[pfx] OT: VPS w/FDE suggestions?

2024-02-20 Thread MRob via Postfix-users
Hello- Im looking for <= $6/mo VPS suggestions for general mail/web 
hosting server. Some super-cheap hosts pre-install O/S and give root but 
I want to install O/S myself so can put in FDE. Hard to see which hosts 
can do this.


I tried Linode before and yes, could get FDE
($5 1GB, 1CPU, 25GB, 1TB)

Is IONOS any good? Can I get FDE there??
($2 1GB, 1CPU, 10GB, ?TB)
($3 2GB, 2CPU, 80GB, ?TB)
($6 4GB, 2CPU, 160GB, ?TB)

Others caught my eye:

hudsonvalleyhost
($3.95 1GB, 1CPU, 25GB, 20TB)
($6.95 2GB, 2CPU, 50GB, 20TB)

liquidweb
($5 1GB, 1CPU, 30GB, 1TB)

digitalocean
($6 1GB, 1CPU, 25GB, 20TB)

ovhcloud
($4.20 2GB, 1CPU, 20GB, 100Mbps unmetered)
($5.50 2GB, 2CPU, 40GB, 500Mbps unmetered)

brownrice
($5.95 3GB, 1CPU, 10GB, unlimited)

[pfx] dnsbl lookup binding address?

2025-01-23 Thread MRob via Postfix-users

Hellos!
I have see spamhaus response sometimes 127.255.255.254 that mean 
"generic" DNS lookup source.


I have three IPs on a virt server, one has PTR mail.exmple.com, other 
two are generic for hosting company


I guess spamhaus doesnt like when lookup comes from those 2 addrs 
instead of the main IP with custom PTR


Is that correct? If yes, can we make Postscreen dnsbl_sites lookup bind 
IP for lookups?


I already have inet_interfaces and smtp_bind_address set so I guess 
that's not used for dnsbl lookups?


Thanks for response!

This setting belongs to your system resolver.


Thank very much Bill Cole and Tomasz Pala reminding my mistake! Great 
appreciate.

I'm using zen.spamhaus.org for blocking and list.dnswl.org (with

for allowlisting.

zen.spamhaus.org*2 list.dnswl.org=127.0.[0..255].[1..3]*-2




Question occur to me, is there way to cease dnsrbl lookups once 
threshold is met? I think answer is "no" because Postscreen canot guess 
if there will be whitelist next.


Could be nice if there's trick to do:
* keep whitelist/blacklist lookup separate
* choose maximum needed threshold for each
* combine final points

I wonder coould it be possible so avoid too many dns lookup or reduce 
load upon public RBLs?
