Hi there,
I am at my wits end. I have been on the phone to Symantec, I have been on live chat, I have read article after article and Symantec seems to make it very difficult to resolve this issue, or even help at all. This is now effecting my business opportunities. I am running an email account through G-Suite hosted at HostGator. I have changed the SPF records to include all from spf.google.com. I have added a DKIM record. I have added a basic SSL to the domain. Hostgator can't help me. Gmail can't help me and Symantec refuse to help me because I don't own their software.
The error message is: "553 Message filtered. Refer to the Troubleshooting page at http://www.symanteccloud.com/troubleshooting for more information. (#5.7.1)"
I have gone to the support page and have tried everything else to fix this with no resolution.
I. Check if your sending IP is on any spam lists, search for “spam database lookup”. You are looking for any 3rd party lists that may have received spam from your mail server. If your IP address is on any of these block lists, please make a removal request as soon as possible, once removed please retry sending your mail. - The IP is not on a Spam List
II. Ensure your mail server is not open relay, search for “Email Open Relay Tester” and choose from any number of testers. - The mail server is not on Open Relay
III. If your internet line is provided by DSL or Cable that shares IP’s with residential users, please ensure your mail server sends to your ISP’s smart host instead of direct to the internet. This reduces the potential of your email being detected in error as coming from a Trojan infected home user machine. - Happens regardless, Mobile, Work, Home network.
IV. Ensure the email you are sending does not contain any spam content (i.e. forwarded spam or ‘spamvertised’ URL’s). - Tried without any links, HTML, Plain Text, No attachments, Everything.
V. Ensure your mail server is configured correctly. - According to both G-Suite and Hostgator, Yes.
VI. Ensure you have no virus infected machines on your network that are being used to send spam through your mail server. - No malware detected by SiteLock or Hostgator
VII. Ensure you have no exploitable web scripts on your web servers that could be abused to send spam. The most commonly used one is PHP contact scripts which spammers use to abuse the PHP “mail()” function, giving them free reign to send what they want. - Nothing
VIII. Make sure any ‘opt-in’ newsletters contain an ‘opt-out’ link to be certain users can easily unsubscribe. If the problem persists, please contact the recipient by other means and request that your email address be added to their Symantec Cloud approved senders list. - I don't send newsletters at all.
If the problem persists, please contact the recipient by other means and request that your email address be added to their Symantec Cloud approved senders list. Additionally, a legitimate email which has been incorrectly given a verdict of spam can be submitted to Symantec for analysis and filter review. Please review the False Positive submission article to submit a false positive message for analysis. - I have contacted all companies (banks) that I am having issues with and my domain is on their Whitelists and the problem still persists. Furthermore I have submitted multiple false positives with NO response. I have followed the instructions on sending as an attachment but regardless of how I do it, it is still a .eml or .msg file and there is no information anywhere on how to change this.
Why is is that no one can tell me WHY this is happening to my emails, Symantec is filtering them so why will they not help me solve the issue? I am whitelisted at the clients end in their symantec admin settings yet my messages still get bounced. Please for the love of god just help me fix it.
