Running customized version of Mailman 3
by Alan Kelm March 3, 2020

March 3, 2020

Since 2005, our organization has been running a customized version of Mailman 2 with extensions that meet our particular needs. The main novelty is support for /fixed subscription lists/, in which the list members are predetermined (corresponding to a "committee"). Fixed list subscribers are not offered the opportunity to unsubscribe, nor can others add themselves to the list. A further enhancement is /hybrid lists/ which, for example, have both a fixed and opt-in part. (This is implemented as a fixed list residing within an opt-in one in a way which is transparent to users). Our customizations consist of code adjustments (patches) to 23 files. We are considering moving to Mailman 3 and would like to do this in a way which makes it possible to periodically upgrade our installation to the newest Mailman version, without clobbering our customizations. Thus, I do not think that installing via "pip" is the right approach for us. While I'm relatively new to git and GitLab, they seem to be ideally suited to this situation. If I understand the developer documentation correctly, I start out by creating a "fork" and can later "fetch" changes from the master branch and "rebase" to bring them into our branch. I would welcome comments on what we are doing. I also wonder whether others might be interested in support for "fixed lists", if they are done in a way which can be "contributed" back into Mailman. I extend our "thank you" to the developers of Mailman who have provided the robust system which has served us well for 15 years and provides the possibility to extend this into the future. -Alan -- Alan Kelm Manager, Electronic Services Canadian Mathematical Society Tel: +1 (613) 733-2662 ext. 799 Please consider the environment.

ARC issues
by David Krantz March 2, 2020

March 2, 2020

Hi! I have now tested ARC signing of messages a bit more and have found (I think) all settings so that it works in that it generates the signed headers that ARC is. But the signature is not accepted; gmail says "body hash mismatch" and hotmail says "arc=fail (47)". I have set the following settings under the [ARC] section. I have tried both with the sig_headers set as displayed below and with it commented to lean against the defaults. I use the same key and selector as for DKIM-signing with the server's domain. The DKIM-signature is accepted. Is there any known issues with ARC that I should be aware of? I run the latest release of mailman (3.3.0 of core) on Python 3.7.6 and I use postfix as MTA. enabled: yes privkey: <my key path> selector: <my selector> domain: <my server's domain> dmarc: yes dkim: yes authserv_id: <my server's domain> trusted_authserv_ids: <my hosted domains> #sig_headers: From, Sender, Reply-To, Subject, Date, Message-ID, To, Cc, MIME-Version, Content-Type, Content-Transfer-Encoding, Content-ID, Content-Description, Resent-Date, Resent-From, Resent-Sender, Resent-To, Resent-Cc, Resent-Message-ID, In-Reply-To, References, List-Id, List-Help, List-Unsubscribe, List-Subscribe, List-Post, List-Owner, List-Archive I hope that this is something simple that I have forgot. Cheers // David
