You can try the following steps. First, in root SSH, run these commands:<\/p>\n

Code:
\ntouch \/etc\/blockeddomains
\necho \"domain.com\" >> \/etc\/blockeddomains<\/code><\/p>\n

Please replace domain.com with the domain name. Do not replace the “” part as that’s required, only the domain.com part with the right domain name.<\/p>\n

In WHM > Exim Configuration Editor > Advanced Editor, put the following in the topmost box:<\/p>\n

Code:
\ndomainlist blocked_domains = lsearch;\/etc\/blockeddomains<\/code>
\nLocate the “ROUTERS CONFIGURATION” section, and right below these lines:<\/p>\n

democheck:
\ndriver = redirect
\nrequire_files = \"+\/etc\/demouids\"
\ncondition = \"${if eq {${lookup {$originator_uid} lsearch {\/etc\/demouids} {$value}}}{}{false}{true}}\"
\nallow_fail
\ndata = :fail: demo accounts are not permitted to relay email<\/code><\/p>\n

Put the following lines:<\/p>\n

Code:
\nreject_domains:<\/p>\n

driver = redirect
\n# RBL Blacklist incoming hosts
\ndomains = blocked_domains
\nallow_fail
\ndata = :fail: Connection rejected: SPAM source $domain is manually blacklisted.<\/code><\/p>\n

Then, when trying to delete all messages from the spammy user you’ll see :<\/p>\n

[root@host \/home\/spammyuser\/public_html]# exim -bp | grep 'spammyuser' | awk '{print $3}' | xargs exim -Mrm
