Amavis – Clamd – Centos 7

I’ve ths error in /var/log/maillog:
(!)connect to /var/run/clamd.amavisd/clamd.sock failed

I solved in this way:

Edit /etc/clamd/clamd.conf

LocalSocket /var/run/clamd.amavisd/clamd.sock
User amavis

the User I defined (amavis), have to be the owner of the folder /var/run/clamd.amavisd
in the file /etc/amavisd/amavisd.conf you need the same file before : /var/run/clamd.amavisd/clamd.sock in this position
# ### http://www.clamav.net/
[‘ClamAV-clamd’,
\&ask_daemon, [“CONTSCAN {}\n”, “/var/run/clamd.amavisd/clamd.sock“],
qr/\bOK$/, qr/\bFOUND$/,
qr/^.*?: (?!Infected Archive)(.*) FOUND$/ ],

Configuration for helo hostname and accept mail without postgray check

1.
add the following to the /etc/postfix/main.cf configuration file

smtpd_delay_reject = yes
smtpd_helo_required = yes smtpd_helo_restrictions =
permit_mynetworks,
check_helo_access
hash:/etc/postfix/helo_access,
reject_non_fqdn_hostname,
reject_invalid_hostname,
permit

2.
create the file /etc/postfix/helo_access
and add your restriction like example:

myowndomain.com REJECT
pcname PERMIT

3.
create the database (you don’t need restart postfix)
postmap /etc/postfix/helo_access 

4.
postfix check
restart or reload postfix
/etc/init.d/postfix reload

or
/etc/init.d/postfix restart

print out configuration
postconf -n

mailq to see the mail in queue

To remove all mail from the queue, enter:
postsuper -d ALL

Accept mail without any postgray check:

vim  /etc/postfix/rbl_override

gmail.com OK

gmail.it OK

yahoo.com OK

hotmail.com OK

outlook.com OK

startcomca.com OK

libero.it OK

and my main.cf

smtpd_recipient_restrictions =
reject_unauth_pipelining,
check_helo_access hash:/etc/postfix/helo_access,
check_client_access hash:/etc/postfix/rbl_override,
reject_non_fqdn_recipient,
reject_unknown_recipient_domain,
permit_mynetworks,

#reject_rbl_client bl.blocklist.de,
#reject_rbl_client babl.rbl.webiron.net,
