MHonArc v2.3.1 is available. Here are the changes from v2.3.0:
Problem: Attachments of the same type get written to the same
Solution: Another my/local gotcha. Note, writing attachments
has been redone so other filters besided mhexternal.pl
can write data to files.
o Support for MHTML. I.e. An HTML document that references data
included as other parts to the mail message, will be converted
so the data will be shown where referenced. Before, all
referenced data was shown at the end of the message.
o Auto-computing the name for attachments no longer caches
data, so performance may decrease when processing MIME
messages. This change is required since multiple filters can
now write data to files and not all to the same directory (a
common utility function now exists for writing data to a file).
Also, it avoids behavioral problems with custom front-ends
that operate on multiple archives in a single process.
o Changes to readmail.pl inorder to support MHTML. Changes
done should help the handling of other multipart/related
