    Default restricting sender

    Dear All,

    I have just moved to zimbra OSE and would like to implement a feature for restricting senders.

    for example the user should be able to send at a time only to say 15 recipients or 20 ( a configurable no.) and if more the mail should not be sent with a warning message to the sender.

    also other configurable things like max emails a user can send a day , and the time between subsequent emails

    actually I use to use sendmail + squirrelmail web client which had a restrict sender pluggin and one could configure all the above things

    I did Google around with no much luck

    Highly would appreciate if someone could help and advice me


    regards

    benedict

    The default value of the max number of recipients is set to 100.
    To change this value you have to modify the 'smtpd_recipient_limit' attribute:
    Code:
    su  zimbra
    postconf -e 'smtpd_recipient_limit = valore'
    postfix reload
    also other configurable things like max emails a user can send a day , and the time between subsequent emails
    Maybe you can look at the PolicyD integrated with zimbra 7.
    With the quota module enabled, you can activate a message counter based on sender; for more info:
