    I get the following error when trying to send mail from Horde or other webmail programs:

    There was an error sending your message: Failed to set sender: email@email.com [SMTP: Failed to write to socket: not connected (code: -1, response: )]

    I have searched and found two suggestions - one is to enable SMTP_ALLOWLOCAL in CSF (which was already enabled with a "1"). The other suggestion was to ensure the Horde Identity had a valid email from address. I set the email address and this still has not resovled the problem.

    I tried completely disabling CSF to see if it was something caused by the firewall, but that hasn't helped.
    I have done a cPanel upgraded, checked SMTP settings in Tweak Settings and checked Security levels, but nothing has resolved this.

    Has anybody got an idea where I should look next?

    Was MySQL upgraded or downgraded recently on the machine? There are reports in our ticket system where a MySQL downgrade caused this to occur with Roundcube. I'm trying to determine if this might be the same cause.
