Closing. There's been substantial work done in Horde_Mail the last 10 days so this should be fixed (at least in Horde 5/IMP 6/Horde_Mail 2).

Turns out that even with new IMP code, there were some bugs in IDN parsing with the new code. (For the record... it is really difficult to write a parser that strictly conforms to the RFC AND allows loose-parsing for more natural-language type input.) I'll leave open to verify that Horde_Mail 1.2.0 and IMP 5.0.19 fix.

HORDE: [imp] Validation failed for: test@überfall.de [pid 16934 on line 972 of "/var/www/webmail/imp/lib/Compose.php"] Are you using the latest IMP from git master? There is no validation near that line. E-mail validation has been completely rewritten lately - since 5.0.18 was released. No sorry. I should have logged the issue against IMP or mention in the report which packages versions I use as this queue doesn't support any reasonable values for the framework packages. imp-5.0.18 Horde_Mail 1.0.3 Horde_Mime 1.4.1 And it looks as though Horde_Mime::encodeAddress('Räuber <raeuber@überfall.de>', 'UTF-8') Yes - encodeAddress() does not support IDN. That's why it is deprecated and why future manipulation of e-mail addresses is going to be done solely through Horde_Mail_Rfc822 methods/objects.

I ensured that the PECL IDN package is available. This won't work - we don't support the PECL IDN package. You need the intl extension. See horde/docs/INSTALL.

A customer reported issues with sending mails to IDN domains ("Validation fails"). I tried to test this and to me it looks as if this is currently not possible. The ~~bug #5180~~ is closed though so I might just have overlooked something. I ensured that the PECL IDN package is available. The error I get is HORDE: [imp] Validation failed for: test@überfall.de [pid 16934 on line 972 of "/var/www/webmail/imp/lib/Compose.php"] And it looks as though Horde_Mime::encodeAddress('Räuber <raeuber@überfall.de>', 'UTF-8') yields an invalid result ('"\274berfall.de>"@') There are some idn setting available in Horde_Mime_Address but I don't see how this IDN parsing could be used when encoding the address.
