Mailman doesn't have this capability presently but it seems to me that since it already has subscriber confirmation, it should be possible to adapt that sender confirmation. This sender confirmation by email feature is available in L-Soft's LISTSERV, and it is an essential way to avoid fake email. In a post a few years ago Barry said that this feature was going to be in vers. 2.2, but that version never materialized. Will it be in vers. 3? -- \_\ RICHTERS HERBS / / Goodwood, ON, L0C 1A0, Canada \_\ Tel +1.905.640.6677 Fax +1.905.640.6641 /_/ http://www.richters.com

Fake Email
by Hien HUYNH HUU Nov. 11, 2009

Nov. 11, 2009

Dear all, I recognize that mailman can accept a fake sender . Example, I have a maillist with only an email account (xyz(a)abc.com) can send messages to all emails in the list. But , if someone can send a fake "From address" is xyz(a)abc.com, mailman will delivery messages to the list . This is a security problem. Can we prevent this from happening ? Best regards, Huu Hien

Nov. 10, 2009

Hi We have been trying to get mailman working on a fedora 10 installation I can get it working on a internal server but my external server gives the following error. I use webmin which places virtual servers in /home so I had to recompile suexec to work in a different root I suspect this is the problem but do not understand suexec configuration enough to fix the error Internal Server Error The server encountered an internal error or misconfiguration and was unable to complete your request. Please contact the server administrator, root@localhost and inform them of the time the error occurred, and anything you might have done that may have caused the error. More information about this error may be available in the server error log.

Issue with plain text
by Pedro Jacobetty Nov. 10, 2009

Nov. 10, 2009

Hello, I'd like to thank you for your great software, and I'm sorry to bother you with this. I was wondering if you could help me, I'm trying to use mailman mailing list as a way to publish in a wordpress blog. I selected plain text for all subscriptions (such as the blog address) and I thought it would be able to convert a MIME email into plain text. Yet this does not happen: the message reaches the blog as MIME unless it is sent in plain text in the first place. Is there any way I can make mailman convert MIME emails into plain text, so wordpress recognizes the content of the email, and not only its subject, in order to post it? Thanks in advance, Pedro

Quick question
by Support Nov. 10, 2009

Nov. 10, 2009

I'm trying to add a active email link in the non digest footer but having trouble doing so. Is this possible? Basically I manage around 15 lists and want people to be able to opt out of the list by emailing me directly at a certain email address. I can get the email address on there but its not active. I want people to just be able to click it (my email address) and type remove and hit send. Thanks, Joe

Unable To Create Mailman Lists
by Carlos Williams Nov. 10, 2009

Nov. 10, 2009

I just installed Mailman 2.1.9-4 on my Linux mail server and configured it according to the online guide straight from the Mailman site. It appears to be working fine and I get hit the main page via Apache and see the only pubic list available called 'Mailman'. Now I selected the 'Admin Overview Page' and it takes me straight to the 'Admin' page with out any credentials for password or anything. Is this normal Mailman behavior? Should anyone be able to simply hit my Mailman public page and walk right into the 'Admin' page with put any credentials? Secondly - since I am in the 'Admin' page, I then attempt to select the link that says "create a new mailing list" which takes me to a new page for adding all the criteria for the new list I would like to generate. At the very bottom, it has a blank field box for "List creator's (authentication) password:" and I simply have no idea what that is. If I leave it blank or type in the password for the only Mailman list I have called "Mailman", I get an error when creating the new list that says: "Error: You are not authorized to create new mailing lists" Can someone please tell me what I did wrong? Thanks so much! -Carlos

Is There a Hack to Add Author Confirmation of Messages?
by Conrad Richter Nov. 10, 2009

Nov. 10, 2009

I need to move a LISTSERV list to a new listserver. The main hurdle to moving to Mailman is the fact that Mailman lacks the ability for authors to confirm their own messages. The principle is similar to the way Mailman confirms new subscribers, with a web-based message confirmation link emailed to the subscriber. Is there a hack somewhere for adding this confirmation feature for messages? The fact that Mailman already has an email confirmation ability for subscriptions built-in suggests to me that someone, somewhere has figured out a way to use that facility for message confirmation. For those who are interested, we implemented message confirmation on the LISTSERV list as a security measure. We did not want to use moderation because that tends to slow down the discussions and the dissemination of urgent information. But at the same time we wanted a way to prevent non-members from spoofing a list member and getting their offensive postings out to the list. The list is an invitation only list, so once a member is on the list, they are trusted enough to post freely to the list.

Customizing Mailman
by Kim Huff Nov. 10, 2009

Nov. 10, 2009

Hello everyone, My name is Kim Huff and I am new to the list. I have been using Mailman for some time now but I know that I have barely tapped its full potential. I have my own dedicated server and on there I have a few of my clients using the Mailman service. Most of them would like to offer a way for their possibly subscribers the ability to sign-up on line. We want to be very careful about this because we want to make sure people that do not belong to the organization can sign up. So, we would want anyone that signs up to go into a queue and wait to be approved. If there person truly is a part of the group, we will have people that have those records and they can approve or deny a request. The problem is. what URL does one use for to subscribe? Is there a way for me to customize this page? Most of my clients use Joomla so I would need to make sure the subscription page can work within a Joomla page. I do appreciate any help you can provide. Unfortunately, I am kind of in a time crunch so I hope everyone gets this message quickly. Kim
