Clients are behind ISA Firewall. Isa is used only to share and protect
(using firewall client, no NATs) connection. Mai server is in ISP, POP3 and
SMTP access are granted.

OK- So, where does the ISA server come into play?  Does your ISP use it to
publish SMTP on the Exchange Server?  Or are you directly connecting to the
SMTP server from behind ISA via the firewall client?  Is it always the same
2 Meg file or different ones you have tried?  How many clients have you
tried it on?  Is it the fw client or SNAT?
What kind of connection is in use?  Can you give us any more information?

I have done it many different ways, even Client-to-ISA-to-ISA-to-Exchange
and visa-versa with no problems.  Details would help!
