Exchange 2003 emails

I have Exchange set to defaults so allowing send and receive limits of 10MB and AD users set to default limits. I have users that are able to received 6mb size emails, but anything over this limit the email seems to disappear into thin air. It only appears to be emails with large attachments. I can see the email coming through the firewall then does not land in the inbox. There are no undeliverable messages sent to the sender? Where can I look now?

Find the mx record of your domain.Check where does it point.
Then,do a telnet from an external machine and see the size verb. It is normally in bytes.ensure that it is set to 10 mb.
Are you able to send a 10 mb email internally?
Wt firewall you are using ?

please check your antivirus or spam filter blocking this emails?
Are you able to see 10MB email in your Firewall.Do check for the SPAM filter.In either of the two the email is getting blocked.

You also need to see weahter you are able to send 10mb file as attachment internally and externally

Yes I can send 10mb internally, but not over 10mb. I have done tests and can receive 7mb attachments but not 8mb attachments?  Its a Fortigate firewall 100A. I'm not very familiar with them (new to the site) so I'm not 100% sure where to check. Nothing seems to be blocking. If I send an email internally over the default in ESM which is set at 10240KB I get the undeliverable message over the set limit for the mail box or your box is full. When I send an email over the 10mb from an external address I get a message back alerting me that it is over the receivers limit! Mx record is at 10mb! Any other ideas?
