The date on the mayonnaise is likely not an expiration, but a "best by" date. The concern would not be food safety, but food quality - since the pH of commercially prepared mayo should not support the growth of pathogens, but the fats could be rancid. If the jar is still properly sealed and just a few days beyond the date, you could open it and give it a sniff test. How well it has kept depends upon several things, including storage conditions (heat, exposure to light, etc.)
Whether or not you use it is up to you. Mayo isn't all that expensive and you wouldn't want rancid mayo to ruin your recipe.

Is sweet relish still good if unopened and the expiration date has passed?
Depends on your definition of good. It isn't harmful but the taste deteriorates over time and the manufacturer has determined you get the best flavor if it's eaten before the expiration date. If it's only a month or two past the date I'd probably try it and see how it tastes. If it's two years past, I'd pitch it.
