    1. You can definitely set the Return-Path header as a sender. But yes, some receivers might rewrite it (But not always ), or depending on who you're sending through, it might be re-written by them. For instance when using MailGun to send bulk email you have to do things just right in order to set a Return-Path that will be preserved. I know this contradicts the RFC you cite, but it's in practice true.
    2. Return-Path header is written by the receiving server, not by the sending server. And as per the RFC 5321, it is the same as the address supplied in MAIL FROM command.

    1. eMail hat tatsächlich nicht mehr den Stellenwert wie früher - als es wirklich noch wie schnellerer Briefverkehr genutzt wurde und deutlich förmlicher und verbindlicher war. Heute sehe ich das auch die Kundschaft eMail schon auf SMS-Niveau benutzt, was mir in der Seele wehtut, weil das eine völlig unwürdige Form der Kommunikation ist.

    1. Snail mail can be too slow, and email isn't secure. So that leaves us with the decades-old, but still reliable, fax.

      email is secure enough. Why do people keep perpetuating this myth?

    1. Hence an email address/mailbox/addr-spec is "local-part@domain"; "local-part" is composed of one or more of 'word' and periods; "word" can be an "atom" which can include anything except "specials", control characters or blank/space; and specials (the *only* printable ASCII characters [other than space, if you call space "printable"] *excluded* from being a valid "local-part") are: ()<>@,;:\".[] Therefore by the official standard for email on the internet, the plus sign is as much a legal character in the local-part of an email address as "a" or "_" or "-" or most any other symbol you see on the main part of a standard keyboard.
    2. There's a common design flaw on many many websites that require an email address to register; most recently I came across this bug on CNet's download.com site: for some reason they don't accept me when I try to register an email address containing a "+", and they then send me back saying my address is invalid. It isn't!
    3. "+" is a completely valid character in an email address; as defined by the internet messaging standard published in 1982(!) RFC 822 (page 8 & 9)... Any website claiming anything else is wrong by definition, plus they are prohibiting me and many fellow anti-spam activists from tracking where inbound spam comes from:

    1. URI::MailTo::EMAIL_REGEXP

      First time I've seen someone create a validator by simply matching against URI::MailTo::EMAIL_REGEXP from std lib. More often you see people copying and pasting some really long regex that they don't understand and is probably not loose enough. It's much better, though, to simply reuse a standard one from a library — by reference, rather than copying and pasting!!

    1. Carson Farmer noted that GMAIL is fundamentally a better user experience because individuals didn’t need to run their own protocols or set up their own servers.

      If so, why then not use ProtonMail that does not serve ads, abuse your data, and gives you the option for built-in e-mail encryption?
