| 名字 | 默认 | 可修改范围 | 更新日志 |

imap.enable_insecure_rsh
boolean
Establishing a connection to a server may invoke rsh or ssh commands, unless this php.ini option is disabled.
Neither PHP nor the IMAP library filter mailbox names before passing them to rsh or ssh commands, thus passing untrusted data to this function without disabling this php.ini option is insecure.
