Re: [Mailman-Users] access scrubbed attachments of private lists without password?

No. Scrubbed attachments are stored in the list's archive file hierarchy and have to be accessed as anything else in the list's archives. If the archive is private, this requires a password. Also, in general, it seems to me that if a list's archives are private, it would not be a good idea to make attachments to list posts publicly accessible. That depends on the view :-) MIMEDefang (www.mimedefang.org) has a feature to replace attachments with links. The URLs are using a SHA1-based hash of the content of the file. The idea is: if someone gained access to the message, s/he would have access to the attachment, if it had not been removed. The URL is obscured in such a way, that one would need the content of the file to guess the URL to it. No need to protect the attachment any further. Or one could think of the SHA1-based URL as the password to the file. Such URL could look like: https://example.com/mailman/private/list/attachments/20110719/5d9da8c3/sha1hash.pdf or one uses: sha1hash/sanitisedFilename.pdf or something like that. Of course, I do not know how the Mailman password stuff works in detail, so one could place appropriate links into https://host/pipermail/list/ or yet another base path.

[Mailman-Users] Problem with Mailman+Postfix
Hi there.
I´m using Postfix + Dovevot + Mailman on Debian Lenny with ISPConfig3 Setup.
I´ve installed Mailman seperate from ISPConfig via apt-get,
administrating lists works fine but there is one problem: Postfix does
not accept incoming mails to the mailing list.

'postconf -n' is generally more useful than main.cf. It appears the problem is that your list domain is a virtual mailbox domain, but you have no virtual mapping for the list addresses. If that is indeed the problem, you need to add hash:/var/lib/mailman/data/virtual-mailman to virtual_alias_maps in main.cf. You also need to put your list domaian (xyz.net) in POSTFIX_STYLE_VIRTUAL_DOMAINS in mm_cfg.py as in POSTFIX_STYLE_VIRTUAL_DOMAINS = ['xyz.net'] and run Mailman's bin/genaliases to generate virtual-mailman. Also, you should not have hash:/var/lib/mailman/data/aliases because it will cause Postfix's newaliases command to rebuild hash:/var/lib/mailman/data/aliases.db which may adversely affect the owner:group of this file. -- Mark Sapiro m...@msapiro.netThe highway is for gamblers, San Francisco Bay Area, Californiabetter use your sense - B.
