[pfx] Question about postscreen

2023-11-02 Thread Ivan Ionut via Postfix-users



Hi, it's possible that  postscreen does not block the email when 
postscreen_dnsbl_threshold is reached but to pass that email to 
spamassassin(with a score and a tag).

[pfx] Allowing receiving mail but I prevent sasl authentication

2023-10-19 Thread Ivan Ionut via Postfix-users



Hi, is there a way to block an ip(or ip cidr) to do sasl authentication 
but allowing to receive mail from it.


I'm asking because some times I may completely block the god guys from 
my firewall.


p.s. sorry for my english

[pfx] Postscreen dnsbl logs

2023-10-16 Thread Ivan Ionut via Postfix-users



Hi, I'm using postscreen dnsbl configuration to block some spam:

postscreen_blacklist_action = drop
postscreen_dnsbl_threshold = 4
postscreen_dnsbl_action = enforce
postscreen_dnsbl_sites =
zen.spamhaus.org
b.barracudacentral.org
bl.spameatingmonkey.net
bl.spamcop.net
dnsbl.sorbs.net
dnsbl-1.uceprotect.net
dnsbl-2.uceprotect.net
dnsbl-3.uceprotect.net
spamsources.fabel.dk
rbl.abuse.ro
bl.blocklist.de
bl.0spam.org
truncate.gbudb.net
spam.dnsbl.anonmails.de
cbl.abuseat.org
hostkarma.junkemailfiltebeltimeblacklist.com=127.0.0.2
rbl.dns-servicios.com
rbl.interserver.net
spam.spamrats.com
ubl.unsubscore.com
dnsbl.dronebl.org
z.mailspike.net
bl.mailspike.net
dnsbl.zapbl.net
dnsbl.cobion.com
db.wpbl.info

 And in my logs I have this example of blocked email(a non-spam one):

blocked using dnsbl-2.uceprotect.net
blocked using spam.dnsbl.anonmails.de

So only two of them, not four. And I want to know if there is a way to 
log more information about the threshold for each rejected email(maybe 
for each dnsbl_site).


My postfix version: 3.6.4;

[pfx] Question about postscreen_dnsbl_sites

2023-10-11 Thread Ivan Ionut via Postfix-users



Hi, I'm using postscreen_dnsbl_sites to block some spam and I want some 
domain/hosts/ip to bypass this option, like an whitelist.


Does postscreen/postfix has this option?

p.s. my postfix version: 3.6.4
