The combination of "usename" and "subdir" works perfectly.

I'll live with the relative insecurity of "usename" compared with "usenameext" for the sanity of my users (a limited and known group).

Thanks again for your help, and sorry again for the unjustified accusation.

I understand now. My apologies.

There is no "missing feature".

The behavior of other email programs is a security risk
since filename specification is only advisory (read the
RFCs). It is this kind of behavior that makes email programs
more susceptible to email viruses/trojans.

If you want to minimize name conflicts, then use the subdir
option to m2h_external::filter, as mentioned in the docs.
Also, usenameext is safer than usename.

It may not be a bug, but it's definitely a "missing feature" given that those attachments are interpreted correctly by every other e-mail program I've tested them with.

Presumably if I use...

<MIMEArgs>
m2h_external::filter; usename
</MIMEArgs>

...the attachments will get saved with their original name, although with the corresponding risk of a name clash.

I'm running MHonArc 2.6.15. I would test this with 2.6.16, but I don't have the time to do the upgrade right now, and there's no mention of anything related to this on the bug list, fixed or otherwise.

It seems that mails sent from Mac Mail on OSX containing binary attachments, most usually .doc and .pdf files, are archived as binXXXXXXXXX.bin instead of docXXXXXXX.doc, pdfXXXXXXXX.pdf etc.

This of course means that the attachment files from the archive cannot be correctly interpreted by the reader unless the file is downloaded manually and renamed.

Such attachments sent as part of mails to the same list from Outlook, Outlook Express or Mozilla Thunderbird on Windows, or Gmail on either Mac or Windows, are stored and named correctly.

Is there a fix for this, perhaps as a separate MIME Filter plug-in. I considered writing a post-processing script to rename such files (and their references in the message HTML) but this is impossible without knowing the original file type, which seems to be lost, if indeed it is obtained correctly in the first place.

Please advise.
