That's fairly common for residential service. More ISPs are doing so, and it's good practice for limiting spam. If you run an SMTP server, ask your ISP for a business-class account. You'll pay more, but you won't have filtered access. I don't think there's any other way for you to run an MX for your domain on one of their lines. If you want to allow users to send email through your server, you should definitely run an SMTP server on port 587. It should require SMTP AUTH for relay privileges. You will probably need to configure your server to use Verizon's SMTP servers as "smart hosts" to relay your mail. > More recently, recipients with @verizon.net cannot receive emails from our > hosted domain names.

You did publish an SPF+ record for brama.com. What leads you to believe that this is the source of the problem? -- users mailing list users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines
