I need a solution
Emails from my company are getting bounced with the "server-15.tower-179.messagelabs.com #553-SPF (Sender Policy Framework) domain authentication 553-fail. Refer to the Troubleshooting page at 553-http://www.symanteccloud.com/troubleshooting for more 553 information. (#5.7.1) " error. I do have a valid SPF record that was working fine until last night or maybe first thing morning. Has anything changed - requirements/format of the record?
v=spf1 mx a mx:mail.mydomain.net -all
