. What gives??
UPDATE:
After some trial and error - I am finding that I cannot email to people with a certain domain. For example, My ISP is Cox.net (and so is my email) - and I cannot email to myself or anyone @cox.net. I can email out to people with Gmail email address though. I am confused even more now...
I have no one in my address book. Is it possible that some sort of corruption has occurred related to certain email addresses? If so, how would that be fixed?
ANOTHER UPDATE:
I found that if I select "remove from previous recipients list" for my own email address, I was able to send an email to myself.

On my MacBook (10.5.1) the port setting is in Preferences>Accounts>Advanced. It's grayed out on mine, why I don't know. I migrated settings from my iMac (running Tiger) when I bought it, and haven't tinkered with it at all. My settings also include password authentication. As I said, I've used it at a several airport lounges overseas, without any problems.

Mail to a specific domain not being delivered

We are able to send/receive emails to external domains and everything seems to be fine with our exchange server except when we try to send mails to this one domain @ ju.ahg.com.sa
Upon troubleshooting further, we came to know this domain doesn't have a valid MX record.
Yet the mails to this domain get delivered by gmail and other email services.
If we use the SMTPDIAG tool, below is the output.
Note that when its done from our domain, it gives error, when done from gmail ...its success!
How can we fix this issue?

You are right, when I looked up using MXTOOLBOX.com ; this domain seems to have a valid MX record, but no valid A record. Would that be the cause?
Also, I tried through the command line, and it seems my DNS server is unable to resolve, so I am not even getting the MX record.
I have 2 DNS servers , how can I try these commands to use the other DNS server ;
as I tried on both servers, It gives the name of the first server only and says it can't find this domain: Non-existent domain.

Unable to SEND mail using Activesync in Exchange 2010 server on iPhone or Windows Mobile 6.1

Hi All,
We've been setting up a new SBS 2011 server for a client this week. Everything is working, except the staff have 4 x iPhones to connect with Exchange ActiveSync.
There are 2 x iPhone 4's and 2 x iPhone 3Gs's. We can setup the Exchange accounts on each of the phones and they are all able to sync mail and calender etc with the server.
The problem we have is when any of them try to send mail from the phone, it gives an error : "Cannot Send Mail - An error occurred while delivering this message" and it sits in the outbox on the phone.
The newsgroups and forums are littered with people having issues with IOS4 and Exchange 2010 but most of these are from June-August 2010 when IOS4 version was around 4.00 or 4.01
A lot of these people had iPhone 3 handsets running with IOS 3.1.3 which worked with Exchange 2010 but when they upgraded to IOS 4, they had this problem sending mail.
It seems that for most of them, the fix came in the form of IOS version 4.1 which fixed the send issue for them.
We have a variety of Hansets and IOS versions (including an iPhone 3Gs running IOS 3.1.3) but are unable to send mail from any of them:
iPhone 3Gs    IOS 3.1.3
iPhone 3Gs    IOS 4.3.3
iPhone 4       IOS 4.3.3
iPhone 4       IOS 4.3.5
I was surprised that the iPhone 3Gs running 3.1.3 was unable to send either as nearly all the forums etc I read with this issue said the iPhone 3's worked with that IOS version.
Today we used a test iPhone 4 handset from our office to connect to an almost identical Small Business Server 2011 we setup two weeks ago for another client.
The test iPhone 4 was able to connect, Sync and Send email on that server but when set it to connect to this SBS 2011 server, it gets the "Cannot Send Mail" message the same as the others. So clearly the handset is working (on the other server at least),
it must be something misconfigured in this Exchange server right?
We ran the Exchange Remote Connectivity Analyser on the Exchange server and got green ticks across the board.
Outlook Web App and Outlook Anywhere both work normally. Everything we can test on the Exchange server works except sending from any iPhone.
Having said all that, I just setup a Windows Mobile 6.1 handset to sync with the Exchange 2010 server as a test, and it appears to have the same issue.
It will connect & Sync Mail, Contacts and Calendar but if trying to send an email from the phone, it will just sit in the outbox.
Does anyone have some insight into what the problem may be?

Further to this .. I found the solution on a MS Exchange 2010 support forum.
It was not a certificate or firewall issue, looks as thought the “Accepted Domains” in Exchange Mgmt Console –
Org Config – Hub Transport cannot have any spaces in the name field.
I had some spaces and the emails were not downloading fully and able to send. Once I removed the spaces from the Name field and
restarting the Exchange and IIS services emails were now being sent and received ok.

Unable to send mail on ipad

I am unable to send email to a specific address from my iPad. I can send from iPhone and iMac this address. Any ideas. Just updated all mobil devices to iOS 7.0.6 but the problem still exists.

I solved my problem by entering user name and password in the outgoing server fields in my mail account. It says they are optional but not for me.

