An increasingly large number of our customers are using Gmail or Google Apps and almost all of our OSS/BSS mail is getting spam filtered by Google. Among others, these e-mails include invoices, order confirmations, payment notifications, customer portal logins, and tickets. Almost anything we send to customers on Google ends up in their spam folder.
Erik, Do you send marketing information to your customers from the same IP addresses as you send your invoices? Have you checked the source IPs against the RBLs with, e.g. http://rbls.org/? What about the source IP of the specific machine the originates the invoices et. al? Is the invoicing machine also in SPF? One of the companies I do business with accidentally excluded their billing mailer from the SPF record. Have you sent copies of the various types of documents to a mail server running Spam Assassin in order to see which qualms Spam Assassin flags? Careless mistakes with the headers or the clock can get your message flagged as spam. Even something as simple as ALL CAPS can get you flagged. Have you added your invoicing mailer, the one you can guarantee sends no marketing materials, in to the whitelist at http://www.dnswl.org/? Regards, Bill Herrin -- William D.
