(Likewise "plus addressing" is not part of any standard and not guaranteed to work on all mail providers.)
Many websites have cottoned on to it will either disallow a + in the email address entered (which is naughty of them to do) or strip off the plus addressing (for known domains where it is handled, such as google) as it gives a higher chance of the email being read.
(I've run my own mailservers in the past so I get around things like this by using my own version of plus addressing. Since I control the config I could make it so I could use bob<anything>@example.com without needing to use the + symbol, so bobblah@ bobfoo@ bob@ bobwiggle@ would all go to the same address. But, I'm too old/tired/cynical to run my own mailservers any more and the big boys all have a deliverability cartel going so it's easier to just use one of theirs.)
