    When I try to send an email through webmail to another local user, I receive the SMTP (-1) error.

    This happens even using the mail's server to send emails.

    I keep finding solutions that mentions CSF or other firewall, local setting, regarding SMTP_Block or SMTP_ALLOW, but all options in cpanel or firewall that could use this are disabled.

    Any ideas?


    Thanks

    If you have CSF installed, try disabling it temporarily.

    WHM >> Plugins >> CSF Security & Firewall >> Firewall Disable

    I don't have CSF installed, all the solutions I find are around it...

    But thanks.

    Any other idea?

    Hi @Jose_Marques

    Can you please show me the error as it appears in /var/log/exim_mainlog?

    Thanks!

    I issued a ticket on CPanel, I'm being helped by customer support.

    If a solution is found I'll post.

    Thanks!

    It appears that ASSP ( third party software ) was messing this up.

    Stopped assp, ran reset of Exim configurations and looks to be working fine.


    Next stop, making sure that ASSP is not badly needed, if so, working that out.

    Hi @Jose_Marques


    Thank you for the update, the 3rd part software ASSP is known to cause some issue with the functionality of cPanel's implementation of exim. I'm glad you got the issue sorted out and thanks for letting us know the cause of it!
