451 Temporary local problem

[TomerP]

Hi all...

when trying to send email (using webmail or outlook) users of the server seem to be getting this msg (copied from OE):

An unknown error has occurred. Subject 'testing', Account: 'TnS Int - Main', Server: 'mail.tns-int.com', Protocol: SMTP, Server Response: '451 Temporary local problem - please try later', Port: 25, Secure(SSL): No, Server Error: 451, Error Number: 0x800CCC6A

Now, i've read the only 1 thread here about this problem and it seem to be my case is different, there isnt seem to be a DNS problem (anyone from every where can access the server).

i've copied the last few lines recived on the mainlog file from exim:

as you can see it seems like the problem is on the server itself.

a little more info:
This server is running the latest DA, it has only been installed a week ago, in the first day or two emails sending was fine (or so it seemed )

Any ideas ?

Thanks,
Tomer

You have the option in your exim.conf to send email to clamav and it can't find the socket file that should have been created. I would try insuring that clamav daemon is running and the socket file /var/run/clamav/clamd exists.
