Topic: Block Email from Domain

[Bud]

guys please help

i need to block email received from a certain domain being sent to users on my sme 9.1 server

eg: Somebody from Domain x somebody@domainx.com is sending mail to my user(s) on my sme 9.1 server user1@mysmeserver.com

i need to blacklist the domainx.com so that NO email will be delivered to my sme 9.1 server

Logfiles? e.g. qsmtpd logs?

something like

Code: [Select]

grep logterse /var/log/qpsmtpd/current | grep  'domainx.com' | tai64nlocal

should do the trick

RequestedDeletion and stefano thank you for your input much appreciated

i have installed the https://wiki.contribs.org/Email_Whitelist-Blacklist_Control contrib and have done the following as a test on my sme 9.1 server

server-manager > E-mail WBL > Black List

i placed an entry in qpsmtpd badhelo " somebody@domainx.com " ( without the inverted commas )
i placed an entry in  qmail badmailfrom " somebody@domainx.com " ( without the inverted commas )
i have placed an entry in spamassassin blacklist_from " somebody@domainx.com " ( without the inverted commas )

i then did a test using

the email is NOT blacklisted and still goes to the users mailbox ie the email is NOT being rejected.

i require the email from somebody@domainx.com to NOT be delivered to any user on the sme 9.1 server

any ideas what i am doing wrong

Did you do a signal-event post-upgrade; signal-event reboot after installing the contrib? And is your server fully updated?

How did you do the testing ?

Is the email address you want to block in the list when you do :

Code: [Select]

cat /var/qmail/control/badmailfrom
what does this show :

Code: [Select]

grep logterse /var/log/qpsmtpd/current | grep  'check_badmailfrom' | tai64nlocal
On several servers i manage i see this when blocking a sender :

Code: [Select]
