The convention has existed almost as long as there's been sendmail, and is available in postfix too. This is handy to direct incoming email into different boxes, and makes it possible to narrow down who leaked your email address. Indeed: I use it for my subscription to mailop as you can see. UNFORTUNATELY, many web sites outright refuse to accept "+" as a valid character in an email LHS, despite the fact that the RFC's permit it. In fact, I've run into occasions where the "new user" function permits it, but logging in and/or password change *don't*. Worse was one that entirely disabled it long after I've been using it successfully, routinely. Sometimes significant ones with paid subscriptions/services. Pain in the ass they are. It's useful, but be aware that some sites screw it up. Some relatively major ones. _______________________________________________ mailop mailing list mailop@mailop.org<mailto:mailop@mailop.org> https://nam06.safelinks.protection.outlook.com/?url=https%3A%2F%2Flist.mailop.org%2Flistinfo%2Fmailop&data=04%7C01%7Cmichael.wise%40microsoft.com%7C5f74fabf414d4239fdfd08d8cd44c948%7C72f988bf86f141af91ab2d7cd011db47%7C0%7C0%7C637485042623041470%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C1000&sdata=zAseu%2F%2BY2FAyY4TyB2ZH5cHQW%2FxzyJqUbrFPG0GJ6kU%3D&reserved=0
