I understand that information I provide will be used for scientific reports and publications. |
What is the name of your email server software? Or, what is the name of your MTA? |
Are you using any framework, setup tool, or how to for your mail server? |
How many email accounts do exist under your operated infrastructure? |
How many emails does your system receive on average per day? |
Do you frequently update your MTA or associated plugins and mail filters? By update, we mean following the releases for the associated software and installing them regularly. |
If yes, approximately when did you last update your MTA or any of the plugins and mail filters? |
What security email protocols do you use? | Does your email server validate the sender’s SPF record when it receives an email? | What is the name of your SPF milter, mail filter, or plugin? In other words, which plugin or third-party library is doing the SPF validation when an email comes to your server? If your MTA natively supports SPF validation, please mark “MTA Native”. | Did you set up the SPF milter yourself? | When does your SPF milter perform the SPF resolution of the sender domain? | Did you change any of the default values in your SPF milter? (Like changing the default DNS timeout of SPF validation) | Did you change any of the following default values in your SPF milter? If yes, please indicate how did you change them. Otherwise, please select the "leave as-is" option. FYI, the RFC recommendation for total DNS lookup and void lookup limits is 10, and 2 respectively. | |||||||||||||||||||||
