Hello everyone, I work in a setting where remote logins are usually authenticated with SSH user keypairs, but many target accounts need to have a password set nonetheless (to use with sudo, log in via remote KVM, etc.) and cannot be put under a central user administration like LDAP. Enter a corporate password policy that requires passwords to be complex, different everywhere, and of limited

Hi everyone, I'm running dovecot with quite a lot of users and lots of active imap connections (like 20'000). I'm using different user IDs for users, so I need to have imap {service_count=1} - i.e. I have a lots of imap processes running. Everything works fine, until I reload dovecot configuration. When that happen, every client is forced to relogin in the same time and that

Hello, given a small organization. There are *personal* mailboxes (mailbox per user, incl. subfolders et cetera). The users can share specic folders via the ACL (we call it "other users/", Dovecot calls it "shared" folder. Additionally there are mailboxes Dovecot calls "public" (we use the term "groups/"). They are not associated with a specific account,

If I read this correctly, starttls will fail due to the MITM attack. That is the client knows security has been compromised. Using SSL/TLS, the MITM can use SSL stripping. Since most Postifx conf use "may" for security, the message would go though unencrypted. Correct??? Is there something to enable for perfect forward security with starttls? ? Original Message ?

Hi all, When I use an email client, its purpose is as a window into my Dovecot IMAP, and as a mechanism to reply to and send emails. I don't do filtering or calendaring on my email client (filtering via procmail direct to Dovecot). What email clients are all of you using to look at your IMAP email?

Hello. I am trying to play through the following test scenario about certificate revocation on Ubuntu 18.04, which has OpenSSH of this version: OpenSSH_7.6p1 Ubuntu-4, OpenSSL 1.0.2n? 7 Dec 2017 1. A CA key is created ssh-keygen -t ed25519 -f ca 2. The CA public key is added to ~/.ssh/authorized_keys on some server: cert-authority ssh-ed25519 AAAA...e ca at yoga 3. A user key is created on a
