Threaded Notification Emails

We have a new feature to make it easier to keep track of email notifications. Previously, each email notification started a new email thread or conversation, even if it was just reported that a formerly reported down check was now up. Now, our Business and Provider plans have the option of grouping these emails together through Branding. If you got a “Host Down” email, for example, you can set the “Host Up” message to be sent as a reply to the original email. This feature was made with the goal of keeping track of email notifications easier.

On the back end, we’ve added message references to our emails so your email client knows that the “Up” message is related to the “Down” message.

However, not all email systems will identify that messages are related to each other just based on the “reply-to” and “references” ID’s.  For gmail and some other email services, in order to enable this feature,  you’ll need to adjust your NodePing settings to make your up and down email subject lines identical.  To do this, first login to your NodePing account. Then go to the Account settings tab, then the Branding tab under it.  All you need to do to receive your up and down emails on the same thread is set their subject lines to match. Scroll down to Up Notifications: Email “Message Subject:”and set it to match Down Notification: Email’s “Message Subject:”, or vice versa. Or, you could set their subject line to be something else entirely; the important thing is that they are identical.

By the way, the notification branding lets you do a lot more besides just make the subject lines match for message threading.  You can customize what your notifications say and what information is included.  There’s more information about this powerful feature in our documentation.

We hope you find this feature helpful. If you haven’t tried NodePing yet, you can get a free fifteen-day trial here. If you have questions or comments, email us at support@nodeping.com.

RBL Monitoring

What better way to top off our email monitoring enhancements than with a new check type! We’re happy to introduce our RBL check.

RBL, or DNSBL, stands for “Real-time Black List,” and is used to publish the addresses of computers or networks linked to spamming, malware, or other abuses which system administrators may want to block from accessing their networks.

There are hundreds of RBLs in existence, which use a wide array of criteria for listing and delisting of addresses. These may include listing the addresses of zombie computers or other machines being used to send spam, listing the addresses of ISPs who willingly host spammers, or listing addresses which have sent spam to a honeypot system.

If the IP addresses of your servers appear on these RBLs, there’s a good chance you’ll have difficulty interacting with networks that subscribe to these RBLs. For instance, if your SMTP server is listed, you’ll likely be unable to send email to the systems that use the RBL you are listed on.

You can use our new RBL check to ensure that your servers aren’t listed and to receive notifications if they do get listed, allowing you to quickly take steps to remove your addresses from those RBLs. You can find more details about which RBLs we check and how to set them up in our RBL Check documentation.

Adding RBL checking to our already robust email monitoring checks for SMTP, POP3, and IMAP4 will help you sleep at night knowing that email is flowing as it should be.

RBL monitoring checks are available to all NodePing accounts. If you don’t have an account yet, you can sign up for your free 15-day trial of our server monitoring service.

POP Monitoring Enhancements

As part of strengthening our email server monitoring solutions, we’ve added a bunch of new features to the POP3 check type. They nicely complement our recent changes to our SMTP and IMAP checks.

New features include:

  • Non-standard ports. Specify any port, not just POP default port 110
  • SSL/TLS support on any port – not just 995.
  • SSL certificate validation
  • SSL certificate expiration warnings – configurable to X days before expiration
  • User login verification.

More details about the new POP server monitoring enhancements can be found in our documentation.

These features are available to all NodePing server monitoring accounts today. If you don’t have an account yet, you can sign up for a free 15-day trial at https://nodeping.com.

Now, if you just had a way to monitor spam blacklists for your server ip addresses… RBL Check is on its way!

IMAP Monitoring Enhancements

On the heels of our SMTP enhancement release, we’re happy to add some significant features to our IMAP server monitoring check. IMAP refers to one of the two most popular methods of email retrieval, the other being POP. IMAP4 services are supported by nearly all email clients and its use continues to grow.

We’ve added the following enhancements:

  • Non-standard ports. Specify any port, not just IMAP default port 143
  • SSL/TLS support.
  • SSL certificate validation
  • SSL certificate expiration warnings – configurable to X days before expiration
  • User login verification.

It’s easier than ever to ensure your IMAP services are available and configured correctly. Find more information about the new enhancements in our documentation.

The new IMAP enhancements are available to all NodePing accounts today. If you don’t have a NodePing server monitoring account yet you can sign up for a free 15-day trial.

Next check on the block for more enhancements – you guessed it – POP3. I hear there’s a RBL check in the works too! Keep an eye out here on the blog for the announcements.

SMTP Check Enhancements

We’ve rolled out some important enhancements to our SMTP check that will help ensure your email server is running as it should be.

Added enhancements include:

  • Non-standard ports
  • SSL/TLS support including certificate verification and expiration warning
  • STARTTLS support
  • AUTH with support for PLAIN, LOGIN, and CRAM-MD5
  • Mail acceptance verification including open relay notification

The SMTP check will now not only verify that your email server is running but can also optionally check to see if your server is an open relay or properly accepting mail for a particular email address.

The new open relay functionality will test to see if your mail server will accept mail for an address that should not be allowed. If your server is an open relay, we will send you a notification.

It’s also important to verify that your email server is not rejecting mail that it should be accepting. There are many reasons an SMTP server may reject email. The configuration may have changed or a particular mailbox may be over its quota. This enhancement verifies that your server will accept messages to an email address of your choice and send you a notification if it is rejected.

We’ve added extensive SSL/TLS support including STARTTLS as well as certificate verification and certificate expiration warnings. Simply set how many days in advance of the expiration you would like to be notified and we’ll send you an alert, giving you time to renew and install your new certificates.

The new optional AUTH support allows you to verify that users can log in and send mail using industry standard PLAIN, LOGIN, and CRAM-MD5 AUTH mechanisms.

You can find more information about our new SMTP check enhancements in our documentation.

These enhancements are available now to all NodePing customers. If you don’t currently have an account, please sign up for our free 15 day trial.
