[Dovecot] can't download attachment from the wiki

[Andrew Schulman]

Hi.  At http://wiki.dovecot.org/ManageSieve#line-229 , I want to download
the patch that's supposed to fix two problems in Avelsieve.  Unfortunately,
when I click on the link to the patch, I always get an error message:

You are not allowed to do AttachFile on this page.

Annoying.  I've created an account and logged in, but still no joy.  Can
anyone suggest how or where else I can get that patch?

Thanks,
Andrew.
