Applicable to:

  • Plesk 12.5 for Linux

Symptoms

  1. Unable to make SSL connection to mail sever using 3rd-party mail clients.

    Windows Security update KB3061518 is installed on client side.

Resolution

As workaround, perform these steps:

  1. Edit /usr/share/mkdhparams file changing marked strings:

      cp /dev/null /usr/share/dhparams.pem.tmp
    chmod 600 /usr/share/dhparams.pem.tmp
    --> chown root /usr/share/dhparams.pem.tmp

    BITS="$DH_BITS"
    if test "openssl" = "openssl"
    then
    if test "$BITS" = ""
    then
    --> BITS=1024
    fi
  2. Remove existing certificate:

    # rm -f /usr/share/dhparams.pem
  3. Generate new:

    # /usr/share/mkdhparams
  4. Restart courier services:

    # service courier-imapd restart
    # service courier-imaps restart
