I've actually been thinking about it almost since the beginning. It's just been annoying waste of space on my screen. And more importantly nowadays it's also breaking DKIM/DMARC signatures. So if somebody still uses Subject-based filtering it's about time to switch to List-ID header based filtering now.

Another thing I'm wondering about is if I should allow text/html parts, because removing them will also break the DKIM signatures. Or mainly I'd like to allow only multipart/alternative with text/plain + text/html, but I don't think I can configure Mailman to support that.

Hi,

Just wanted to ask what happened to "[Dovecot]" when I saw this mail. Could you tell me how to find the List_ID ? I looked at the raw mail, but I didn't find it :

You could use that header (which actually should better be gone because reply-to munging considered harmful) or some other header field with "dovecot" somewhere.

FWIW text/html is actually overrated and - essentially - superfluous. Additionally it makes it even easier to fool the average user.

I'm using Thunderbird as MUA. I'll look at the messages on the server.

Never noticed before there was something missing.

I looked at some messages on the server. Not trace of those List-lines. I think I will get in touch with Watchguard to see if they remove those lines.

I subscribed to dovecot with a home-account. There I do have those RFC2919 lines. I also just "whitelisted" the dovecot-list on my Watchguard. I'll see if that changes anything. But I also filed a "bug-report" with Watchguard concerning this. You would think such a company should know better.

not uncommon, i saw anti-virus software mangle http traffic by spit random bytes before the http headers leading to ask the browser where to save the php-file

Cisco routers by default mangle DNS traffic, break zone transfers or even put befor all CNAME blocks a $TTL 0 line never appeared on the master until you disable DNS ALG for UDP and TCP

the bigger the company the more breakage

and that is why i said "you have crap on your side" what for whatever reason you took as a personal attack leaded to lure all the trolls out of their holes and react to a out-of-context quote

I believe that Cisco equipment will do such things, but I doubt it's the routers. Unless you plug a firewall card in.

A bit back on-topic here:

My impression is that Outlook 2013 will move mails from one (Dovecot) folder to the other by downloading the mail, messing up the headers and uploading again. This will break the antispam plugin, of course.

Can anyone confirm?

off-topic but as response "i thought they know better"

any bigger Cisco router i saw the last 8 years and even some smaller ones without rack-mount did this as default if NAT is enabled until you force the two commands below

the reason likely is that if you have a public DNS server you are asking from the LAN responding with a public address the Cisco translates the repsonse to the NAT-mapping instead just allow the public IP from the LAN, but that's no valid reason to mangle outgoing DNS traffic

additionally that may become "funny" if in the future DNSSEC is used

"no ip nat service alg udp dns" "no ip nat service alg tcp dns"

the UDP ALG leads to silently supress answers of PTR's with public IP's to the WAN, larger UDP responses (EDNS) times out as well as zone-transfers

the TCP ALG leads to a AFXR zone transfer looks like below while the master has only one TTL line with 86400 on top of the zone file, in that case only CNAMES are mangelded and after type the commands above all is fine

rhsoft.net. 86400 IN A 91.118.73.4 **.rhsoft.net. 0 IN CNAME **.rhsoft.net. **.rhsoft.net. 0 IN CNAME **.rhsoft.net. ................................ testserver.rhsoft.net. 86400 IN A 84.113.92.77 **.rhsoft.net. 0 IN CNAME **.rhsoft.net.

Actually you're both incorrect - this isn't a PIX/ASA specific thing and it does work that way on IOS routers in certain configurations. A Cisco IOS router (800/1800/1900 etc) running recent code will do this if you have a PAT rule translating port 53 from outside to inside.

This isn't a configuration that is that common, and it is annoying when you run into it, but it's not something you can have happen "by accident" since you have to specifically configure port 53 to be NATted in to observe this behaviour. It's also easy to turn off (TBH I don't know why it's not off by default, but that's a separate matter).

