Can Receive But Cannot Send E-Mail

Bit of an odd one here. I have searched the site and found nothing similar so here goes:

We can receive but cannot send E-Mail. It became apparent that we had a problem at around 12:30 yesterday. We are getting a poor response when pinging our DNS server [averaging 8 - 12 ms] so perhaps that is related. I can't find the cause of the slow reponse from DNS. But I do not think that DNS alone could be the problem because logon times seem to be unaffected [If DNS was down logon would slow down or not be possible at all?]

Anyway back to the subject at hand: Anyone seen this problem? At the moment I am baffled.

I should have pointed out that our E-Mail is web-based: Although I can create this new thread and post it here I cannot create a new 'page' on my E-Mail account and send the message at my workstation or at the server. And this problem only affects messages with attachments.

Have you phone you email provider, as its web based and obviously on more than one machine then its probably a fault on their end.

Could be wrong though but worth a shot.

It is affecting our Grid E-Mail provided by our ISP [HGfL RM EasyMail] and other web-based E-Mail too: Googlemail etc, so I think that might not be applicable. I have asked our Grid if there is a problem they know of and they say it must be our end.

OK: An update: It now seems to be my user on the network that is affected. I am going to test it at home to see if it is purely a domain problem or something more....

Have you tried a different user account then? If it is yours, then backup your work in your user account, delete it, put it back, copy work and see if that cures it ?

Or did i miss something there

Another Domain Technician/Administrator has found she can send E-Mail when I cannot. Iam strting to think that it is something to do with my domain user preveting me from sending these messages with attachments [at the server or at my workstation] So I am going to try the same thing at home and hopefully eliminate one of the unknowns.

OK. So now I know I can E-Mail with attachments from home [I didn't expect other result to be truthful]

So I guess it is something about my user on the domain at work, since a fellow technician can E-mail with attachments on the same domain. I guess I will just have to delete the user as accura2000 has suggested, but what could cause this?

It could be just a corrupt username in the AD. I had a problem where a user could not logon, kept saying password incorrect although i had reset it 10 times. Only solution was to delete and put the user back on. Worked a treat.

It could also be something to do with your IE settings for your domain username, again the easiest solution i would say is to remove and place back the username in question.
