Dovecot
Dovecot is an open source IMAP and POP3 email server for Linux/UNIX-like systems, written with security primarily in mind. Dovecot is an excellent choice for both small and large installations. It's fast, simple to set up, requires no special administration and it uses very little memory.
HOWTO: DISABLE:
SSLv3 (POODLE)
sudo nano /etc/dovecot/conf.d/10-ssl.conf ssl_protocols = !SSLv2 !SSLv3 TLSv1.1 TLSv1.2
sudo service dovecot restart
https://www.vultr.com/docs/disabling-sslv3
Standard IMAP Port 143
This will stop Dovecot from opening non secure port 143 and only use secure port 993...
sudo nano /etc/dovecot/dovecot.conf
inet_listener imap {
# address = *
port = 0
}
Or
sudo nano /etc/dovecot/dovecot.conf
protocols = imaps
sudo nano /etc/dovecot/conf.d/10-master.conf
inet_listener imap {
port = 0
}
Then, restart the software...
sudo service dovecot restart sudo /etc/init.d/dovecot restart

Ubuntu Packages / 14.04 + 16.04 + 18.04 + 20.04
On Ubuntu Server
This will install the IMAP daemon for Dovecot, with a self-signed SSL certificate.
sudo aptitude install -v -y dovecot-imapd (type in the fully qualified hostname of your server when prompted, and press return)
Change the configuration files...
/etc/dovecot/dovecot.conf listen = *
/etc/dovecot/conf.d/10-mail.conf mail_location = maildir:~/.maildir
/etc/dovecot/conf.d/10-auth.conf #!include auth-system.conf.ext #!include auth-sql.conf.ext #!include auth-ldap.conf.ext !include auth-passwdfile.conf.ext
Restart dovecot...
service dovecot restart
Let's Encrypt SSL Certificate and Dovecot
Make sure you use the FULLCHAIN file now as the goalposts have moved...
sudo nano /etc/dovecot/conf.d/10-ssl.conf ssl_cert = </etc/letsencrypt/live/domain.co.uk/fullchain.pem ssl_key = </etc/letsencrypt/live/domain.co.uk/privkey.pem sudo systemctl restart dovecot sudo dovecot restart openssl s_client -CAfile /etc/letsencrypt/live/domain.co.uk/fullchain.pem -connect localhost:993 -quiet
SSL Secure Certificate Installation (Paid For)
Switch to root user...
sudo -i
Create directories...
mkdir -p /root/misc/ssl/2016/dovecot
Change to directory...
cd /root/misc/ssl/2016
Create your CSR, send to ssls.com and wait for .zip file back.
Copy your Certificate and the 3 Root Certificates into 1 file...
cat domain_com.crt COMODORSADomainValidationSecureServerCA.crt COMODORSAAddTrustCA.crt AddTrustExternalCARoot.crt > dovecot/dovecot_STAR_domain_com.crt
Copy your Key file into 1 file...
cat domain_com.key > dovecot/dovecot_STAR_domain_com.key
Put the Certificate and Key files into the OpenSSL directories...
cp -av /root/misc/ssl/2016/dovecot/dovecot_STAR_domain_com.crt /etc/ssl/certs/ cp -av /root/misc/ssl/2016/dovecot/dovecot_STAR_domain_com.key /etc/ssl/private/
Edit the Dovecot configuration...
nano /etc/dovecot/conf.d/10-ssl.conf ssl = yes ssl_cert = </etc/ssl/certs/dovecot_STAR_domain_com.crt ssl_key = </etc/ssl/private/dovecot_STAR_domain_com.key
Start the server...
service dovecot restart
SSL Certificate (Self Signed)
openssl req -new -x509 -days 3650 -nodes -out /etc/ssl/certs/dovecot.pem -keyout /etc/ssl/private/dovecot.pem nano /etc/dovecot/conf.d/10-ssl.conf
HOWTO: Restrict To Localhost
sudo nano /etc/dovecot/conf.d/10-master.conf
service imap-login {
inet_listener imap {
address = 127.0.0.1
}
}