It doesn't impact normal outbound/dynamic NAT which is what most people use.

I haven't tried 1:1 static NATs so can't verify if it works that way in that situation, though.

we are running 1:1 static NAT and it is enabled by default in that situation that's what i am talking the whole time, nobody does single port-forwardings in a server environment

and *yes* you can have happen this "by accident" simply by have non Cisco hardware before with the same 1:1 NAT and then get a Cisco device due switch from bundeled DSL lines to glasfiber

Guys,

I think you were a bit harsh on Reindl.

It is my opinion that he is a productive member of this list and his views are valuable.

He just uses a bit stronger language. Something that I do sometimes.

I don't think he wanted to be rude with someone.

Just my opinion,

besides that the envelope sender is "dovecot-bounces@dovecot.org" and To/Cc always "dovecot@dovecot.org" it's easy to filter that with Sieve, subject based filters are broken anyways

Because you have crap software.... ;)

It's not caused by Thunderbird itself (it might be an add-on!)

I'm reading with thunderbird too, and in the headers of the firts post in this hread i see: List-Id: Dovecot Mailing List List-Unsubscribe: http://dovecot.org/cgi-bin/mailman/options/dovecot, mailto:dovecot-request@dovecot.org?subject=unsubscribe List-Archive: http://dovecot.org/pipermail/dovecot/ List-Post: mailto:dovecot@dovecot.org List-Help: mailto:dovecot-request@dovecot.org?subject=help List-Subscribe: http://dovecot.org/cgi-bin/mailman/listinfo/dovecot, mailto:dovecot-request@dovecot.org?subject=subscribe Errors-To: dovecot-bounces@dovecot.org Sender: "dovecot" dovecot-bounces@dovecot.org

are you a piece of software or why do you take "crap software" personally against yourself?

you should have read the rest of my answer something "smart" mainpulates messages you receive this may become a *serious* problem in case of signed messages

this is most likely also the reason you hit reply all because removing the list-headers makes the "reply-to-list" button in thunderbird non-functional

if somebody wants to feel absued he will find always a reason - calling software stripping headers out of mails is not a good one to feel so

so shut up until you can't distinguish between firt name and last name, write the last name even wrong and especially in case i abused nobody

Don't bother paying too much attention, Harald has been quite the primadonna ever since I joined this list. Pretty sure he's one of those fellows who are doing the 'grumpy curmudgeon' on the Internet but then turn out to be rather quiet/shy guys in real life. ;-)

If he bothers you, a suggestion to make your life simpler. Set up a filter to simply delete any messages from him before they get to your inbox.

Notice that most regulars, myself included, never reply to him. That is because we do not even see his messages except in someone else's reply to him. It really improves the quality, value and enjoyment of the list. Life is too short to put up with someone who is abrasive, obnoxious and rarely contributes anything helpful.

and that is why people like you should simply *shut up* instead react on a *one line quote* stripped all helpful informations including the complete context

so you see *one line* of a long reply because you filter out anything else: so *shut up at all*

Yes you can, well sort of - see below, but note that in addition to content filtering, the addition of msg_footer will probably break DKIM signatures.

If you put the following in pass_mime_types

multipart/alternative text/plain text/html

and set both collapse_alternatives and convert_html_to_plaintext to No, multipart messages which are not multipart/mixed (e.g., multipart/mixed, multipart/related and multipart/signed) will be handled according to filter_action. Messages which are multipart/alternative with only text/plain and text/html alternatives will be passed unchanged by content filtering as will single part messages of type text/plain or text/html.

Potential problems with this are:

you may not want single part text/html on the list.
some people sign their posts.

Because of 2), you need to add multipart/signed and application/pgp-signature to pass_mime_types, but that complicates the content filtering scenario because now a message with a structure like

multipart/signed text/plain application/pgp-signature image/jpeg

will be accepted by the list with the image/jpeg part removed rather than handled according to filter_action.
