Postfix + LDAP + 收件人分隔符

tag-icon • tag-icon postfix ldap
Postfix + LDAP + 收件人分隔符

我正在尝试让我的 Postfix 和 LDAP 后端接受收件人分隔符（又名地址扩展）。

邮件系统的其余部分工作正常，但当收到带有扩展名的电子邮件时（例如[电子邮件保护])，它尝试在 LDAP 服务中查找“coops+test”，但失败了。显然这是错误的，它应该删除“+test”部分。

在我的 postfix 配置中，传递给 LDAP 服务的字符串是“％s”，如下面的示例行所示：

accounts_query_filter = (&(objectClass=MailAccount)(mail=%s)(accountActive=TRUE)(delete=FALSE))

是否有一个后缀变量代表电子邮件帐户减去扩展名？我找到了一个类似的帖子这里，但没有实际的解决方案。

根据手册页 ldap_table(5)，可能性有：

%%     This is replaced by a literal ’%’ character. (Postfix 2.2 and later).

%s     This is replaced by the input key.  RFC 2254 quoting is used to make sure  that  the  input  key
       does not add unexpected metacharacters.

%u     When  the  input  key  is  an  address of the form user@domain, %u is replaced by the (RFC 2254)
       quoted local part of the address.  Otherwise, %u is replaced by the entire  search  string.   If
       the localpart is empty, the search is suppressed and returns no results.

%d     When  the  input  key  is  an  address of the form user@domain, %d is replaced by the (RFC 2254)
       quoted domain part of the address.  Otherwise, the search is suppressed and returns no  results.

%[SUD] The  upper-case equivalents of the above expansions behave in the query_filter parameter identi‐
       cally to their lower-case counter-parts. With the  result_format  parameter  (previously  called
       result_filter  see the COMPATIBILITY section and below), they expand to the corresponding compo‐
       nents of input key rather than the result value.

       The above %S, %U and %D expansions are available with Postfix 2.2 and later.

%[1-9] The patterns %1, %2, ... %9 are replaced by the corresponding most significant component of  the
       input key’s domain. If the input key is [email protected], then %1 is com, %2 is example and
       %3 is mail. If the input key is unqualified or does not have enough domain components to satisfy
       all the specified patterns, the search is suppressed and returns no results.

       The above %1, ..., %9 expansions are available with Postfix 2.2 and later.

我认为你需要这个：

recipient_delimiter = +

在你的 main.cf 中
