SMTP Error ($code): Message size exceeds server limit

[dkorzhevin]

Hello guys,

I can't do anything with this error:

"SMTP Error ($code): Message size exceeds server limit"

Exim message size server limit is 15Mb, all other limits seems to be ok.. Error is shown when i try to send message with attachment bigger than 11 Mb.

Maby problem somwhere in code here:

roundcube/program/lib/Net/SMTP.php ?

        /* RFC 1870, section 3, subsection 3 states "a value of zero indicates
         * that no fixed maximum message size is in force".  Furthermore, it
         * says that if "the parameter is omitted no information is conveyed
         * about the server's fixed maximum message size". */
        $limit = (isset($this->_esmtp['SIZE'])) ? $this->_esmtp['SIZE'] : 0;
        if ($limit > 0 && $size >= $limit) {
            $this->disconnect();
            return PEAR::raiseError('Message size exceeds server limit');
        }

Hi!

Maybe you take a look at your php.ini and .htaccess.


Have a nice day!

That's sounds about right... most likely it is a php configuration or a webserver configuration

Check your php.ini as mentioned in the previous post

Look and define the size desired:

upload_max_filesize = 10M
post_max_size = 10M

Attachments in mail message are encoded using base64, it means they are ca. 0.33% bigger. So, 11MB => 15 MB.

Hi!

You mean ~30%, right?

Have you i.e. test it with a "20M" config?

Thank you for answers,

i double checked my php.ini config and set:

Configuration File (php.ini) Path => /etc/php5/cli
Loaded Configuration File => /etc/php5/cli/php.ini

/etc/php5/cli/php.ini

upload_max_filesize = 30M
post_max_size = 30M

and .htaccess in roundcube folder:

php_value       upload_max_filesize     30M
php_value       post_max_size           30M

But this still not helps. I even increase exim4 letter size limit from 15M to 30M, without no result.

Any ideas?

Are you sure? Enable sql_debug in Roundcube and you'll see what size limit really is there. The error message is from SMTP communication.

smtp_debug of course not sql_debug.
