Hi Kemical, Thanks for the help.
I've done some research and reading into clients, and as you would expect, Thunderbird came up frequently. So, yes, I've considered Thunderbird, but it didn't make it to the top of my list. As to why it's not at the top of my list...
When you read reviews about anything (software, car tires, barbeque grills) written by the general public, what I normally find is that you usually have about an equal number of people who thing something is the greatest ever and those who think it sucks hard. The extremes generally cancel each other out and then you have everyone else in the middle. What you have to do is gauge the trends of the people in the middle to figure out where the entity being reviewed actually falls.
Problem is there seem to be way more people who dislike Tbird than like it. Completely subjective, but that's what my limited research lead me to believe.
So, I took a look at that mozillazine KB page you pointed me to, and I'm not sure I understand the details. They talk about the Import Wizard being able to bring everything in:
If you are starting up Thunderbird for the very first time, the Import Wizard will pop up, and you can then select the "Outlook Express" option to import your mail, address books, and settings.
That sounds to me like it will read .dbx folders in directly (which is what I want), but then they get into "Advanced alternatives":
Use either DbxConv or dbx2mbox to convert the .dbx files used by Outlook Express to mbox files. Then import the mbox files using the ImportExportTools extension.
So the question is, if thier import wizard does what they say it does, then why would you need "advanced alternatives"?
