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

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?

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.
