    Hi,

    I am still having little bit confusion for choosing "nobody", (Which setting will prevent nobody from sending email on/off ?) What should I choose, Off or ON ?

    Prevent “nobody” from sending mail [?]
    Prevent the user “nobody” from sending out mail to remote addresses
    (PHP and CGI scripts generally run as “nobody” if you are using mod_php or have Suexec disabled.)

    I have checked "Configure PHP and suEXEC"

    PHP 5 Handler configured value is suphp
    Apache suEXEC configured value is on





    And
    Enable WHM's SMTP Restrictions
    Spammers commonly attempt to work around mail security settings by interacting directly with remote mail servers. WHM's SMTP Restrictions can prevent users from doing so.

    In CSF configuration there is a same option of "SMTP_BLOCK"
    This option in WHM will not function when running csf. You should disable WHM > Security Center > SMTP Tweak and use the csf configuration option SMTP_BLOCK instead


    Which one is recommended cPanel's "SMTP Restrictions" OR CSF's "SMTP_BLOCK"

    Please advise ?

    Hi Infopro,

    Thanks for quick reply as usual,

    If I make it ON will our client get inquiry form mails on their website's inquiry page ?

    My Apologies for poor English

    regards,

    Testing it for yourself might be best. No way of knowing what sort of form is being used, or if its setup to use SMTP or not. (preferred)

    So if form is not using SMTP authentication, isn't it more likely to be a spammer script?

    Yes, and if you're on a self managed VPS the email then comes from your cpanel username and the hostname, like cdebo@ab.cdef.com which has no spf, dmarc, fails sender verify, etc and can get you blacklisted very quickly.
