我试图让我的Postfix和LDAP后端接受配方分隔符（又名地址扩展名）。
邮件系统的其余部分工作正常，但是当收到带有扩展名的电子邮件（例如[email protected]）时，它会尝试查找针对LDAP服务的“coops + test”并失败。 显然这是错误的，它应该删除“+testing”部分。
在我的postfixconfiguration中，传递给LDAP服务的string是“％s”，下面是一个示例行：
accounts_query_filter = (&(objectClass=MailAccount)(mail=%s)(accountActive=TRUE)(delete=FALSE)) 是否有一个后缀variables代表电子邮件帐户减去扩展名？ 我在这里find了一个类似的post，但没有实际的解决scheme。
根据手册ldap_table（5）的可能性是：
%% 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.
我想你需要这个：
recipient_delimiter = +
在你main.cf中
