Default sieve rules for new users

[mejay]

Is there a way that I can have certain sieve rules automatically created for new users? They should be able to see them and edit/delete them, but I want them to show up and be active automatically for new accounts.

Hello,

Sieve rules are email account specific, i.e. they individual for every single default accounts. Unless you create global rules.
Individual rules are saved to

- /home/<USERNAME>/imap/<DOMAIN>/<USER>/sieve/managesieve.sieve

Create the file and populate it with instructions using POST hooks:

This is the way I've done it. Here's my current script, to create a filter to put suspected spam into the Junk folder. Might be useful for someone.

# cat /usr/local/directadmin/scripts/custom/email_create_post/spam_sieve_filter.sh
#!/bin/bash

# Available environment variables, as documented in
# <https://docs.directadmin.com/developer/hooks/email.html#email-create-pre-post-sh>:
#
# username: directadmin account
# user: email account name
# domain: domain where virtual email is created
# passwd: password of account
# passwd_is_crypted(0|1): if set, passwd is encrypted
# quota: disk quota in Mib for email account (0 is unlimited)
# limit: daily send limit (0 is unlimited)

# Make sure the environment variables we use have values that make sense.
if [ "${username}" = "" -o "${domain}" = "" -o "${user}" = "" ]; then
    echo "Error: Either \$username, \$domain, or \$user is empty. Aborting." >&2
    exit 1
fi

if [ ! -d "/home/${username}" ]; then
    echo "Error: Directory /home/${username} does not exist. Aborting." >&2
    exit 1
fi

if [ ! -d "/home/${username}/imap/${domain}" ]; then
    echo "Error: Directory /home/${username}/imap/${domain} does not exist. Aborting." >&2
    exit 1
fi

if [ ! -d "/home/${username}/imap/${domain}/${user}" ]; then
    echo "Error: Directory /home/${username}/imap/${domain}/${user} does not exist. Aborting." >&2
    exit 1
fi

# The path of the email account, which we know is valid.
email_account_dir="/home/${username}/imap/${domain}/${user}"

# Check if the managesieve.sieve file already exist. This would not usually be
# the case when the script is run as a DirectAdmin hook, but could be the case,
# if this script is run independently. If the file already exist, we don't want
# to overwrite it.
if [ -f "${email_account_dir}/sieve/managesieve.sieve" ]; then
    echo "Error: ${email_account_dir}/sieve/managesieve.sieve already exists. Will not overwrite. Aborting." >&2
    exit 1
fi

# The contents of the sieve filter we're creating
spam_filter='require ["fileinto"];
# rule:[Spam]
if allof (header :contains "x-spam-flag" "YES")
{
    fileinto "Junk";
    stop;
}'

# Set up the directories, filter, symlink, and fix ownership/permissions
mkdir -p "${email_account_dir}/sieve/tmp"

echo "${spam_filter}" > "${email_account_dir}/sieve/managesieve.sieve"

if [ ! -L "${email_account_dir}/.dovecot.sieve" ]; then
    ln -sr "${email_account_dir}/sieve/managesieve.sieve" "${email_account_dir}/.dovecot.sieve"
fi

chown -hR $username:mail \
    "${email_account_dir}/sieve" \
    "${email_account_dir}/.dovecot.sieve"

chmod 0700 \
    "${email_account_dir}/sieve" \
    "${email_account_dir}/sieve/tmp"

chmod 0600 \
    "${email_account_dir}/sieve/managesieve.sieve"

That looks like it should work perfect, thank you!
