I have been able to narrow down the point where the corruption occurs.

All the messages that arrive at the Imail Server, arrive with the
attachments intact without corruption.  From the Imail server I am able to
forward them to an external mail server (earthlink) then retrieve from
Earlthink with POP3.  These all test AOK.  So all functioning of SMTP is
AOK.

Corruption problem only happens at one point...  A clean copy residing on
the Imail server that is then retrieved by POP3.  In this process is where
1/4 of the images receive various levels of corruption.

The computer used to receive has been tested ok with receivng other pop3
messages, as well as a test on an alternate computer to retrieve POP3 from
IMAIL and the corruption follows the retrieval.

I also tried upgrading the 8.0 to the latest rev level of IMAIL and it made
no difference.

Basically, POP3 retrievel of messages from an IMAIL server is the ppoint of
corruption.

All these other tests also confirm that memory is not an issue as it only
occurs with one specific action,  Which is consistantly repeatable.

Any other ideas???

Thanks

Mike

Sever has a 1gb of ECC (error correcting ram) and has also had memory test
run against it and it all checks out.

No other applications on the server, such as Oracle, sqlserver or IIS have
any problems.

I wish it was as easy as changing the memory.  :-(

The only times I can recall having seen attachments corrupted from passing 
through an IMail server are when either [1] there is corrupt memory on the 
server, or [2] a header/footer is being added to an E-mail with a missing 
body and obscure encoding method.

#2 almost certainly isn't the case (that is very, very rare, and would 
normally happen to 100% of the E-mail passing through the server from the 
same mail client).  So I would check the RAM as the first step.

Note that IMail (nor any IMail addons, as far as I know) will not alter 
attachments in any way.
