[rt-users] attachments sent via email suddenly have video/x-flv content type

[Jon Tollerton]

  Suddenly some messages coming in via rt-mailgate are ending up with a 
content type of video/x-flv even though the files that are involved are 
.csv or .tiff files.
I unfortunately don't have access to the original messages any more and 
email passes through several MTAs before fetchmail delivers to a 
procmail rule that calls rt-mailgate, so there's lots of points where 
this could be happening.  The strange thing is that so far it appears to 
be spontaneous and nothing has changed in our environment.  It's 
happened from two different sources as well, but not all mail is 
triggering this.  Changing the ContentType of the problem entries in the 
Attachments table corrected these messages, but I'm expecting for this 
to continue to happen when new information comes in.
It doesn't look to me like rt-mailgate does anything with  the content 
type that's passed in the original email other than pass it along to RT, 
but my perl fluency leaves a lot to be desired.  At this point I'm just 
trying to figure out where it makes sense to try to increase logging and 
determine if this sounds at all familiar to anyone?

Thanks,
