email attachment Undeliverable

Tried to send a 8mb of attachment to one of the recipient. But I got bounceback message:

"This message is too large to send. To be able to send it, make the message smaller, for example, by removing attachments.


Diagnostic information for administrators:

Generating server: Server1.xxx.com

xxx@xxx.com
#< #5.2.3> #SMTP#

"

I checked the user's mailbox receiving message size on exchange, it was set to 51200kb. So what is the problem??

Is the bounce message coming from your mail server or the recipients mail server?

Is that Exchange 2003?  Check both in Global Settings>Message Delivery properties and in the SMTP protocol properties for sending limits.

from recipients mail server. Yes it's Exchange 2003. why I need to check the global setting?
it should override the global setting

and you can see in global setting, it's set to 10240 kb. the attachment it's only 8 mb

You stated that the message is coming from the receiving server, so it doesn't have anything to do with your local settings. The receiving server obviously has a lower limit.  There's nothing you can do except send the information to a different email address (if the recipient has one) or send it by snail mail or fax.
You say the recipients server is the one generating the message... which looking at the message is "server1.xxx.com".  Do you manage "server1.xxx.com"?  I guess I'm confused about which one of the 2 is the Exchange server you're managing.
Oops sorry hypercat... didn't see that you already posted.

I manage server1. so the setting you see in the screenshot is for server1.
I sent a test email with 8 mb attachment from my hotmail to server1 and I got the Undeliverable message

the attachment are just 2 pdf files. I even zipped the 2 attachments, same result
You will have to split them into 2 separate emails.

I zipped the 2 pdf and checked the size before I attach to outlook, which is  7.89 MB. So you are still saying it's not under 10 mb in smtp format?? so how do I find out what 's the real size in smtp format?

>>I'm not sure what problem you're actually trying to solve at this point.  

my whole point is to enable the ability for them to receive the 8mb attachment.
I already increased the limit and still not working
Have you increased the limit both on the Message delivery properties and the individual user's delivery restriction settings? Both of those settings have to be high enough to allow the maximum size you want.  My advice would be to set the Message Delivery properties to the maximum size and then set the users' settings to "use default limit."  

Have you restarted the SMTP and Exchange services after changing the settings?

Already did that

How about your SMTP connector - any size restriction on the Content Restrictions tab?
Avatar of okamon

ASKER

no restriction

Sorry if you've already checked this but can you check the Messages tab on "Default SMTP Virtual Server"?  The screenshot you attached a few above is from the AD user account properties.

Should look like this... with whatever values are your own.

If you want to know the exact size - this will show up in the tracking logs.
There is no formula for this, just like there is no formula for knowing exactly how much compression you get when zipping a file.

finally I got it to work. It seems it's a big in exchange 2003. I put the send and receive size the same in the default message delivery property. it was different before

it was both 10 mb there before, but it seems plus the attachment header it exceeds 10 mb
