Exchange Problem Sending E-mail

Hi -
Our certificate expired and we renewed it - we are able to remote on workstations using RWW (SBS 2011) but when we try to send mail we get the following message -

Your message wasn't delivered due to a permission or security issue. It may have been rejected by a moderator, the address may only accept e-mail from certain senders, or another restriction may be preventing delivery.

the rejection is from our own server.

Any suggestions would really be appreciated.

Thanks
Rich

Hi,

How are you trying to send the email - are you using OWA or Outlook for example?

If Outlook, have you rebooted both the server and the client since updating the certificate?  If not, try that, and post back if that helped or not.

Thanks,

Alan.

Thanks Alan -

The clients are using Outlook and when I tested I used OWA - both had the same problem.  I will reboot immediately and let you know.

thank you very much.

Hi Rich,

I would power off the workstation(s), then reboot the server, then power on the the workstations.

If practical :-)

Hi,

Is there no specific error number such as:

#5.7.1 smtp; 550 5.7.1 Requested action not taken

(Probably not that specific one, but something like that)?


For the account that you are trying to send from, please go to the EMC, find the user, right click, properties, mail flow settings, Message Delivery Restrictions, Properties.

If 'Require that all senders are authenticated' untick that box, apply, ok / ok etc and then try again.


Thanks,

Alan.

First - let me thank you for hanging in with me - really appreciate it.  I've been working on one problem or another all day.

yes i have remote.xxx.com #550 5.7.1 Unable to relay ##

I am beginning to believe that it might be a smart hub issue.  I asked the client for a user id and password for the cablevision account.

I put an invalid user id and password and the e-mail got stuck with an authentication error.

Thanks

Hi,

Not sure what Smart Hub and / or CableVision are, but it sounds like you might be referring to the ISP?

Have you tried sending an email from a client connected on the LAN, internally to another user?  Does that work?

Where are you getting the above error you started with?  What is returning that?

Thanks,

Alan.

Hi Alan,

I wanted to close this up and let you know what had happened.  It seems as if everything we tried caused more problems.  Initially the certificate expired - I attempted to install a new one and we had a problem with installing it.  Ultimately I got it in and we were able to access the server through Remote Web Workplace  (RWW) which requires a valid certificate.  During the initial process we thought that maybe the problem was with the router - I asked the client to pick up a replacement router and I would walk him through setting it up with a static IP - He said he had in the office.  So after working with him to setup the router we were able to access the server through RWW and we were still receiving e-mails but could not send.  

This morning I contacted Microsoft and they did a few things but we could still not sent mail.  We could send mail internally but not externally.  We also would go to 10.0.0.2 (the server) whenever we tried to go to any website.  Ultimately the Tech thought the problem with the backup router.  Sure enough we switched it back to the original router and it worked.

thanks for your help
