The other day, a client wrote in to tell us he appreciated how we take such good care of his email compared to some other hosts. That was nice to hear because while mail is one of those things that users just expect to work, it gives hosting companies fits including us.
As a web host, we maintain complex networking systems along with a variety of web servers, DNS servers, database servers, file servers, monitoring servers and backup servers just to keep your website up and running smoothly. In addition, we maintain a variety of servers for mail including servers for sending mail, receiving mail, evaluating and tagging mail for spam, storing mail and archiving it.
Email is tricky because there is so much that can go wrong with it. It wasn't always like that, though. Email was one of the first Internet protocols, having been invented to send plain text messages in 1971 just two years after the net got started and 19 years before the world wide web turned up on the scene. There were no hackers, no viruses, no spam, no phishing, no attachments... and few problems.
The first fly in the ointment came in 1992 when the first Mime attachment was sent. Before that, files were shared using FTP, Small ones might have been encoded into text, added to an email message and decoded upon receipt, but that was something for tech nerds, not the everyday Joe. Mime attachments were created for him. So if you ever wondered why you can't send huge attachments in email, it's because email wasn't originally designed to handle them at all.
Sending to Multiple Recipients
Abuse of email has caused hosts to come up with a great many tools and techniques to minimize it and protect customers without making it extremely difficult to use. One of those is to limit senders from sending the same message to a huge list of recipients. If you host limits this practice, you can use mass email marketing systems like eBlast111 or the eBlast tool built into our Build111 CMS website creation tool. These systems are designed to avoid email abuse and have a good reputation with recipient email systems.
If you haven't already created a nice secure email password, stop reading and do it immediately! If you don't have one and your email account gets hacked as a result, spammers can send tons of spam from your account and get the IP address of your mail server blocked. This generally effects everyone on your mail server including you.
How Email Works
We thought it might be fun to try to identify all the potential points of email failure in order to demonstrate why email is not easy to keep running smoothly and why it can be hard to diagnose problems when they arise. Below is what happens in a typical mail process like ours with the steps as the main bullets in bold and potential problems indented for each step.
From a user perspective, you craft your message in your mail client (Outlook, Thunderbird, Webmail like Gmail or others). Then you hit "Send" and figure you're done. But from our perspective, that's just where the fun starts...
So by my count, there are 31 potential things that can go wrong with email identified here. I'll be we missed a whole lot of others, so if you can think of some more, add your comment.
