Hi Stefan,

This sounds like a problem I've had using PMMail Windows across a
network.  I found a 'solution' in a message posted a while ago that I
had saved.   I'll paste it below and perhaps you will find that it
helps you too.

The speed problem of PMMail under Win98SE / Win2000 when running from a
mapped network drive is NOT a problem of Windows but one of PMMail:
Every time a message is selected for reading (Preview pane or double
click) PMMail splits header and body of the mail and transforms the
body to rich text format which is then loaded into the viewer. The
implementation of this transformation is very poor, since PMMail
converts line by line instead of reading the mail body in, converting
it in memory and writing it back to disk. This causes heavy network I/O
load! Since 98SE and 2000 cache network file I/O in a different manner
from the other Windows versions, this behaviour leads to trouble. The
solution is to let PMMail create the .rtf intermediate file on the
local disk. Unfortunately it has no setting for it nor does it obey the
standard TMP environment variable. So you have to patch the binary:

Get a Hex editor, close PMMail, search for the string ".\temp\temp.rtf"
in the file pmmailw.exe and replace it by the string "c:\tmp\temp.rtf".
Create the directory c:\tmp, if not already there and start PMMail
again. Enjoy the speed...
