I'm running AsyncOS ver. 6.1.0-304 and seem to be running into an odd problem. I am currently not running any type of content filtering and yet I have a specific problem that for whatever reason when a certain vendor of ours sends an email with a .CSV file attached, the attachment is embedded into the email message instead of showing up as an attachment.
The same email that goes to a gmail.com address shows up fine and when I forward that message into my organization the attachment shows up. At this point I'm thinking that it's some type of incompatibility between my Ironport and their mail server a Lotus Domino Release 7.0.1 server.
Has anyone else out there ever seen anything like this?
