Forwarding and IP Ranges

Post by kevin@wine.co.za » 2013-09-12 15:14

Hi guys : I am busy trying to secure my mailserver - having been hacked through an IMAP account last night ...

I have locked down my server really well using IP ranges - only incoming SMTP via spam server.

If I want to set up a forward on an email, do I need to set up a range to allow 127.0.0.1 to :
Allow SMTP
Allow deliveries from : Local to external e-mail addresses - with or without authentication

Or does hmail handle the forward regardless of the IP ranges ? ( it has after all already passed all the checks )

Any help very much appreciated

it will need IP ranges to send.There is a default button. Default is safe for most users.

I tried turning each port off individually in my internet IP range - and ended up stopping the in-flow of spam when I turned off IMAP. I suspect a clients account was hacked on cellphone/tablet.

Did you have any logging enabled?

If so, run your logs through Dooms Log analyser http://log.damnation.org.uk/
