Email is not going to outside domain from One User of my company Domain?

Hi,
I have a problem with one of the user on company domain which is configured on MS Exchange Server 2003 on client side windows XP.
That particular user cannot sent the email to any domain like hotmail, yahoo, gmail, or any other Company's domain. Please let me know how and from where this would be solved.

With BR

Is the mail client being used Outlook?
Is it configured as Exchange / POP / IMAP?

If POP / IMAP - check that there is no spelling mistake in their FROM address.

Things to check:
---Sender Filtering---
Open Exchange System Manager
Expand Global Settings
Right click on Message Delivery and select Properties:

- Check to see if the sender is being blocked via the "Sender Filtering" tab

---User Exceeded Mailbox Storage Limit---
In Exchange System Manager
Expand Server
Expand <Server Name>
Right click on First Storage Group (or whatever storage group the user is in) and select Properties
Check the Limits tab.  Look at the "Prohibit send at (KB)" and see if it's checked and what value is being used.  Compare that number to the mailbox size of the user who cannot send email.

---Check the SMTP addresses of the user who cannot send email and see if the default email address is something other than your domain name.

If none of those work, can you post the non-delivery that is getting returned to the user who cannot send email?

it sounds like you don't have the smtp portion of your pop3 account configured to require authenticatoin
check you account settings, outbound settings and make sure this is enabled

Hi,

I am not so familiar with Exchnage 2003 as we are using 2007 and I forgot the Exhcnage 2003 GUI settings since I did my MCSE 2003 lonf time back. However, can you check that the user has a full ligitimate SMTP address e.g if you domain is Example.com confirm that the SMTP address for the user is user1@example.com. You may have to go to your user mailbox settings and edit the SMTP address if it is wrong.

I remebered once that my brother told me in his company they are modiying SMTP for the users that they don't want them to send or receive mails from outside of their organization. They are removeing @example.com domain so external can't send mails to them.

Hope  this may help you

Hi endital1097:,

For port 25 assumption, I think this is not he case here since the problem is only for one user only as oyesali explained in this posting. I believe if the ISP is blocking port 25 then all the users will not be able to send or receive mails.

But good point of port 25 that there are some antivirus application are blocking port 25 (like in our company we had a problem where mcafee was blocking port 25 then we solved this). However this isusually will be blocked on your SMTP server but it worth to check if your client machine can telnet port 25 to your smtp server. from command pormpt type: telnet [type smtp ip address] 25. If can't at all then definitely there is something blocking the connection from that particular client machine (check AV or FW settings)

you can google on how to use telnet to send mail to users . check this link http://www.simplescripts.de/smtp-check-port-25-telnet-command.htm
you can find on Google tons of similar sites explaining telnet to your SMTP server

Hope this help
