Place the cucumbers, cabbage, onion, and red bell pepper in a medium-sized nonreactive mixing bowl and sprinkle with salt, stir well. Let stand for 1 hour.
Drain the mixture in a colander, rinse under cold water, and drain again, pressing out any excess moisture.
In a medium-sized nonreactive saucepan, combine the vinegar, sugar, prepared mustard, dry mustard, mustard seed, celery seed, paprika, turmeric, and cornstarch. Whisk until fully blended. Bring to a boil. Reduce the heat and simmer until the sugar has dissolved and the mixture has thickened slightly.
Add the cucumber mixture, and return the mixture to a boil. Reduce heat and simmer for 10 minutes, stirring occasionally.
When the relish has finished cooking, transfer it into a sterilized pint jar and refrigerate until cool, then cover. Store in the refrigerator for up to 2 months.
