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???

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. :-( Mike -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of R.

Is there a patch? 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. -Scott --- Declude JunkMail: The advanced anti-spam solution for IMail mailservers.
