Sometimes attachments are lost from emails.

[Kentaro]

Hi,forum.

I'm runnning an email system using roundcube on RHEL 8.4.
(Roundcube:1.4.11-2,dovecot:2.3.8-9,Postfix:3.5.8-1)

When sending e-mail with attachment(file), sometimes file are not attached.
While writing e-mail,we cheked these files are attached.

The following sentences is the result of our investigation.

The log output looked as if the mail was sent with no files attached.
As a point of investigation, we checked if the mail size in /var/log/maillog included the size of attachments.

In addition, /var/log/httpd/access_log does not output any logs that indicate that attachments were deleted on the roundcube side.

From the above,We assume that the attached files are not being attached on the roundcube side due to some kind of bug.

Sounds similar to #8415. Do you use the database_attachments plugin?

The 1.4.x version of Roundcube reached EOL in October 2023 please consider updating.

Certainly events similar to those in this thread are occurring.

We use the database_attachments plugin.
Is this plugin related with this problem?

The 1.4.x version of Roundcube reached EOL in October 2023 please consider updating.

We'll consider it.
Thanks.

I will update roundcube, but users are wondering if this is the solution.
Do you think an update will resolve this issue?
