Block insecure connections
by Andrea Gabellini 09 Aug '21

09 Aug '21

Hello, I am writing for advice on how to deal with a problem. I have a Dovecot Proxy/Director -> Backend installation, all with version 2.3 Encryption on POP3 / IMAP connections is currently optional. I would like to set it as mandatory but despite the numerous reminders many users have not taken steps to adapt. Setting it as mandatory would mean having too many calls to support. I would therefore like to block the connection to only some of them and slowly reach my target. I can't find how and where to fit in to be able to do such a thing. At first I thought about postlogin, but the user ended up on a proxy and I can't use it. I tried to use the forwarding function on the proxy and postlogin on the backend, but I didn't succeed in the first part. In pseudo code, I would like to do this: if connection is not secured { if user is in my list { block the connection; } } Thanks in advance for any suggestions, Andrea -- __________________________ People says "more memory increases the computerspeed" and they are right: More memory Windows detects, the sooner it crashes. __________________________ TIM San Marino S.p.A.

mail# doveadm pw Enter new password: Retype new password: {CRYPT}$2y$05$oSB6end9V.YumJMzON7lfeOL9N8TXK6jhYqjHOEnPd1NLZ9.QNaTy I thought the default was supposed to be CRAM-MD5.

Pigeonhole v0.5.16 released

Hi, Pigeonhole release for Dovecot v2.3.16. https://pigeonhole.dovecot.org/releases/2.3/dovecot-2.3-pigeonhole-0.5.16.t… <https://pigeonhole.dovecot.org/releases/2.3/dovecot-2.3-pigeonhole-0.5.16.t…> https://pigeonhole.dovecot.org/releases/2.3/dovecot-2.3-pigeonhole-0.5.16.t… <https://pigeonhole.dovecot.org/releases/2.3/dovecot-2.3-pigeonhole-0.5.16.t…> Binary packages in https://repo.dovecot.org/ <https://repo.dovecot.org/> Docker images in https://hub.docker.com/r/dovecot/dovecot <https://hub.docker.com/r/dovecot/dovecot> * .dovecot.sieve.log file now includes year in the header. * Change Sieve script result execution to delay definitive action execution to the end of a successful Sieve script execution session. This is part of an effort to solve problems with the Sieve duplicate test. As a side-effect, some rare temporary-error cases yield different results, in which partial failure is more likely.

Dovecot Debian repo instructions need updating
by Laura Smith 05 Aug '21

05 Aug '21

Re: https://doc.dovecot.org/installation_guide/dovecot_community_repositories/d… The instructions need updating for two reasons: 1) Keep up to date with Debian releases (https://wiki.debian.org/DebianReleases), i.e. remove reference to 8.0 "Jessie" and replace with 10.0 "Buster". 2) The instructions presented for key handling are not inline with Debian best-practices. As per https://wiki.debian.org/DebianRepository/UseThirdParty: "The key MUST be downloaded over a secure mechanism like HTTPS to a location only writable by root, which SHOULD be /usr/share/keyrings. The key MUST NOT be placed in /etc/apt/trusted.gpg.d or loaded by apt-key add. A sources.list entry SHOULD have the signed-by option set. The signed-by entry MUST point to a file, and not a fingerprint."

There isn't much documentation on quota_grace. How would you disable quota grace? quota_grace = 0 quota_grace = 0% quota_grace = 0m quota_grace = -1 Assuming "0" isn't an "unlimited" setting?

Is this a valid quota rule? *:storage=0,messages=0 Or do I need to make them two separate rules? Joseph D Wagner

Timo - is the v2.3.15 GCC limitation really necessarily or it's just a bug?
by Mart Pirita 02 Aug '21

02 Aug '21

Hello. So far I have successfully built Dovecot until v2.3.14 on Centos 4-6 (yes I know, they are old, but as they are remote servers, distros can't upgraded), and sometimes I have also met compilation issues, but after highlighting them, Timo have fixed the code. Found from similar thread (Dovecot 2.3.15 compilation fails https://dovecot.org/list/dovecot/2021-June/122412.html ) that new GCC is needed. However I can't find such requirement in v2.3.15 change log. As seems that I'm not the only one with compilation issues, then @Timo - can You please fix the code so that also v2.3.15 can compiled on older distros?
