Notify user when mail arrives

    Is it possible to send an eMail like "You´ve got mail" to a specific user if a mail arrives in a special mailbox?

    I tried to find a solution with Sieve, but it semms that is only possible to forward the mail. But that is not desirable. Only a notification is necessary.

    Until now, we solved this with the Thunderbird plugin "Mail Alert" - but this is no longer actively developed and no longer works with new TB versions.

    Does anyone know advice for this task? TIA

    yes, in the mailbox settings in ispconfig, for the mailbox you want someone alerted about, put that persons email address in the 'send copy to' field.
    not only will they get an email about it, it'll include all the original emails contents as well, so they don't even need to login to this special mailbox to see what it's all about. ;)

    Thanks for your input!

    But unfortunately, that is exactly what is not desired. The person who is to be notified must not know what is in the mail.

    He should only know that there is a new mail in the mailbox.

    Thank you @pyte - thats exactly what I need!

    Did some tests and it works great. One final question for activating the extentions:

    Its not possible to use the line
    require ["enotify", "fileinto", "variables", "envelope"];
    in the "Custom Rules"-Section of ispconfig/mail/mail box/specialmailbox, because it has to be defined in the first line of the sieve-file.

    So I found out, thats a good place to insert the needed extenion is /var/vmail/
    But in this .ispconfig-before.sieve-file is the warning
    # This sieve script is generated by ISPConfig, any changes made will be overwritten.
    # You can create and activate a per-user sieve script (manually or via managesieve),
    # which will execute after this.
    Where is the best place to bring in my new
    require ["fileinto", "mailbox", "regex", "date", "relational", "vacation", "imap4flags", "envelope", "subaddress", "copy", "reject", "enotify", "variables"];

    Thanks for answers?

    Run these commands on your server as root user:

    cp -pf /usr/local/ispconfig/server/conf/sieve_filter.master /usr/local/ispconfig/server/conf-custom/sieve_filter.master
    nano /usr/local/ispconfig/server/conf-custom/sieve_filter.master
    Adjust the file as needed and save it.

    Then edit something in the custom filter rules field and save to get the .sieve file of the mailbox created from scratch based on the new master file.

    Thanks Til - nearly what I expected. I expected that I have to use /usr/local/ispconfig/server/conf-custom/mail/
    What about this subdirectory?

    This is for email templates, not filters or config files. Take a look at /usr/local/ispconfig/server/conf/mail/ to see which files are there.

    Wouldn't that overwrite all mailboxes when a sync would take place and not just the desired one?

    If your server has Roundcube installed have you tried the Managesieve plugin?
    That too has an option to send a notification on receiving an email and let's you set different kind of options like notification text and notification sender address for example.

    @remkoh - thank you for that hint about Managesieve, I didnt noticed about that. Lets have a look.

    In the meantime I set a custom rule in the email-section of ispconfig.
        # :matches is used to get the address from the From header
        if address :matches :all "from" "*" {
            set "from_addr" "${1}";
        notify :message "eMail eingetroffen von ${from_addr}"
                        "mailto:[email protected]";
    This works like a charm and it do exactly what I want.

    Managesieve will create a rule in the background similar to what you've created manually as custom rule.
    So the result will be the same. Difference is it's gui configurable.

    But you should be aware that using managesieve can cause conflicts with ISPConfig and settings you do with managesieve might get removed when you use ISPConfig to set mailbox rules, use autoresponder etc.

    My experience is they work side by side. Not sure how it's prioritized though.

    Although I suppose configuring the same thing in two different ways might give you conflicts.
    But that's an user error in my opinion.
