寻找包含一组单词的正则表达式
Looking for a regular expression which does contain a set of words
我正在尝试为我的 Postfix header_checks 文件创建一个正则表达式,以便它匹配 不 包含 .com、.net 或 .org 的字符串域扩展。
以下正则表达式似乎在 regex101 中有效,但在 Postfix 中失败。
/^From: .*\.(?!(com|net|org)>)/ HOLD
所有邮件(包括 .com、.net 等)都排在队列中,这显然不是我想要的。
我希望正则表达式匹配如下字符串:
From: Example Mail <example@domain.bid>
From: Example Mail <example@domain.bid.co>
知道我的正则表达式哪里出了问题吗?
根据regexp_table正则表达式匹配多行
模式关闭,这意味着 ^
只匹配字符串的开头而不是
行首。
By default, matching is case-insensitive, and newlines are not treated
as special characters. The behavior is controlled by flags, which are
toggled by appending one or more of the following characters after the
pattern:
i (default: on)
Toggles the case sensitivity flag. By default, matching is case
insensitive.
m (default: off)
Toggle the multi-line mode flag. When this flag is on, the ^ and
$ metacharacters match immediately after and immediately before
a newline character, respectively, in addition to matching at
the start and end of the input string.
(顺便说一句,我更喜欢 "[.]"
而不是 "\."
并且会使用非捕获组来替代:"(?:com|net|org)"
)。
