Error while loading messages again about mail HOT 17 CLOSED

Got this too, happens when you receive an email with a hidden recipient list.
For me there is a Group "Verborgene_Empfaenger" on that mail.

The following fix works:

diff --git a/lib/Model/ConvertAddresses.php b/lib/Model/ConvertAddresses.php
index f723826c..78f5c554 100644
--- a/lib/Model/ConvertAddresses.php
+++ b/lib/Model/ConvertAddresses.php
@@ -71,7 +71,9 @@ trait ConvertAddresses {
        protected function convertAddressList($envelope) {
                $list = [];
                foreach ($envelope as $t) {
-                       $list[] = $this->hordeToAssoc($t);
+                       if ($t instanceof Horde_Mail_Rfc822_Address) {
+                               $list[] = $this->hordeToAssoc($t);
+                       }
                }
                return $list;
        }

That at least makes the list load again, not sure if the groups should be shown somehow or not.

So some update...

I just discovered that its some specific messages that cause the trouble. When the messages are not on the first page the folder loads fine. However as soon as I scroll down far enough the additional messages are not loaded. So I created a test folder with thunderbird and moved some messages to this folder. By doing so I found one malicious message that stops the folder from loading.

It's a mail with several umlauts and é and an attachment. Also it is forwarded and sent through a mailinglist... so all possible reasons to fail.

If I forward the mails to myself the problem is gone!
If I click 'edit as new' and send the mail to myself the problem persists!

What should I do next? I could send someone the problematic email but I don't want it posted here!

Any help is appreciated

Awesome. Yeah we'll need a solution like that because there is no common base class for group addresses and regular ones. We should show groups too somehow. Does that class provide anything printable?

from mail.

There is $t->groupname, $t->groupname_encoded and $t->label but all 3 are Verborgene_Empfaenger for me, so not really a nice printed version....

But I guess that is caused by the sender, so you can use either one of them.

I had the same problem, the fix from #53 (comment) works for me. Thanks @nickvergessen

So just to note you as I reported this issue: #53 is the "solution". So after applying this patch it works even with the hidden recipients mails. There is no marker, that there are additional recipients though!

Same issue on NextCloud 11 and PHP 7.0, fixed with @nickvergessen solution, thank you!

I hope this fix will be integrated soon.

I had the same issue with Nextcloud 11.0.2.7 and PHP 7. Would be great, if the fix will be officially integrated.

from mail.

With the fix in place, all my emails do show again.

Another duplicate, time to merge it @ChristophWurst ?

from mail.

Yeah time to open a PR @nickvergessen 😉

from mail.

Oh, I didn't do that? I thought this is where we discuss....

What? 😁

Same issue here on Nextcloud 12.0.0 and Mail App 0.6.4 on Apache2 / PHP7.

My nextcloud is called owncloud (for historical reasons)...

@dennisheitmann this will be fixed with Mail 0.7.0.
