spf

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? This is so I can implement SPF within my mailing App to verify a user has authorized our servers via SPF DNS records to send mail. 回答1: Look at the libraries here: http://www.openspf.org/Implementations None are in PHP, but they are in other languages, so if you get stuck creating a validator according to the publish standards, you can see how

问题 We have noticed that a lot of our emails are falsely flagged as spam. Upon reading online, it seems like a good way to solve this issue is to add an SPF record into the DNS, so we added a TXT record with this content: v=spf1 a mx ip4:162.123.189.010 include:_spf.google.com include:bluehost.com ~all Bluehost is our host provider, 162.123.189.010 is our VPS IP address from blue host, and _spf.google.com is needed because we send/receive email using GMail. After running a test on Google's MX

问题 I have 3 SPF records: "v=spf1 include:spf.protection.outlook.com -all" "v=spf1 a ptr include:authsmtp.com ?all" "v=spf1 a mx include:spf.mtasv.net ~all" How can I merge them all together into one txt record? 回答1: The merged record would look like this: v=spf1 a mx ptr include:spf.protection.outlook.com include:authsmtp.com include:spf.mtasv.net -all You'll have to decide which of the all mechanisms you want to use, since you can only have one in a SPF record. I have included the -all since it

问题 Firstly, I AM NOT A SPAMMER :) I am a legitimate developer, working for a company who is currently developing an enewsletter sending system for our clients. Now, we sent out a campaign for one of our clients to 80k solicited emails, and we got a huge amount blocked due to spam, even though our client has used ymlp.com to send similar campaigns to the same mailing list in the past with no problems. I have stumbled across a few nuggets of information such as: How to send 100,000 emails weekly?

问题 What would be the correct SPF record to use for both Amazon SES and Google Apps together: Google Apps says they want you to have the tilde "~" in it: http://support.google.com/a/bin/answer.py?hl=en&answer=178723, but most other examples have a dash "-" instead. Amazon wants: "v=spf1 include:amazonses.com -all" Google wants: "v=spf1 include:_spf.google.com ~all" We currently have this, combining both together: TXT "v=spf1 include:amazonses.com include:_spf.google.com ~all" SPF "v=spf1 include

问题 I have a web app which needs to send emails to clients 'From' staff email addresses. What's the best way to prevent my messages from being flagged as spam? For instance, if I own charles@gmail.com, I'd like to be able to send mail "From" that address with PHP in my App, without getting the "This message may not have been sent by...." message. Right now I'm just using the mail() function within PHP, with Headers for the From, Return Path, and X-Mailer variables. I'm generally pretty confused

问题 I've a small SaaS where each client gets a subdomain (stackexchange.my-saas.com) I've a mailgun account where my main domain is setup and I've created a wildcard SPF record in my DNS and if I add additional domains to my mailgun account with a subdomain, they all verifies correctly. My question is, do I need to add every new clients subdomain as a new domain in mailgun when I have the wildcard SPF record set or can i "legally" just create a from-address for each new client so the header of

问题 In my setup I have a website (example.app) hosted on Heroku. Then, I use Sendgrid to send emails from the Heroku server to our users that forget their password. The email is registered using Google's Gsuite. So I also send emails from the Google servers. The from email is: <Appname <noreply@example.app> So I thought these should be my DNS records (note I don't have an A-record): CNAMES: example.app CNAME "example.app.herokudns.com" www.example.app CNAME "www.example.app.herokudns.com" SPF:
