Disabling sender verification for a single host

Hello,

I tried disabling sender verification for one single IP address, but it doesn't
work as expected:

require verify = sender
hosts = 127.0.1.3

will reject all other mails, while adding an exclamation mark in front of the IP
will reject the mails from this particular IP. What am I missing?

Best regards,

Moritz

You're requiring that all somethings (RCPT smtp commands?)
a) sender-verify
and
b) come from that host

How about inverting your logic -

deny the something when
a) the host isn't that one
and
b) fails to verify-sender

Cheers,
Jeremy

Alright, I wasn't aware that it's a logical and :-)

Just to make sure I don't make a stupid mistake again, would the following be
correct?

deny host = ! 127.0.1.3
! verify = sender

It seems to work at first glance.

Thanks,

Moritz
