    My VPS crashed during the night.

    It's running :

    CENTOS 6.5 i686 virtuozzo – server
    WHM 11.44.1 (build 7)

    The host advised that this is due to the SMTP tweak causing a conflict, they have disabled it and restarted the server. Is that a known issue and if so is having the SMTP tweak disabled going to pose problems re spam relayers ?

    Hello,

    I've certainly never heard of a conflict with SMTP Tweak causing the server to crash. Please ask your host for proof of that as that really makes no sense.

    Hi @oldlock,

    As Peter said, SMTP tweak shouldn't make the server to crash. Are you referring "SMTP Restrictions" at WHM ? or the misconfiguration of the exim configuration ?

    It shouldn't cause a crash, however, a LOT of virtuozzo VPSes do not have the IPT_OWNER or IPT_STATE iptables modules needed for SMTP restrictions, and SMTP Tweak (or CSF's SMTP_BLOCK) will not work without those kernel modules.
