[pmmail-list] PMMAIL 2.20.2380 file corruption (forwards with attachments)

[Ulrich Jakobus]

There is a bug in PMMAIL 2.20.2380 for Windows so that wrong
files get sent as attachment when e-mails are forwarded. Quite
simple to reproduce:

 - create a file c:\x.dat with content "File 1"

 - send an e-mail to yourself with subject "Mail 1" and
   with the file c:\x.dat attached (this file contains "File 1")

 - create a file c:\x.dat with content "File 2" (i.e. overwrite
   or edit existing file)

 - send an e-mail to yourself with subject "Mail 2" and
   with the file c:\x.dat attached (this file contains "File 2")

 - now we have received 2 e-mails with subjects "Mail 1" and "Mail 2",
   both have a file "x.dat" attached, which is of course different
   in content

 - forward the received e-mail with subject "Mail 1" to yourself
   (forward including attached file)

 - forward the received e-mail with subject "Mail 2" to yourself
   (forward including attached file)


BUG: The file "x.dat" which is now attached to both the forwarded
     e-mails has "File 1" attached. The attached file "File 2" of
     Mail 2 got replaced with "File 1" (probably an already existing
     file "x.dat" in the PMMAIL TEMP folder is not overwritten when
     then second e-mail is forwarded).


This is quite a serious bug for me. I created licence files "licence.dat"
for our customers and the licence creation program sent them to me.
I forwarded these licence files to all our customers, and now it turns
out that all of them but the first got the wrong licence file (all got
the licence file intended for the first customer). The only workaround
is to explicitely safe the file from the received e-mail and attach it
again to the e-mail to be forwareded.

Thanks,