HOWTO: Delete All Dovecot Index Files
find /home/user/.maildir/ -type f -name 'dovecot.index*' -print -exec rm -rf {} \;
HOWTO: List User Mailbox Folders
doveadm mailbox list -u user@domain.com
HOWTO: Count User Mailbox Folder Messages
doveadm mailbox status -u user@domain.com messages Drafts
HOWTO: Create Mailbox Folder
doveadm mailbox create -u user@domain.com Fish
http://wiki2.dovecot.org/Tools/Doveadm/Mailbox
HOWTO: Delete Messages
Delete ALL messages...
doveadm expunge -u *@example.com mailbox Trash all
Delete messages older than 2 weeks...
doveadm expunge -u *@example.com mailbox Junk savedbefore 2w
HOWTO: Show Subject and Date Of Messages Containing X
doveadm search -u user@domain.co.uk BODY 'phrase or words to search for' | while read guid uid; do doveadm fetch -u user@domain.co.uk "hdr.subject date.saved" mailbox-guid $guid uid $uid; echo "===================="; done
https://wiki.dovecot.org/Tools/Doveadm/Search
HOWTO: Test Login Credentials Via Command Line
Using the password on the command line is optional. If you leave it off, it will ask you for the password...
doveadm auth test username [password] doveadm auth test emailaddress@domain.com [password]
Testing the encryption method, using the raw database value...
doveadm pw -t '{SHA512-CRYPT}$6$Pzd6eFVy4Q5t$g6m7QypfTA8zw60zjiw08KDjGt7CGDno8gtW8mDn0pIkuzXYA7/7xccbwg.Y.txN32wBe4ny5iOIsafFhOWrf0'
Enter password to verify:
{SHA512-CRYPT}$6$Pzd6eFVy4Q5t$g6m7QypfTA8zw60zjiw08KDjGt7CGDno8gtW8mDn0pIkuzXYA7/7xccbwg.Y.txN32wBe4ny5iOIsafFhOWrf0 (verified)
HOWTO: Move Messages
doveadm move -u email@account DESTINATION mailbox SOURCE search query
e.g.
doveadm move -u user@domain.com 2015 mailbox Sent BEFORE 1-Jan-2016 SINCE 1-Jan-2015
http://wiki2.dovecot.org/Tools/Doveadm/Move
HOWTO: FIX:
dovecot: auth-worker: Fatal: master: service(auth-worker): (core dumped)
For some reason, the PAM module is now broken. After turning on verbose auth logging, the reason was shown...
dovecot: auth-worker(4660): pam(user,192.168.0.40): pam_authenticate() failed: Authentication failure (password mismatch?)
Change the system authentication module to 'shadow' by commenting out the 'pam' option...
nano /etc/dovecot/conf.d/auth-system.conf.ext
#passdb {
#driver = pam
# [session=yes] [setcred=yes] [failure_show_msg=yes] [max_requests=<n>]
# [cache_key=<key>] [<service name>]
#args = dovecot
#}
passdb {
driver = shadow
# [blocking=no]
#args =
}
Error: auth: pam_unix(dovecot:auth): authentication failure
auth: pam_unix(dovecot:auth): check pass; user unknown auth: pam_unix(dovecot:auth): authentication failure;
This is because you are sending login details which the Linux PAM Authentication system cannot understand, because you are using the 'passwd' style of user@domain.com auth login.
To fix, just comment out the 'system-auth' option from the Dovecot configuration file...
sudo nano /etc/dovecot/conf.d/10-auth.conf
#!include auth-system.conf.ext
...and restart Dovecot.
sudo service dovecot restart
AfterLogic WebMail Speed Issue With Large Mailboxes
In static/js/app.js file, locate the following line:
setTimeout(_.bind(this.getAllFolderCounts, this, iAccountId), 2000);
and replace it with:
setTimeout(_.bind(this.executeCheckMail, this, iAccountId), 2000);
Note that app.js file isn't used by default - its minified version app.min.js is used. To change that, add the following item to the array defined in data/settings/config.php file:
'labs.use-app-min-js' => false,
Also, be sure to clear browser cache to apply changes.
The effect of the modification is that list of folders is still obtained, but folder stats are only retrieved for primary folders.

