I am creating webpanel for managing email accounts, aliases etc and wondering how to get "Set vacation" to work.

We are using Dovecot as IMAP-server and Pidgeonhole.

Library that i have checked needs

        $sieved = new \LibSieve\ManageSieve(MANAGESIEVE_HOST, 4190, MANAGESIEVE_USER, MANAGESIEVE_PASS);

Dovecot uses sha512-crypt password schema, so how i can use that library without knowing plain password.

This panel what i am creating, is allowing to admin enable/disable vacation messages for someone.

Unable to use encrypted password for imap and pop3, I can use the encrypted login password with smtp (Postfix), but not with sieve_dir = ~/sieve } protocols = " imap lmtp sieve pop3" service auth  global sieve; sieve_before* user's own sieve or default one if there is no user's sieve; sieve_after* You can place the vacation code into the global/before sieve without knowledge about user's login/pass and it's possible to prevent execution of the any other sieve after vacation code.

Yes but user can set up vacation message from Roundcube webmail and our management panel. Both ways should edit same data. How this can be done without shell-scripting?

The Mobile Application Hacker's Handbook, STRING "string to be encrypted" --bundle-as-obj Got a reply from ServiceBinding): name = "Decrypt Sieve passwords" description = "Decrypt a given password  Dovecot has a very nice Pigeonhole plugin, which provides Sieve scripts (and client-side management of them) to Dovecot. By integrating PGP encryption at this stage, not only do you not have to edit any Postfix configuration (which by itself is an exercise in patience),

You can also use master-password login from select sources to bypass knowing user's password.

passdb {
  driver = static
  # you can also put an encrypted password here
  args = password=verysecretpassword allow_nets=trusted/net

NB, you need to put this in correct place in your passdb. You can also put this inside protocol sieve { }

[PDF] Sieve - People, Even if users encrypt the master secret with a password-derived key [68], users often pick weak passwords [26], giving the master secret weak protection in  Password Schemes¶. Password scheme means the format in which the password is stored in Password databases (passdb).The main reason for choosing a scheme other than PLAIN is to prevent someone with access to the password database (such as a hacker) from stealing users’ passwords and using them to access other services.

Encrypt specific incoming emails using Dovecot and Sieve, Dovecot has a very nice Pigeonhole plugin, which provides Sieve scripts is encrypted, then decrypted with the user's login password (in fact,  Reading encrypted credentials. In order to use these saved encrypted passwords, it will be necessary to read them from the saved file and convert them back to readable form for PowerShell. Reading the password from a file can be done using following command:

If you pass a crypted string as the salt it will use the same salt.

Improved Authentication for Email Encryption and Security, The login password authenticates the user to ProtonMail and is not with this is heavy precomputation via a number field sieve done for a  On FreeBSD, /etc/passwd doesn’t work as a password database because the password field is replaced by a *. /etc/master.passwd can be converted into a format usable by passwd-file. As PAM can access the system-wide credentials on FreeBSD, what follows is generally needed only if the mail accounts are different from the system accounts.
