Email Delivery Failures Reports: Real-time and AutomatedFriday, November 18th, 2011
Sent Email Delivery Tracking Reports Have ArrivedMonday, November 14th, 2011
Our Support team fields this kind of question on a daily basis. Usually the message never arrived because the address was misspelled, the message was never actually sent, or it was filtered by the recipient’s servers. There are many other reasons why messages “disappear” as well. Customers sending email to mailing lists (e.g. those using LuxSci High Volume services), often want an easy way to find out what addresses failed and why, and to know for sure what messages were delivered properly. Now, LuxSci customers can see for themselves exactly what messages have been sent and track them to learn what the disposition of any particular message to any recipient is at any time. The new reporting tools are fast, easy, and no longer require the assistance of Support.

An email server, however, does lots of different things in addition to sending outbound email. It may allow checking of email via POP or IMAP, or checking your address book using LDAP, or other things. So, when your email program connects to the server it has to specify what it wants to do (i.e. send an email). It does this by connecting to a numbered “port” on the server. Port number “25″ is the Internet standard for “regular outbound email”. However, because port 25 is standard for outbound email, many ISPs, wifi networks, hotels, airports, and other locations that provide Internet access will arbitrarily block any connections to servers (except perhaps their own) on port 25 in order to stop spammers from using their services for the sending of spam, viruses, or malware and to prevent their IP addresses from being black listed.

Why Cloud Servers are Bad for Sending EmailThe IP address spaces used by the major public cloud vendors (i.e. Amazon, Rackspace, etc.) for their cloud servers are well known and are generally black- or gray-listed by anti-spam systems. Additionally, many of the IP addresses in use by these systems are already “polluted” from previous abusive use by spammers. When you set up a new cloud server, you could be easily assigned a “bad IP”. Even if you do not inherit a bad IP reputation from the previous user(s) of your new IP, your server is still in the general set of IP addresses of the cloud and thus considered a possible spam source.

Sometimes you’ll get an email bounced back to you saying that your email server is blacklisted by Barracuda due to IP reputation even though you know your server is not blacklisted. An example of one such bounce is listed below. 
Transactional bulk email messages are those that have mostly similar content and which go out to recipients as needed. These may be to the same set of recipients over and over, or to new recipients every time. What makes them “bulk” is that the number of messages sent can be quite large … much larger than you could hope to send through a normal business email account.
Generally, when you send an email message and it fails to be delivered, you get a “bounce back” to inform you of this. This delivery failure notification system is inherent in the way email works and does a good job, in general. However, it has some serious limitations:
What happened to that email message that I sent 3 days ago? It “never arrived!”.
Many major Internet Service Providers (e.g. AOL, Hotmail, MSN, Comcast, etc.) have FBLs “feedback loops” for reporting SPAM complaints by their users. I.e. if a user “marks a message as Spam”, information about that message and the fact that it was considered “Spam” by the recipient can be sent back to the originating email server, for example LuxSci.
LuxSci is pleased to present our latest feature for improving the secure email experience for Microsoft Outlook users — the new SecureLine Plugin for Outlook!
