SMTP Rescue Diagnosis through Wormly.com
Every craftsman, technician, and engineer knows the satisfaction of having access to the right tool for the job. On a recent task, I've been integrating Google's cloud messaging with on-premise hardware. It's surprising complicated, with the added constraint of advanced security controls that prohibit me from using any of my normal network tools.
What's been a challenge, is to confirm SMTP routing from different outside sources, through Google Message Security (GMS aka Postini), and into the on-premise systems. When I'm inside the customer site, I'm blocked from any outside access, and when I'm off-site I have no management of internal systems. In the past, I've used a Domino server (which has just the best admin console) for lots of testing--but the ports are blocked at my client site.
One of my work-arounds, has been to use an AT&T AirCard (which relies on Cingular for the data connection). Now, I can be on-site with my laptop connected to the outside. I can limit my inbound traffic by IP restrictions, and run the Swiss Army Knike for SMTP (SWAKS) scripts. Works great. Except, when it doesn't.
Sadly, the AirCard connectivity is not very good (it's because of the facility location), and worse, it periodically resets DHCP, giving me a new IP (and now I'm locked out from the external connection and have to reset all the trusts).
By accident, I found Wormly, a very powerful web service providing SMTP testing (and more). It allows me to send SMTP packets from an outside connection, and I can set the IP for the receiving server (because I'm usually bypassing MX records). Even cooler, is that it shows the console activity. For instance, if I test whether or not something like IP Locking is working, I can read the failure in the Wormly console dialog. This is critical, because there won't be any Non-Delivery Failures generated from this error.
Wormly is a terrific network tool, and belongs in every network engineers set of bookmarks.
For years it seemed that every vendor could have manuals, missives, and tomes stacked at the local Borders--except for the anemic showing of Lotus Domino. IBM would point to the ocassional RedBook (again, never seen on a booksellers shelf). And now ? Well, my local Borders is closing, RedBooks have been replaced by up-to-date wikis and PACKT Publishing is on a tear with the coolest in technology, including Lotus.
