I have an IMail server that all of a sudden started stripping outbound
PDF attachments. There is nothing configured in IMail that I can find
to cause this. No spam filtering is taking place and any attachment
filtering is for files like EXE, SYS, COM, BAT, etc. PDF extensions are
not in the attachment list at all. I cannot find any reason at all for
this bizarre behavior all of a sudden.
It's throwing this kind of thing in the header of the outbound message:
X-IMAIL-ATTACHMENT-BLOCKED: (117201b200001457, Filename, Strip, ATS 1
