One of my favorite GMail features is plus addressing [?]. I already, with my domain, hand out tons of aliases when signing up for things, and so being able to continue that method of tracking where an email address was harvested from is very useful.

Today I received five pieces of spam, all of them were sent to my gmail address without the trailing + part. Meaning, I believe, that spam harvesting spiders are smart enough to clip that little tag off before committing the address to their database. I don't believe I have ever placed my address on a spiderable page without some sort of + addressing tag.

Also, two web forms I have filled out in the past week have filtered the + in my gmail address as a space (which is understandable, it's a method of urlencoding spaces), rendering the account I was creating unusable.

I like the idea of plus addressing, but I am afraid it's not going to be as useful as I had hoped if spam harvesters are clever enough to know when they're being tricked, and web developers are filtering out the plus character in registration pages.



spiders can indeed cut off + addresses. However, I use a unique name, e.g., or So far, these seem to foil them. Well - not foil them really, but I can just filter out the address once it becomes spam infected - and I know where it was harvested from.


I think that's what torrez was talking about in his first paragraph.


I've already gotten some + addressed spam, after just using it a handful of times. (I haven't gotten any where the address has been truncated, though). This was harvested from my own site, fittingly. Oh well... at least the filter caught it.


The harvesters may not actually be smart. Progranners who haven't read the RFC often think that + is not a legal character in email addresses and code under that assumption. Depending on how it is written, a parser could easily mistake the + for then end of your address rather than part of it.
