Sending hostname being incorrectly added to email address on send

[abeverley]

I am not sure whether this problem is within Mail::Message itself or the MTA (Postfix).

Under certain circumstances (a long phrase including a semicolon) the hostname gets appended to part of the phrase. The following example demonstrates it:

my $e = '"John Smith ;Connor - this is some additional text to make long phrase" <andyjohns@example.com>';

my $msg = Mail::Message->build(
    To      => 'something@example.com',
    From    => $e,
    Subject => "My subject line",
    data    => "Some body text",
);

my ($from_orig) = $msg->from;
my $from = Mail::Message::Field::Address->parse($from_orig);

my $f = Mail::Message::Field::Address->new(
    address => $from->address,
    phrase  => $from->phrase,
);
$msg->head->set(From => $f);

$msg->send(via => 'postfix');

When this arrives at the recipient, the from email address has changed to:

"John Smith @www.example.com;Connor - this is some additional text to make long phrase" <andyjohns@example.com>

It seems that something is considering the semicolon an address separator and is then appending the local hostname to the phrase before it.

The current implementation used the RFC2045 rules for Quoted-Printable Transfer Encoding. This was a mistake: it should have been the RFC2047 section 4.2 & 5 definition, which has a smaller set of acceptable characters. So: the ';' was not allowed here.

Issue #2 was slightly different: that one was about the need for being more flexible in receiving encodings.
