Hi,

assuming you use the script here (as guessed by hippo), try to switch to the reply by NateTut and use his variant. There the filename is set by the line:

my $FileName = sprintf("%04d_Message.txt", $num);
[download]

You want to change this, e.g. by putting the subject in front

my $FileName = $subdir ."_". sprintf("%04d_Message.txt", $num);
[download]

If you want to access the received-date of the mail, you can have a look at $doc->{received}->[0]. This string contains the date/time (and more, so you have to extract it).

HTH, Rata
