[Mailman-Users] a question about content-filtering

[liste yoneticisi]

I configured the list and default values accourding to the following
values.

I filled the filter_filename_extensions and pass_filename_extensions
parameters for filtering attachments.

the values are listed below:
filter_filename_extensions = """exe
bat
cmd
com
pif
scr
vbs
cpl"""

pass_filename_extensions = """doc
xls
xml
xlw
ppt
pps
pdf
php
gz
gif
jpg
jpeg
bmp
png
htm
html
txt
rtf
rar
zip"""

But i have a problem, if someone sends a document with file name qwe.JPG
mailman doesn't send the attachment.
I couldn't add the Capital letter extensions. Mailman converts them to
lower letter.

Do you have any advise about it?
