textmail filters a mail message or mbox file, replacing MS Word, MS
Excel, HTML, RTF and PDF attachments with the plain text contained therein.
By default, the following attachments are also deleted: image, audio, video,
and MS Windows executables. MS
winmail.dat attachments are
replaced by any attachments contained therein which are then replaced by
text or deleted in the same fashion. Any of these actions can be suppressed
with command line options. Mail headers can also be selectively deleted.
This is useful for increasing the accessibility of mail messages (by reducing their dependence on proprietary file formats), for dramatically reducing their size (and the time it takes to download them and the time it takes to read them), and for dramatically reducing the risk of mail-borne viruses). Its intended use is to reduce the size of a personal email archive but it could also be useful as a pre-processor for mailing lists. This is more friendly than a strict "No Attachments" or "No HTML" mailing list policy.
textmail is freely available under the terms of the GNU General Public License, either version 2 of the License, or (at your option) any later version.
Translation to plain text
The following documents are translated into plain text: MS Word, MS Excel, RTF, HTML and PDF.
Deletion of large attachments
Image, audio and video attachments are deleted by default.
Elimination of mail-borne viruses
MS Windows executable attachments are deleted by default.
MS TNEF (i.e.
winmail.dat) attachments are unpacked
by default and replaced by any attachments contained therein which
are then replaced by text or deleted as required.
Deletion of binary attachments
application/octet-stream or all
application/* attachments can be deleted.
Deletion of unwanted mail headers
Headers can be deleted selectively by providing prefixes
If it is impossible to translate an attachment, you have the choice of leaving the original attachment intact, or of discarding it in favour of the empty text translation.
