Description Luca Lesinigo 2014-07-03 07:50:59 UTC

This nice guy did wrote the "onchange" patch for vpopmail:
  https://qmail.jms1.net/vpopmail/
His patch was accepted upstream some years ago in vpopmail-5.4.18.

Gentoo currently has vpopmail-5.4.33 stable and 5.4.33-r1 unstable; they're both based off the vpopmail-5.4.33.tar.gz source tarball which has the patch included and a nice doc/README.onchange file explaining it.

The patch is enabled by passing --enable-onchange-script to the configure script and it looks for a ~vpopmail/etc/onchange script to execute when anything changes (new account, modified account, etc...). Just enabling the patch without putting a script there should not change anything for current users, but it could be made a USE flag to allow people to choose.

[offtopic: while you're at it, --enable-domainquotas would be useful too]

The onchange hook would be of great use in many areas. Our use case could be one of the most common I guess: keep an update list of valid RCPT TO addresses to use on separate Mail eXchanger hosts to refuse mail for unknown users, thus avoiding to generate backscatter mails.

Reproducible: Always

Steps to Reproduce:
1. install vpopmail
2. try to keep an update list of valid RCPT TO addresses
3. fail :/


Expected Results:  
put a script in ~vpopmail/etc/onchange and get it called every time something changes.

    net-mail/vpopmail: enable onchange script
    
    If there is no script put there by the user then this simply does nothing as
    before.
    
    This also drops the dependency on postgresql[server] as I see no reason that
    this would not work with a remote server.
