I'm using RC-0-1.1, PHP 5 and Mysql 5. The problem is that Roundcube refuse to send or foward a message with an attachment bigger than 1 MB, it shows an error:
PHP Fatal error: Allowed memory size of 16777216 bytes exhausted (tried to allocate 3300957 bytes) in /var/www/html/webmail/program
/lib/Net/SMTP.php on line 788
I'm wondering if someone has a solution to this problem.
