    Running ISPCFG3 on Debian Wheezy according to Perfect Server with nginx tutorial

    I was just checking my mail logs and found this occurrance where an incoming email triggers a vacation response which is sent with a blank sender and thus bounces:

    Code:

    Ok, I get what you are saying and read those links.
    So this is the safe solution.

    I guess the other party refusing to accept an email without sender is in the minority then and can be safely ignored?
