Colon symbol in address name

[aliismayilov]

let!(:mail) { IssueNotifierMailer.digest }

it { expect(mail).to deliver_from("HE:tech <tech@example.com>") }

Our company has a colon in its name. Sending from HE:tech <tech@example.com> does not create any problems. But when I try to test it with expect(mail).to deliver_from("HE:tech <tech@example.com>") I receive following error:

Failure/Error: it { expect(mail).to deliver_from("HE:tech <tech@example.com>") }
Mail::Field::ParseError:
  Mail::AddressListsParser can not parse |HE:tech <tech@example.com>|
  Reason was: Expected one of
  , (, ,, ; at line 1, column 29 (byte 29) after :tech <tech@example.com>

@aliismayilov It isn't an issue. I took a look and it's raised by mail gem. Mail gem implementation follows a RFC. So, I put below the reason of not accept colon on any email header body.

2.2. Header Fields

   Header fields are lines composed of a field name, followed by a colon
   (":"), followed by a field body, and terminated by CRLF.  A field
   name MUST be composed of printable US-ASCII characters (i.e.,
   characters that have values between 33 and 126, inclusive), except
   colon.  A field body may be composed of any US-ASCII characters,
   except for CR and LF.  However, a field body may contain CRLF when
   used in header "folding" and  "unfolding" as described in section
   2.2.3.  All field bodies MUST conform to the syntax described in
   sections 3 and 4 of this standard.

[sirkosi]

All non-standard characters need to be in quotes according to RFC822.
The email mentioned should be something like "HE:tech" <tech@example.com>

I'm closing this issue, thanks.
