SMTP timeout after sending data block… What’s The Issue?

Thursday, September 13th, 2012

This type of mail server to mail server SMTP failure is usually accompanied by log message like the following:

“SMTP timeout while connected to xx.xx.xx.xx [xx.xx.xx.xx] after sending data block (8189 bytes written): Connection timed out”

This type of failure could arise from any number of network connection issues, firewall packet inspection, a security application, or a virus scanner on the local mail server.  However, in every case we have encountered this it has been due to an issue with security systems on the receiving system, typically on the router itself.  For the most part, this failure only occurs when the recipient’s scanning system is processing emails with attachments (regardless of size) and it reaches a point where it fails/freezes.  After that, the recipient system stops accepting new SMTP data and after a predetermined time, the SMTP connection then times out.

OnlyMyEmail Stops More Spam 8 Competitions In A Row

Monday, April 16th, 2012

For the eighth time in a row, OnlyMyEmail has blocked more spam than any other email filter in the Virus Bulletin VBSpam Challenge.

Once again, OnlyMyEmail’s MX-Defender accurately filtered out more spam than all other competitors tested, missing just 4 spam emails out of 146,121 total. This represents a spam capture rate of 99.997%.

By comparison, the next best capture rate was SpamTitan which not only missed 47 spam emails, but also inadvertently blocked 600% more legitimate emails, known as false-positive results.

The average “false-negative” rate among the other 21 filtering systems tested was a whopping 293 missed spam messages and the median was 176.

The results from Virus Bulletin’s VBSpam Challenge have proven, time and again, that OnlyMyEmail’s MX-Defender is decisively superior to any other spam defense available today, including hardware appliances, software programs and other Software as a Service (SaaS) solutions solutions as well.

Quoting from the full VBSpam review:

In this test, OnlyMyEmail missed fewer than one in 36,000 spam messages. After several exceptional performances like this, we’ve almost stopped being surprised and thus it is good to note that many users do not even receive this much spam in a full year!

The full list of competitors to date, includes: AnubisNetworks, BitDefender, CronLab Anti-Spam, FortiMail, GFI MailEssentials, Halon Security, IBM Lotus Protector, Kaspersky Anti-Spam, Libra Esva, Mailshell, McAfee Email Gateway, McAfee EWS, McAfee SaaS, Messaging Architects M+ Guardian, Sophos Email Appliance, SPAM Fighter, Spamhaus ZEN+DBL, SpamTitan, Spider Antispam, SURBL, Symantec Messaging Gateway, The Email Laundry, Vade Retro, Vamsoft ORF, and ZEROSPAM.

Email Protocols & Settings, Your Best Choices

Tuesday, April 3rd, 2012

Now that email is everywhere, not only on computers but on phones and tablets, even casual technology users need to understand their email configuration options.

Not only can understanding your choices make managing your email easier, but your efficiency, privacy and security can be greatly enhanced as well.

For receiving email the most common protocol is old good old-fashioned Post Office Protocol (POP3).

Using this protocol any device can download messages from your email hosting servers. If you use multiple devices you might want to configure each device “leave mail on server” for just a few days in order to allow each device enough time to download a copy of each message. Leaving too much mail on your email server for too long can slow down your access and also exceed your email storage quota.  For more on this subject, see: Should I Leave Messages On The Server?

What if someone says they sent me a message but I didn’t get it?

Thursday, August 11th, 2011

We commonly receive questions from users who tell us an expected email has not arrived, and they don’t know how to go about finding it.

Fortunately, with proper information and the right approach, it’s not really that hard to track down missing email messages.

Like snail mail, email follows a path from the sender to the recipient and problems can arise along the way.  When a package or letter hasn’t arrived, it doesn’t make much sense to start yelling at the mail carrier; instead you have to start at the beginning and follow the message from point to point.

Following the chain of possession, the most common causes of missing email are as follows: more »

New Skype Has Been Releases ! Upgrade Now

Saturday, July 16th, 2011

Mailboxes are now receiving fake Skype upgrade spam sent from hijacked Rhapsody.com mail servers.

The current campaign arrives as:

Subject:     New Skype Has Been Releases ! Upgrade Now
From:     “Skype” <newsletter@news.skype.com>

In an interesting twist, the spammers involved appear to have hacked and are in control of Rhapsody.com mail servers as the samples we’ve reviewed so far are actually from:

  • mta900.e.rhapsody.com ([63.211.90.40]
  • mta902.e.rhapsody.com ([63.211.90.42]
  • mta903.e.rhapsody.com ([63.211.90.43]
  • mta904.e.rhapsody.com ([63.211.90.44]
  • mta905.e.rhapsody.com ([63.211.90.45]
  • etc., etc.

Apple Store Order Notification Spam

Friday, May 27th, 2011

Were seeing a fair amount of bogus Apple Store Order Notification spam emails that are sufficiently confusing to end users that they are frequently resending these to themselves after our filtering initially blocks them.

The emails present themselves as:

Subject:     ID:921-818692 Apple Store Order Notification
From:     “Apple Store” <Store@apple.com>

The “Order ID Number” for each spam can be random, which helps these spam emails to appear legitimate and also to help evade many spam filters.

The sending address is spoofed, and the emails themselves are quite simple:
