部署了iredmail系统后，经常会在postmaster账户下收到系统的报错邮件，邮件内容如下：
PHP Fatal error: Allowed memory size of 2097152 bytes exhausted (tried to allocate 163840 bytes) in /opt/www/roundcubemail-1.5.3/program/lib/Roundcube/rcube_charset.php on line 365
我已经在/etc/php/7.4/fpm和/etc/php/7.4/cli目录下都修改了php.ini文件，将memory_limit修改为1024M，但还是会经常收到这个报错邮件。
