    Good Day,
    Running ISPConfig 3.0.5.4p9 on Centos 6.8 and can't send emails through SendGrid.

    I've done this setup before, never had an issue (I believe I didn't have an issue?).
    Server Config / Mail / Relayhost (host, user, passwd)

    Does this mean this is a Sendgrid issue (certificate) or I'm missing some SASL packages?

    yum install cyrus-sasl
    Package cyrus-sasl-2.1.23-15.el6_6.2.x86_64 already installed and latest version
    Nothing to do

    yum install cyrus-imapd (installed this in case?)

    /var/log/maillog:

    Thank you in advance.

    As far as I can see, the issue is that your server does not trust the sendgrid ssl cert. Did you send the log snippet to their support?
