使用PHP在IMAP服务器上查找具有确切电子邮件地址的电子邮件 [英] Find E-Mails with an exact e-mail address on an IMAP server using PHP

问题描述

我想连接到IMAP服务器，并找到所有发送到 [e-mail] 的电子邮件.我试过了:

I want to connect to an IMAP-server and find all E-Mails that were sent to [e-mail]. I tried:

$mbox = imap_open("{imap.server.tld/norsh}", "[e-mail]", "5ecure3");
$result = imap_search($mbox, "TO \"[e-mail]\"", SE_UID);

，但这还会列出已发送的电子邮件，例如到 [e-mail] .是否可以通过某种方式搜索完全匹配?

but this also listed e-Mails that were sent e.g. to [e-mail]. Is it somehow possible to do a search for exact matches?

推荐答案

简短的回答:不能.我在 RFC 2060-Internet邮件访问协议-版本4rev1 中找不到任何内容可以做到的.

Short answer: you can't. I didn't find anything in RFC 2060 - Internet Message Access Protocol - Version 4rev1 saying that it can be done.

但是，有一种解决方法.首先获取所有包含 [e-mail] 的电子邮件，然后遍历结果并仅选择完全匹配的内容.

But, there is a workaround. First fetch all emails that contain [e-mail], then iterate through the results and select only the exact matches.

$searchEmail = "[e-mail]";
$emails = imap_search($mbox, "TO $searchEmail");
$exactMatches = array();

foreach ($emails as $email) {
    // get email headers
    $info = imap_headerinfo($mbox, $email);

    // fetch all emails in the TO: header
    $toAddresses = array();
    foreach ($info->to as $to) {
        $toAddresses[] = $to->mailbox . '@' . $to->host;
    }   

    // is there a match?
    if (in_array($searchEmail, $toAddresses)) {
        $exactMatches[] = $email;
    }
}

现在您在 $ exactMatches
