I have a list which all subscribers can post to. I'm using mailman 2.1.18 on Debian Jessie with exim4. I have full personlisation and verp turned on.
What should I do about DKIM? At the moment I preserve the original poster's DKIM header and my list's MTA also adds DKIM to all outgoing mail. If I set from_is_list to Munge, hotmail users can't reply to the list, even when they hit Reply All (if I try doing Reply All from a hotmail account, I only see the sender's address, not the list address). If it wasn't for this hotmail problem, I'd probably prefer to have a munged from header. If I set from_is_list to No, the hotmail Reply All problem goes away, but now Yahoo-sent email ends up in Yahoo's spam (i.e. if [email protected] sends to [email protected], bob receives the email he just posted in his spam folder, not in his inbox). I'm specifically talking about a yahoo.com.au address (I haven't tried yahoo.com yet). Just to be clear, when from_is_list is No, the DKIM header I'm adding is for the list domain, e.g. if the list is [email protected] then d=example.com in my added DKIM header. Here's an example Authentication-Results added by a gmail subscriber receiving a post from a yahoo.com.au subscriber (names changed): Authentication-Results: mx.google.com; spf=pass (google.com: domain of [email protected] designates x.x.x.x as permitted sender) [email protected]; dkim=pass [email protected]; dmarc=fail (p=NONE dis=NONE) header.from=yahoo.com.au So what is the recommended way of doing this? Should I not bother adding a DKIM header to mailman-sent emails? Should I strip the original DKIM header (REMOVE_DKIM_HEADERS) ? Is there any way I can get hotmail to reply to the list when the From: header is munged? Is munging considered bad form (when not mitigating DMARC reject policies)?
