New Firefox Service Will Generate Unique Email Aliases To Enter In Online Forms (zdnet.com) 70

An anonymous reader writes: Browser maker Mozilla is working on a new service called Private Relay that generates unique aliases to hide a user's email address from advertisers and spam operators when filling in online forms. The service entered testing last month and is currently in a closed beta, with a public beta currently scheduled for later this year, ZDNet has learned. Private Relay will be available as a Firefox add-on that lets users generate a unique email address -- an email alias -- with one click. The user can then enter this email address in web forms to send contact requests, subscribe to newsletters, and register new accounts. "We will forward emails from the alias to your real inbox," Mozilla says on the Firefox Private Relay website. "If any alias starts to receive emails you don't want, you can disable it or delete it completely," the browser maker said.

      Would be nice if there was an open source implementation that you could run on your own domain. That would be far less likely to get banned.

      • I agree, I feel like something like this wouldn't be hard to do at all. I mean if you own your own SMTP server, you could literally just create an account for a purpose, use it until your done with it and get rid of it. I can't imagine it would be too hard to automate it with a simple UI either.

          Many email servers support plus addressing. Mine does, as you can see above. If an address gets spam you know who is responsible. That saves a lot of trouble. Obviously that scheme can reasonably easily be ruined by smart spammers.

            Yea but many websites don't support it. I've tried it in the past and about 50% of the time the form validation flags it as invalid (even though it obviously is valid).

              It depends on the character used to separate the base and added parts of the email address.
              I found that many sites (improperly) reject the '+' character that Google uses, so I configured Postfix for my own domain to use the underscore.

            Maybe the scheme could still work no matter how smart the spammers are with some revisions.... if you use a suffix for ALL contacts, and if no suffix is given: Have that go to an auto-reply bot instead of a mailbox... a bot that only responds to messages that come from a sender passing DMARC alignment with SPF or DKIM.

          You can just set to a domain that redirects all mail to your real account and block individual addresses as they get spammed, but it's a bit of work and when someone does a dictionary attack against it you are in trouble.

          Something like this that makes it as easy as a few clicks would be great.

        • I think it would be easy, to write a browser add-in that automatically creates a new adress on the fly at some provider, by filling in the mail account creation forms with random data and such, do the entire verification process, and merely ask you to enter a CAPTCHA or the like that can't be automated.

      • I've been doing this for a decade. The back-end of my mail server is SQL-based, and it has a table that maps aliases to actual accounts (even those not on my server).

        Postfix looks up any inbound address against that table to decide whether to accept it, then hands it of to the LMTP server, which delivers it to the real address.

        I've only occasionally thought of implementing a web page to allow remotely setting them up.

      Nice, let's hope services don't ban the aliased emails though. I noticed this happen with the apple id email security.

      There's a simple solution for that -- if a merchant doesn't accept your aliased email address, don't do business with that merchant. You're the one with the money, if they don't want to accept your money on your terms, don't give it to them.

      It's like if a brick and mortar merchant refused to do business with you if you don't provide your phone number (I'm looking at you, Radio Shack), if they won't accept your obviously fake number (I used 415-555-5555), then buy your batteries somewhere else.

        Just to give an opposite perspective: as a merchant who has persistent problems with a small number of customers whose email addresses don't work, sometimes because their ISPs insist on non-standard behaviours and treat anyone who doesn't comply with their pet wish list as junk or even drop the mail silently, please go ahead. I would be delighted if the tiny fraction of our customers who have broken email just went away, because they cause considerable stress and wasted time, sometimes even generating more

    • by Kjella ( 173770 )

      Well I don't really see this as a service for throwaway mail, more like compartmentalized mail. Like you actually want to read them in a timely manner and without logging into dozens of different accounts, but without giving each and every one of them the chance to sell your email to spammers and compromise your true inbox. Throwaway emails are more those "fire-and-forget" emails I use when somebody requires email activation, where I rarely or never need to check that inbox again.

    • I don't want throwaway addresses, I want fixed ones I can turn on and off. Eg I have an account with Ebay, and Ebay spew spam constantly. But I need to have my email address (unique to them) turned on while I am selling something, though I turn it off in between times. If I "threw away" an Ebay address after every time I sold something it would be a flaff to keep creating a new one for them, even if they allowed that (IDK).

    Can do this. I've done it for a few years now. Any new account I setup gets a new alias on my server. If they get too spammy, I just remove the alias. It is way more work though than this firefox feature though.
    • Same. With my own domain name, each website I buy from/register with gets a unique email address.

      So far, I've caught a major railway, MLB organization and 2 large ecommerce sites giving those email address to 3rd party marketers. Plus, a few smaller online stores.

      Sadly - while each got reported to the federal govn't anti-spam organizations, nothing has been done.
    • Same here but instead of maintaining an list of aliases or having to go create one before I use it, I use the address extension character. Typically + I changed mine to a -

      so me-subj@mydomain gets to me@mydomain but keeps the -subj part.

      Should I get too much spam then I create an actual address/alias for it that ends up delivering it to /dev/null

    Been using that capability using a wildcard feature of PostFix for over 10 years. I can say it has been one of the best features of email I can imagine.

    To give an example, after there were fraudulent purchases on my credit card, I was able to identify the vendor that leaked it because the thief used an email address to sign up for a service with my credit card that I only gave to this vendor.

    I can also send specific email addresses to /dev/null that become spam targets without impacting incoming emails I care about.

    Very glad to see Firefox begin to open this type of capability to the public.

    • Same here, except about a decade and half ago I switched from sendmail+qmail to MSFT Exchange which also has had wildcards forever. After many years of using wildcard emails, I have a decent sized filter which silently discards a whole bunch of them. I also have some spam filters which filter based on both source and destination, for example any email which claims to be from amazon.com goes straight to Junk Mail unless it comes to the email which I only use with Amazon. Same for banks, etc.

    1) Mozilla has to have an SMTP relay server running and if many people start using this service it might mean a lot of expenses. Also some email providers may refuse to allow SMPT relay in principle.

      Also some email providers may refuse to allow SMPT relay in principle.

      That criticism isn't valid / does not make sense. Email providers by their very nature have to accept SMTP connections from other MTAs relaying traffic to the destination domain's MX servers; that's how e-mail routing on the internet works.

      If the account is really important, then you should probably be giving them your real e-mail address rather than one relying upon a 3rd party relay service to reach you.

    I've been arguing for years that we need new kind of service, along the lines of an identity provider. What I'm imagining is a single service that wraps together all of your account management in one service (SSO, email address management, account management), while not including in it any other service (e.g. storage, mailbox hosting). The main service that they would provide is to be a universal authenticator and account management system, so that I can p

      What do you mean "like Google"?

      These wildcard addresses have existed long before Google and are supported by many MTAs. You can also place dots anywhere in the local address (part before the @) since dots are ignored (i.e., hello@abc.com = h.e.l.l.o@abc.com = h....e....l...l...o@abc.com).

      In fact, the mail address standard allows (almost) any character in the local part of an address (see the address specification in RFC 5322 [ietf.org], which finally resolves to atext [ietf.org]).
