IredMail POP3.IMAP.Connection.without.STARTTLS

Since iRedMail-0.8.0, all clients are forced to use IMAPS and POPS (via STARTTLS) for better security by default. If you want to enable POP3/IMAPS without STARTTLS, please update below two parameters in dovecot.conf and restart Dovecot service:

File: dovecot.conf

disable_plaintext_auth=no ssl=yes

Again, it's strongly recommended to use only POP3S/IMAPS for better security.

Reset Root Password Linux Centos

Help! I forgot my root password. How do I log in now?

You can log in using single-user mode and create a new root password.

To enter single-user mode, reboot your computer. If you use the default boot loader, GRUB, you can enter single user mode by performing the following:

1. At the boot loader menu, use the arrow keys to highlight the installation you want to edit and type [A] to enter into append mode.
2. You are presented with a prompt that looks similar to the following:
   

   grub append> ro root=LABEL=/

3. Press the Spacebar once to add a blank space, then add the word single to tell GRUB to boot into single-user Linux mode. The result should look like the following:
   

   ro root=LABEL=/ single

4. Press [Enter] and GRUB will boot single-user Linux mode. After it finishes loading, you will be presented with a shell prompt similar to the following:
   

   sh-2.05b#

5. You can now change the root password by typing
   

   passwd root

   You will be asked to re-type the password for verification. Once you are finished, the password will be changed. You can then reboot by typing reboot at the prompt; then you can log in to root as you normally would.
