[Bug 701558] [NEW] Content filtering leaves a single sub-part in a multipart message.
by Mark Sapiro 09 Jun '17

Public bug reported: If the original message is multipart but not multipart/alternative and content filtering removes all but one part, the message is left as a multipart message with only the one sub-part instead of being recast as just the sub-part.

[Bug 576675] [NEW] Content filtering fails to collapse alternatives.
by Mark Sapiro 09 Jun '17

Public bug reported: Collapsing multipart/alternative parts to just the first alternative only works if the message itself is multipart/alternative, or the multipart/alternative part is at the first sub-level. For example, given this structure: multipart/mixed | multipart/related | | multipart/alternative | | | text/plain | | | text/html | | image/jpeg | application/msword The multipart/alternative part will not be collapsed. ** Affects: mailman Importance: Medium Assignee: Mark Sapiro (msapiro) Status: In Progress ** Changed in: mailman Importance: Undecided => Medium ** Changed in: mailman Status: New => In Progress ** Changed in: mailman Milestone: None => 2.1.14 ** Changed in: mailman Assignee: (unassigned) => Mark Sapiro (msapiro) -- Content filtering fails to collapse alternatives. https://bugs.launchpad.net/bugs/576675 You received this bug notification because you are a member of Mailman Coders, which is subscribed to GNU Mailman.

[Bug 1539384] [NEW] Non-blocking DMARC mitigations should also be done for p=none
by Jakob Bohm 29 Dec '16

29 Dec '16

Public bug reported: If you read the DMARC informational RFC (no longer just a draft), you will see that there are 3 possible policies a mail domain (of a poster) can set p=reject All recipients should reject/drop mails with From: ...<at ourdomain> that have neither DKIM not SPF pass for our ourdomain. Send automatic reports of this to our postmaster at the specified rua address. p=quarantine All recipient spam filters should penalize ditto. Send the same automatic reports. p=none Recipients should act as if this policy was not there, but send the automatic reports so we can decide if our policy needs fine tuning before switching to a tougher p value. Currently Mailman 2.1.20+ has code that applies reasonable adjustments to avoid failures with posters from p=reject domains (such as Yahoo). Mailman 2.1.20+ also has an option to do the same for p=quarantine. But when a domain is set to p=none because the postmaster is trying to figure out what will break if he/she/they turn on quarantine, Mailman will continue sending mail in a way which causes all the backscatter reports from everybody except the list owner. As a postmaster I find this very annoying as it makes it hard to find actual problems in the flurry of backscatter noise from making even a few posts to a single Mailman list. Especially annoying is reports that some servers received mails with failed DKIM from a 4th party IP, as it is impossible to tell if those 4th parties were forwarding mails that were broken by Mailman munging the Subject header or were handling mails of some other kind needing a different correction. I would therefore suggest the following change to the 2.1 branch (since 3.x is still not in a usable state): * If dmarc_moderation_action is set to a value other than Reject or Discard, the specified mitigation should be applied to domains with any valid DMARC policy, not just reject. The effect of this would be: + List admins need to do nothing extra, since this works with the existing Mailman settings. + Domains that use p=none with a user posting to a list with action other than Reject/Discard will see the true effects that setting p=reject would have, and their users will see any change in the Mailing list behavior and be able to complain to the local postmaster before the domain goes to p=reject. Which is exactly the intended purpose of p=none. + Domains that use p=none with a user posting to a list with action set to Reject/Discard will receive a flurry of error reports reflecting how badly things will break if they go to p=reject, but the users will not loose their ability to post (because the reject/discard action is not applied to domains with p=none). Again this is consistent with the intended purpose of p=none. + Domains that use p=quarantine with a user posting to a list that has not set dmarc_quarantine_moderation_action will see the same effects as domains that use p=none (see above). + Domains that use p=quarantine with a user posting to a list that has set dmarc_quarantine_moderation_action will see the same behavior as for the current 2.1.20 code. + Domains that use p=reject will see the same behavior as for the current 2.1.20 code. ** Affects: mailman Importance: Undecided Status: New ** Tags: dmarc -- You received this bug notification because you are a member of Mailman Coders, which is subscribed to GNU Mailman. https://bugs.launchpad.net/bugs/1539384 Title: Non-blocking DMARC mitigations should also be done for p=none To manage notifications about this bug go to: https://bugs.launchpad.net/mailman/+bug/1539384/+subscriptions
