This post is for any of my MessageLabs readers. I tried to send an email to my travel company today using my Gmail account (which I pop through Thunderbird). I got an NDR saying the following:
This is an automatically generated Delivery Status Notification Delivery to the following recipient failed permanently: address_removed@no_address.com Technical details of permanent failure: PERM_FAILURE: SMTP Error (state 12): 553-Message filtered. Please see the FAQs section on spam 553-at http://www.messagelabs.com/support/ for more 553 information. (#5.7.1)
I went to that link and I didn't see any FAQ's but I did see a list of bounce messages which I could click on for more information. I clicked on the first link (553-Message filtered) and followed the instructions.
- My connecting IP is not on any blacklists but the IP address does not have a reverse DNS.
- I'm pretty sure bullet points II through VIII don't apply to me, though if point III, V or VI are the problem there isn't much I can do about it. My machine does not have a virus, I can't control the mail server, and believe-you-me there isn't any spam content in the message.
I don't really want to add myself to my travel company's approved client list, I'd just like this to work. Thanks.
