    Hello,
    I would like to configure mailbox to send mail to Zulip.
    That app uses [email protected] to manage metadata...
    I try to see in manual and on howtoforge.com if that possible but I didn't find that.
    It seems that a king of wildcard for mailbox name is not possible => alias username.*@example.com
    Do you confirm ?

    Is that +stuff e-mail address on the Zulip side? Or must you create on your ISPConfig server the mailbox [email protected]?
    I'm just guessing here, but if Zulip expects to receive e-mail coming to mailbox [email protected] with +stuff added, they must have configured their e-mail server to accept that +stuff thing in the address. Or maybe in sender address field?
    I assume this tread is about this: https://people.cs.rutgers.edu/~watrous/plus-signs-in-email-addresses.html which I found using Internet Search Engines with
    Code:
    email address with + sign

    Let me explain a bit
    Everything is here :
    https://zulip.com/help/message-a-stream-by-email
    https://zulip.readthedocs.io/en/latest/production/email-gateway.html

    There are 2 options for Zulip :
    - one zulip is managing postfix: I try this first one, but it is not compatible with ispconfig configuration of postfix
    - one is using a postfix conf and screening that inbox: I am trying this second option which is safer (spam, etc...)
    In that second option, zulip is using an existing imap mailbox and scrren it.
    This imap mailbox would be created with ispconfig.

    For example,
    In zulip conf, address to send to is : [email protected], email gateway pattern is "zulipmsg+%[email protected]". These are to be setup in server (docker-compose).
    Moreover, by configuration inside zulip, to send message to "stream1", you define email like [email protected]. This is setup in Zulip app

    Thus, to send email to stream1, you can email to
    -> [email protected]
    -> [email protected] (this will add sender from in message)
    -> there are multiple other possibilities... all are combinations like [email protected]
    All these emails should go to [email protected] mailbox...

    Finally, I need to have email arriving in a same mail box [email protected], messages that could be zulipmsg+%[email protected], this means something like [email protected] or [email protected] or [email protected] (etc)

    In ISPConfig, I need to define multiple alias (many combinations)
    That is why, I was asking for a kind of "regex" to define alias.
    The easiest way to define those multiple alias would be : zulipmsg+%[email protected], this alias, meaning [email protected] or [email protected] or [email protected] (etc)

    If that multiple alias definition doesn't exist, I will predefine few alias !

    My understanding is it does not exist.
    However, there is Email Catchall, see chapter "4.7.1.6 Email Catchall" in ISPConfig 3.1 Manual.
    I think I do not understand what you try to accomplish with Zulip. Maybe it is better if I do not comment anymore on this thread.
