[exim] proble m in sending mail from our sites to ceratin si…

We are experiencing trouble in sending e-mails to certain sites from our Exim Gateway, which is 4.60. We don't know whether it is exim or our firewall which is causing the problem. Ordinary e-mail goes through, but e-mail with attachments fail:

Below is an example:

Site Shakespearesglobe.com
Our site: westminster.ac.uk (gateways, isls-mx10, isls-mx20, isls-mx30)

Shakespearesglobe.com says:
"MTU size is currently set at 1404. Our communication line is a 10MB Managed Internet Line. We don't experience any problems communicating with any other organisations with our current MTU size. How have you resolved this problem with other organisations?"

We at isls-mx30, compiled exim with 4000 MTU, but that failed to solve the problem.

Any body has seen the problem like this before?

Thanks in advance.
