非 Y 不嫁゛ 提交于 2020-02-27 08:25:19
简介 今天我们再来介绍 spf13 大神的另一个库 cast 。 cast 是一个小巧、实用的类型转换库,用于将一个类型转为另一个类型。 最初开发 cast 是用在 hugo 中的。 快速使用 先安装: $ go get github.com/spf13/cast 后使用: package main import ( "fmt" "github.com/spf13/cast" ) func main() { // ToString fmt.Println(cast.ToString("leedarjun")) // leedarjun fmt.Println(cast.ToString(8)) // 8 fmt.Println(cast.ToString(8.31)) // 8.31 fmt.Println(cast.ToString([]byte("one time"))) // one time fmt.Println(cast.ToString(nil)) // "" var foo interface{} = "one more time" fmt.Println(cast.ToString(foo)) // one more time // ToInt fmt.Println(cast.ToInt(8)) // 8 fmt.Println(cast.ToInt(8.31)

DMARC/SPF/DKIM not authenticating with third-party mail

问题 We recently implemented a DMARC record for our domain: "v=DMARC1; p=quarantine; pct=100; rua=mailto:me@mydomain.com" (quarantine 100% of non-authenticated emails and send aggregate report to "me") We use a third-party vendor to issue invites. The vendor sends email from invites@invites.vendordomain.com which is then sent through a mail relay "smtp3.mailrelaydomain.it". I also know that the mail relay uses a single ip address. That address is included in our SPF record: "v=spf1 ...[SNIP

问题 I host a spread of different domains that all use my (one) mail-server to send and receive mail. When sending mails, sometimes, my mail gets rejected by the receiving end, marked to the recipient as "suspicious" or simply heads straight for the spam folder. Also, on the inbound, I get a load of "return receipts" from random victims of spam, where one of my domain names has been used even though the mail never touched my mail server.

问题 I'm developing a web mailing app on Codeigniter PHP. I would like to know how to check SPF records are valid with PHP. Is there a PHP API to do this?
