Can't display some messages

[yasuhirokimura]

Recently I've been facing the issue that SnappyMail can't display some messages. Following is an example of such ones.

https://lists.freebsd.org/archives/dev-commits-ports-all/2023-July/072697.txt

If I crick such message, then it is displayed in message area in a instant but "Unknown error" is displayed as following.

I have following two instances of SnappyMail.

1. FreeBSD 13.2-RELEASE amd64, PHP 8.2.8, Apache 2.4.57, SnappyMail 2.28.4
2. Debian 11.7 amd64, PHP 7.4.33, Apache 2.4.56, SnappyMail 2.28.4

And if I try to dispaly the message in question on the same IMAP server. The issue happens with instance 1 but not with instance 2. So it may be related to PHP version.

I use Avatars plugin and the issue disappears if I disable it. As I wrote above I have instance with PHP 7.4. And the issued doesn't happen even if I enable Avatars plugin on it. So the source may be combination of PHP 8.2 and Avatars plugin.

I made another instance of SnappyMail with following conditions.

• Debian 12.1 amd64
• PHP 8.2.7
• SnappyMail 2.28.4

And the issue doesn't happen even if I enabled Avaters plugin. So there may be no relation between the issue and PHP version.

I'm having the same issue after updating my server to Ubuntu 22.04.3 LTS - which updated PHP from 7.x to 8.1.2. (All SnappyMail extensions are disabled.)

After enabling logging, I found the culprit:

Error: Class "DOMDocument" not found in .../snappymail/v/2.11.0/app/libraries/MailSo/Base/HtmlUtils.php:97

Turns out, the system update ate the xml-dom package. I was able to resolve the issue by (re?)installing that:

apt-get install php-dom

And on Centos / Fedora / Red Hat:

yum install php-xml

[yasuhirokimura]

1. The system in question is FreeBSD.
2. Both php82-dom and php82-xml are installed in it.
3. As I previsouly wrote, the issue happens only if Avatars plugin is installed and enabled.
4. I enabled logging but no error message is written when the problem happens.

So I think my case is different from yours.

With PHP 8.2.1 i have no issues. Could it be related to enabled BIMI or Gravatar setting?

[yasuhirokimura]

Before facing the issue I used Avaters plugin with following setttings.

1. Identicon: Name characters else silhouette
2. Enable "Preload valid domain icons"
3. Enable "Delay lookup"
4. Enable "BIMI"
5. Enable "Gravatar"

So I disabled 4 and 5. Then the problem disappears.

Though I'm not sure if it is releated, I found odd behavior of Avaters plugin while investigating the issue.

As I wrote above, currently I use Avaters plugin with following setttings.

1. Identicon: Name characters else silhouette
2. Enable "Preload valid domain icons"
3. Enable "Delay lookup"
4. Disable "BIMI"
5. Disable "Gravatar"

And with this settings avater is displayed if I open messages that come from amazon.com, github.com, google.com, etc.

It doesn't happen if I disable "Delay lookup".

Is it expected behavior?

So the source may be combination of PHP 8.2 and Avatars plugin.

I think i fixed it for next release. There was a problem with the json.after-* hooks. The $aResponse array wasn't recursive as the result wasn't converted to json yet.

Any luck with v2.31.0?
