Could you please clarify what your question is?

 

[oim37]

I get a lot of spam to root@domain1.tld, root@domain2.tld addresses, for all domains, how to disable it. Didn't notice this before, i find this https://support.plesk.com/hc/en-us/...s-in-var-spool-postfix-plesk-virtual-database and think that localhost.localdomain is reason of this.

It is not advised to remove the root mailbox, because this is needed for all important server notifications. If spam is sent to "root" in virtual domains, it is automatically delivered to your root mailbox.

Are your using DNS blackhole lists in your Tools & Settings > Mail Server Settings? These can decrease incoming spam. DKIM and SPF with strict rejection can also help.

Yes i have this settings, it marked as spam and going spam folder. I don't like that it comes from all domains on root@, increases the number of letters at times, can't i do something to allow for only one main domain?

Just for history: It is possible to customize a set of system aliases starting with Plesk Obsidian 18.0.66.

- (Plesk for Linux) Added the ability to stop accepting mail sent to preconfigured aliases such as root, postmaster, or anonymous on Plesk servers using Postfix or qmail as the mail server. By default, such emails are delivered to the Plesk administrator’s mailbox.

I really appreciate it.

 

[oim37]

I update plesk to latest (18.0.66)

Some time ago see that i receive email send to root@clientdomain123.tld, i go see manual in changelog and think that need run plesk repair mail -y but after complete i receive new email to root@anotherclientdomain456.tld

In panel.ini i not have config with strings: [mail] and adminAliases

or i need to make this

[mail]
adminAliases =

with empty string after =?
P.S. Provided that I do not want to receive emails from third-party domains for all aliases.

 

[AYamshanov]

Yes, you need to add a new section (if it is not existing) with a new option and leave the value empty,
As an example, I made changes with the Panel.ini extension,



Here are numbers before and after the plesk repair mail -y command (was 8 "postmaster" aliases, then 0)

# /usr/sbin/postmap -s /var/spool/postfix/plesk/virtual | grep postmaster | wc -l
8

# plesk repair mail -y
