Helping people with computers... one answer at a time.
I'm not sure what additional security you're looking for in Thunderbird. A secure connection is something that can be done in either program.
I just switched to Thunderbird 15 email from Outlook 2010 for better security. In the process, I chose to retain my old email address. In order to get and receive messages, I needed to enter "None" for the security type for both outgoing and incoming servers, and also enter the exact same ports for those servers for Outlook. Somewhere along the line, when entering the old ports, a warning came up about my understanding the risks, and I chose to continue with those ports and "None" security settings. With my present setup, would you say that Thunderbird is still significantly more secure from viruses, phishing, etc than Outlook 2010?
In this excerpt from Answercast #56, I look at the merits of security in Thunderbird vs. Outlook.
So I've never really considered Outlook 2010 to be non-secure. I consider Outlook and Thunderbird to be relatively equivalent on the security scale.
That's not to say, "Outlook Express." Outlook Express is a different program from Outlook, and I think that everybody should be migrating away from Outlook Express. But Outlook 2010 is a fine email program and I really don't have any security issues with it at all.
Now, that being said, the security that you're discussing here... I'm not really sure what it is you're trying to avoid.
The way that your computer connects to your ISP is not something that would change simply by changing email programs. If your ISP requires a certain type of connection on a certain type of port in order to access your email, that's independent of the email program you're using.
In other words, yes, absolutely. The settings that you would be using in Outlook would be exactly the same settings that you would be using in Thunderbird. There would be no difference. Those settings are determined by your ISP or your ESP (your email service provider).
Now, that being said, you might want to look into your email service provider and see if perhaps they do provide you the opportunity to make secure selections.
The difference in the connection that we're talking about here is that usually, for example:
Now, there are usually alternatives.
So what happens is when email is sent on those ports, the email, (the connection itself) is actually encrypted between your computer and the email server. That means that anybody snooping in on your ethernet connection or your Wi-Fi connection would only see encrypted noise. They wouldn't be able to actually see the messages that are going back and forth.
But again, those are functions provided by your email provider and they are functions that you could use just as equally in Outlook as you could in Thunderbird. The email program makes no distinction between the two; it simply needs to be configured correctly to use whatever it is your email service provider is providing.
Other security beyond that? I'm not really sure what it is you're looking for. Email programs certainly have a level of phishing protection (both of them do these days). Viruses... kind of, sort of, maybe?
The choice that you're making here, the migration from Outlook to Thunderbird, while I laud it (because I like Thunderbird as an email program), that liking has nothing to do with the security merit differences between the two. I think they're both pretty secure.
I happen to like Thunderbird as a simpler interface. It's a relatively
faster program. It uses a storage model that I prefer. But I'm not really sure
what additional security that it is you're looking for here. The connection
that we've talked about, the connection that you've brought up, is something
that could be done in either program.
