451 Failed in remote data - psmtp   

Hi,

Using Exchange 2003 with Postini and a Watchguard firewall. 
Problem: If you send an email to anyone in our company with a large 
attachments (over 5M) you get the above error or the following error "552 552 
Requested mail action aborted: exceeded storage allocation." 
I've tried from gmail, hotmail and have had external people try and all 
getting similiar errors.
Our Exchange limits are set to 20M, Postini does not have any limits set and 
our Firewall has no email filtering set up. None of our exchange mailboxes 
have storage limits on them. I can send emails with large attachments 
internally to another exchange users. We can also receive emails with 
attachments of 5M and lower with no problems.
This problem has just started happening. No changes have been made on our 
servers or firewall. 
Any ideas?

Cheers in advance
Dee

Did you try shutting down your spam filtering services if there are any 
(Appart from Postini, you may have your own internal scanning engines)?

Hello Dee,

I'd also check on your Postini System Administration console - check the 
spool allocation, and the message limits set for Max Message Size.  If you 
increase logging on SMTP, does it show the connections being made, and the 
rejections happening?  At what point does it show the failure?

We have no spam filtering other than Postini. However: I've removed myself 
from the Postini filtering to try and eliminate that. We are going to do a 
test to see if it is our Firewall next.

Watchguard does have SMTP proxy filtering to filter file extensions and 
things like that, if you send the mail internally do you get the 
rejection? If not it is outside your exchange.
