Since sending to the alias will send to a, b and c, just define the filter on one mailbox only instead of making it global I guess.

I am curious to know how did you define the filter on an alias in the first place ? is it a filter defined globaly in dovecot ? I don't see how it can be defined in any individual mailbox. Can you show the dovecot/sieve configuration to achieve this ?

Hi Yassine,

Thanks for the effort, unfortunately, we cannot turn it into an actual mailbox, this is a long story that I don't want to include here. but it would not be a valid option in our environment. Any other ideas

Is it possible to do it with vacation? Is there another auto responder or plugin that can achieve this? How do ticketing systems handle this?

Thanks

Monis

Hi,

We have an alias group named xyz@example.com, this alias group has 3 actual users a@example.com, b@example.com and c@example.com

We set vacation rule on the generic sieve rule, the problem is that 3 responses are sent to the original sender. (obviously because the rule is being executed with each user in the alias group)

Is it possible to set auto response only once, we tried the ( :days 1) option but still all 3 respond back.

How can such a setup be achieved. (Single auto response to an alias group)

Hello Monis,

As a workaround, you can turn xyz@example.com into an actual mailbox and give a@example.com, b@example.com and c@example.com read-only shared folder access.

Yassine.

As a request for comments and improvements, here's a my script to share folders via acl files and symlinks (dovecot must be configured accordingly) :

root@messagerie[10.10.10.19] /usr/local/scripts/mail # cat sharemailbox.single
#!/bin/bash

function create_link {
    l_src=$1
    l_dst=$2
    l_maildir=$3
    t_maildir=$(echo "$3" | tr . ․)
    t_dst="$l_dst"/.shared."$t_maildir"
    echo pointing "$t_dst" to "$l_src"
    echo ln -s "$l_src/" "$t_dst" 
    ln -s "$l_src/" "$t_dst" 

}


function verifier_email {
    l_email=$1
    if ! searchmailbox.strict.sql $l_email > /dev/null
    then
        echo "l'utilisateur $l_email n'a pas pu être trouvé dans la base de données." >&2
        return 1
    fi
    return 0
}

function set_acl {
    l_maildir=$1
    l_email=$2
    echo "giving $l_email access to $l_maildir"
    if [ ! -d $l_maildir ]
    then
        #.Sent isn't there yet.
        return
    fi
    acl_file="$l_maildir/dovecot-acl"
    echo "echo user=$l_email lr >> $acl_file"
    echo user="$l_email" lr >> "$acl_file"
    chown vmail:vmail "$acl_file"
}


if [ "$#" -lt 2 ]
then
    echo "usage : $0 partage@domain.com user1@domain.com user2@domain.com ... "
    exit 1
fi

email="$1"
inbox="${email%@*}"
domain="${email#*@}"
src="/var/vmail/$domain/$inbox"
if ! verifier_email "$email"
then
    echo "exit at 1"
    exit 1
fi


shift
for share_email in $@
do
    if ! verifier_email $share_email
    then
        continue
    fi
    share_inbox="${share_email%@*}"
    share_domain="${share_email#*@}"
    share_maildir=/var/vmail/"$share_domain"/"$share_inbox"
    #echo grep "$share_email" "$src"/dovecot-acl
    if grep "$share_email" "$src"/dovecot-acl > /dev/null 2>&1
    then
        # then is executed when exit status is 0
        # exist status is 0 when there is a match
        echo "$share_email" has already access to "$email"
    else
        set_acl $src $share_email
        create_link $src $share_maildir $inbox
    fi
done
root@messagerie[10.10.10.19] /usr/local/scripts/mail #