Unable to send mail to some addresses after move to Leopard

I am not sure, whether I am in the right forum with my question. If not, please tell me where I should go.
I am traveling a lot for work and have clients in many countries. Since 2004, I have been using Mac laptops and have not encountered any problems sending mail through clients' LANs, from my own place to clients, or from any number of hotels to clients. I migrated from Tiger to Leopard on the day the latter OS became available.
Since the move, I am experiencing a problem sending mail to one specific client. I can no longer send mail to my various contacts within that client's premises (all of whom share the same domain name) from outside. I also cannot send mail to any of those contacts when I am hooked up to the client's network (but not the domain) whilst within the client's premises.
I use Mail and a mac.com address. I do not use web-mail. It is further noteworthy that messages from my side without attachments will sometimes (perhaps 20% of the time) go through. However, messages with attachments never go through. I have discussed the matter at length with the two IT-experts at the client (a government office) and we have not been able to come up with suggestions.
Since I am now forced to use a USB-stick to exchange info with my client, I would much welcome your suggestions as to the cause of the problem and possible solutions. Many thanks in advance.

Thank you for taking up the issue, Type17. The mails do not disappear, they remain in my outbox (on my Mac). The intended recipient does not get a message. I, for my part, see a box with the message 'Cannot send the message using the server 'smtp.mac.com: myloginname'. The server name is highlighted in blue in a box below and I get the choices: 'Edit message', 'Try later' and 'Try with selected server'. None of these resolves the problem. The last option, i.e. 'Try with selected server', is a bit strange, because pressing the button 'Edit server list', shows only the server already mentioned. I have tried 'Connection doctor' several times over the past months, but this consistently gives me a green light against the smtp and the message: 'Connection and login to server successful'.

Unable to send mails from Azure SharePoint 2010 VM

Hello All,
I have created Site-to-Site VPN in azure to my on premise, and i have configured SharePoint 2010 environment in that. Then i have configured outgoing mail settings for a web application in that VM, but i am unable to send mails to external domain from it.
But i am able to send mails from my on premise VMs to external domains.
Thanks

Hey There,
Azure does not support smtp relay, you may want to use SendGrid (which working with Microsoft Azure).
After registration you get 400 E-mail per day free of charge.
From technical aspects youll get SMTP server, Username & Password which you can fill in your application.
Hope it helps.

Mailx unable to send mails to outside world?

hi
on a solaris sparc 9 environment mailx command is unable to send mails to the outside world. What could be the reason & needs to be checked?
thanks

sounds basic, but what's your entry of malhost in /etc/hosts pointing to? If it's not there, add the entry with the IP address of your SMTP host.
when sending test mail from mailx, have another window open thats tail-ing the contents of /var/log/syslog - that usually contains good info about sendmail.
another thing worth checking is the rules on your SMTP gateway. If this is a new host, it may need adding to the list of authorised relay list. Also check to see if the SMTP host is alowed to relay mail outside of its own domain too.

Unable to send Mail from POP account

I have an Iphone 4 and have upgraded the IOS from 5-1 to 6.1.3. Since then I have been receiving all my mails but i have been unable to send mails from my POP account. the notification "Cannot Send Mail. A copy has been placed in your Outbox. The receipient, "xxyyzz @ gmail . com " was rejected by the server" displayed. Please Help. the same thing happens when I configure my POP account on my Son's Iphone4, and there is no problem in receiving and sending mails from my Outlook. Please Help!!!!!
Can i revert back to IOS5.1.1?????

Contact your email provider and get the correct settings to use for the outgoing mail server (SMTP) on a mobile device. If it's email provided by your ISP, they have likely blocked email from outside their network from relaying to prevent spam.

Unable to send mail- mail remains in outbox and I receive error message

Ok, I have used Mail for years. All of a sudden I am unable to send mail. The mail goes to the outbox and then I receive the following error message.
This message could not be delivered and will remain in your Outbox until it can be delivered.
The server "smtp.mac.com" refused to allow a connection on port 25.
I can connect to webmail of course and send mail that way.
I receive mail perfectly.
Not sure what to do...??
Thank you for any help with this.

Read the following article, which applies to all versions of Mac OS X (not just Mac OS X 10.4.2 and earlier as the article states) and can be useful for other mail accounts as well (not just .Mac):

I don't remember much of Acrobat 9...
What email client are you using? Are the Acrobat preferences configured to use that email client? Is it running when you try to send that document?

"Unable to send mail" using Verizon email account

No matter what I try, my Incredible will not send an email using my Verizon email account. I receive emails but cannot send. I've verified the account settings numerous times and the verifications always work. But I still get the "Unable to send mail" message. Initially I thought it was the port but I've tried both 25 and 587. Neither work. I know I've sent messages before but it's been a while. Anyone have any ideas?

I tried SSL with 25 and 587 (Verizon recommendation). Still no go.
BTW, there isn't any way to save the Mail size limit and Download options is there. Every time I go thru this I have to go back and set these up again.
Thanks again for your help.

HT1277 i can receive mail but unable to send mail

i can receive mail but unable to send mail

I'm yet another person who upgraded to Maverick OSX. I'm now thinking, "BIG mistake". Mail was working perfectly. Then, last night, Mail stopped sending.
I've checked everything. Comcast servers are set up correctly. Mail works fine on my ipad, but will not send. It gives me a SMPT error of "Cannot send message using the server comcast.net--authentication rejected" Comcast.net (Offline). I can not get it back online. I've also tried the fixes here, but there is no info.plist by those names in my library!
Anyone have any other ideas how to get this working again? Apple's OS's have been pretty decently stable in the past. I had no thought that the upgrade would be so problematic. Live and Learn.
Thanks for any suggestions.
