Hey Guy,
|
|
|
|
First, thanks a bunch for writing Mail::Ezmlm, it's quite useful. :-)
|
|
|
|
I've used it to write a CGI interface to Ezmlm for a client. It's not a
|
|
very complex thing, it just creates a web page where the client logs in
|
|
and then has the choice to list the subscribers for a list, batch add a
|
|
list of subscribers, or mass delete a list.
|
|
|
|
It's posted here if you're interested in seeing it:
|
|
https://mail.cadillac.net/ezmlm.cgi
|
|
|
|
You can log in using the domain "example.com" and the password
|
|
"guyrucus".
|
|
|
|
Anyhow, the only problem I've had with Mail::Ezmlm is that when I run
|
|
my script suid as the user that owns the mailing list, mod_perl whines
|
|
about the data because it's tainted. So, I've made a few minor
|
|
alterations to untaint the data. My approach is rather basic and could
|
|
be improved upon but it works quite well and is slightly more secure
|
|
than what's being used at present. I'd appreciate if you'd review the
|
|
patch and apply it or something similar which achieves the same result.
|
|
|
|
The patch is against v 1.9 of Mail::Ezmlm.
