I am pretty new to ESVA and I managed to do a successful installation and getting it running. The ESVA server is setup to sit between internet and Exchange server. Every now and then I get complain from users that someone from outside is trying to send them an email with pdf and quark files as attachments and they are coming is as 0k (zero K) files. I can see in the maillog that file coming in are about 9mb and I allow up to 15mb inbound and the message goes to Mailscanner then from there I don't know what happens. So my question is what could be causing this and where should I look for answers in ESVA? Thank for all your help in advance.