Fetchmail to Dovecot Deliver LDA to Virtual Users
Internet > Fetchmail > Dovecot LDA > Virtual User Maildir
This will show you how to fetch mail from the internet and deliver it to local virtual email users. This is like taking a backup of your IMAP folder. Again, I could not find a single web page on the internet which showed this, so I am writing it down now so that someone else doesn't spend 3 hours trying to figure it out. :-(
http://llg.cubic.org/docs/imapbackup.html
This example is using IMAP and keeping the emails in the internet server, but you could use POP and delete the emails on the server.
Install Fetchmail
emerge fetchmail
Create the Virtual Mail User
useradd -c "Virtual Mail User" -d /home/vmail -U -m vmail passwd vmail
Create the Fetchmail config file for the user 'vmail' (created for the Virtual Users above) which will go and get then deliver the emails.
cd /home/vmail/ touch .fetchmailrc chown vmail:vmail .fetchmailrc chmod 0700 .fetchmailrc nano .fetchmailrc
This is the magic config file. The Dovecot documentation showed dovecot-lda -f $FROM_ENVELOPE -d $DEST_USERNAME but I could not get this variable to work, so hard coded it instead... at least, for now.
/home/vmail/.fetchmailrc
set daemon 300
set logfile /home/vmail/fetchmail.log
set no bouncemail
set postmaster vmail
poll imap.domain.co.uk protocol imap
username "test@domain.org.uk" password "mypassword" fetchall keep
mda "/usr/libexec/dovecot/dovecot-lda -d test@domain.org.uk"
preconnect "date >> /home/vmail/fetchmail.log"
Create the user database file. To generate encrypted passwords, use doveadm:-
doveadm pw -s CRYPT
/etc/dovecot/users
test@domain.org.uk:{PLAIN}password
user@domain.org.uk:{CRYPT}r.oySJdXZSPyE
Your logs will now show something like the following:-
/home/vmail/fetchmail.log fetchmail: 12 messages (11 seen) for test@domain.org.uk at imap.domain.co.uk. fetchmail: reading message test@domain.org.uk@imap.domain.co.uk:12 of 12 (1426 header octets) (10 body octets) not flushed Sat Aug 4 20:49:16 BST 2012

Sieve
This facility consists of 2 parts - the ManageSieve daemon and the Sieve plugins + scripts.
Add the relevant USE flags and re-install the package...
echo "net-mail/dovecot maildir managesieve sieve" >> /etc/portage/package.use emerge -q dovecot
Uncomment the config file line to enable the ManageSieve daemon and port...
nano /etc/dovecot/conf.d/20-managesieve.conf
protocols = $protocols sieve
service managesieve-login {
inet_listener sieve {
port = 4190
}
nano /etc/dovecot/conf.d/15-lda.conf
protocol lda {
# Space separated list of plugins to load (default is global mail_plugins).
mail_plugins = sieve
}
Restart Dovecot...
/etc/init.d/dovecot restart
Check the port is open...
netstat -ntap |grep dovecot tcp 0 0 0.0.0.0:143 0.0.0.0:* LISTEN 32135/dovecot tcp 0 0 0.0.0.0:4190 0.0.0.0:* LISTEN 32135/dovecot

Just create a ~/.procmailrc file in your user's home directory...
DEFAULT=$HOME/.maildir/ LOGFILE=$HOME/procmail.log DELIVER="/usr/libexec/dovecot/deliver" DROPPRIVS="YES" :0 w | $DELIVER
...and then check the server email logs for the entry...
dovecot: lda(sieve): sieve: msgid=<201307151456.r6FEusZI017531@mail.server.com>: sent vacation response to <me@server.com>
Or, a global /etc/procmailrc for the whole server...
# Use maildir-style mailbox in user's home directory DEFAULT=$HOME/.maildir/ # Log actions to file LOGFILE=$HOME/procmail.log # Log synopsis of messages LOGABSTRACT=all # Be verbose VERBOSE=no # Pass to Dovecot for Sieve DELIVER="/usr/libexec/dovecot/deliver" DROPPRIVS="YES" :0 w | $DELIVER
