But in the MUA mailbox one occurrence is always missing in the header.

X-Test-Suspicious:
X-Test-Suspicious: test.ppt
X-Test-Suspicious: test.leotest

Sending just one suspicious attachment always results in an empty
"X-Test-Suspicious:"
What am I doing wrong here?
Trying to add the same header multiple times. Per the ACL docs chapter,
section 24:
"Further header lines may be accumulated during the DATA and MIME ACLs,
after which they are added to the message, again with duplicates suppressed".
- so you've probably found a bug too; that deduplication isn't working right.
Please raise a bug for that.
I suggest appending to your variable in the MIME ACL, generating a
list of dodgy file names seen. Then if non-empty in the DATA ACL, add the
header
there (once).
