archive.today had this to say about the issue:
2018-07-13T1545: yes, unlike other public DNS services, 188.8.131.52 does not support EDNS Client Subnet
2018-07-15T1958: "Having to do" is not so direct here. Absence of EDNS ...
This is the statement from the CEO & co-founder of CloudFlare on Hacker News in May 2019 about this issue:
We don’t block archive.is or any other domain via 184.108.40.206. Doing so, we believe, would violate the integrity of DNS and the privacy and security promises we made to our users when we launched the service.
Archive.is’s authoritative DNS servers ...
This is a very interesting question, and I've given it a lot of thought.
The one sentence answer is "because archive.is blocks DNS requests from Cloudflare's datacenters". That of course leads to the core question: "why?".
This behavior of archive.is is especially intriguing to me because archive.is seems to have an emphasis on being anti-censorship and ...
First, changing MX records wouldn't be done in Gmail, it would have to be done through your DNS provider (the service hosting your domain's zone file). That's most likely the place you registered your domain name but not necessarily, that depends on how you decided to set things up.
Second, even if you change the MX records of your domain and point them to ...
It's strange that you don't receive any NDR. You should also check logs of your mail-server.
The process of removing yourself from blacklist is pretty well explained in here: http://www.rackaid.com/resources/hotmail-blacklist-removal/ (this post is quite old, but not much actually changed since that time...)
Be ready that you'll need to spend some amount ...
Login to your account.
On Tab Domain Settings, there's a sub section called "Domains"
There, you click on "Advanced Domain settings", which will take you to your domain services(ex: godaddy) console.
I am not sure if you could change the DNS settings right from your Google Apps console. I never saw that option. As far as I remember, this option was ...
I contacted Google Apps, this is apparently a known bug. The validation seems to fail. Actually, it fails in all cases. So this is not a relevant indicator.
If you can send and receive emails from your domain alias, the validation has succeeded.
A CNAME is just an alias used by the browser to look up the IP address of a website - the server still only sees the original address (e.g. docs.example.com). In fact, all YOUR-GITHUB-USERNAME.github.io domains are just CNAMEs that point to the same DNS record.
This means when a request comes to GitHub, there is no way to tell from the header which GitHub ...
I found a good work around;
Create a REDIRECT (NOT CNAME) (as mentioned above) to https://mail.google.com/a/YOURSUBDOMAINNAME/&ss=1
Then you will have the same functionality and the right login as your primairy domainname.
This isn't currently supporting, but there may be work-arounds.
According to Google's help site:
Custom URLs work only for user accounts in your primary domain. Users who sign in with a domain alias address or an address in any other domain associated with your Google Apps account must instead access services using the default URL. (See other ...
Yes you can do it by adding entries to the /etc/hosts file in the same manner as you do in windows.
This can be done on a jail-broken iPhone relatively easily (either via SSH or a terminal app on the phone) and similarly from rooted Android. As far as I;m aware it can't be changed from Application code.
Another option you might want to look into is ...
This is probably just an issue with the side of the recipient's. I don't believe that you can do anything on your part except wait. Google automatically resends the mail whenever possible, so your email will end up on your recipient's inbox eventually.
If it is urgent, do use other means to contact the recipient (like using the phone, etc).
This would be near-impossible to accomplish. It is easy to set up a GAE app on a custom domain, but it seems the OP has some more specific requirements.
The xxx.appspot.com domain can certainly be translated to an IP address, but GAE's servers will not be able to respond to requests by IP address. It has to know which app you are trying to access, and ...
The documentation at the link that you provided says:
Your other email provider has to provide authenticated SMTP support for you to use this option. We'll use TLS by default, or SSL if you enable it. Many email services that provide POP or IMAP support also offer authenticated SMTP support, and you can likely find your SMTP server configuration ...
You have two options.
1. Using only email forwarder
You can add a mail forwarder for that one email address to google apps mail address on test domain alias.
If you add your_domain.com to google apps, Google will provide you with your_domain.com.test-google-a.com as a test domain alias
Lets say you want email1@your_domain.com to be on google apps, don't ...
There's no reason why having two A records won't work as you describe it, but the instructions are good practice because you should decide which is the canonical address of your site, www.domain.com or domain.com and redirect to the canonical name. Using two A records will make the site visible at both addresses.
Apart from the aesthetic considerations, ...
The proper way to do it is to add an A record pointing to 220.127.116.11 and to also add a C name record pointing to the Github user account 'username.github.com'
The Github pages snippet (see image posted in OP) created by Zerigo is out of date.
I don't know how to check but you can get sending fail mail bounce back to sender email address if IP/domain is black listed.
If your server/IP black listed than you can get the domain white listed from Microsoft support link ,
This link really work check here:
Sender Information for Outlook.com Delivery.
Although this was not supported by Google Apps in the past it is now supported!
Note the Customize a Google Apps service address page no longer lists the inability to use secondary domains in the Requirements and restrictions section. I have personally used it and it works 100%.
I think the problem should be answered via this link： http://www.google.com/support/a/bin/answer.py?answer=182452
Google Apps treats add-on domain as a sub-organization than an independent firm whatever it's set as alias or separate domain.
Regarding this, I think you have to register Google Apps separately for each domain.
Also, I think there is a way ...
