Joe has a 2009 iMac with a bunch of emails on it, dating back to 2003. He wants to know how to open them in another email program, along with the contacts as well? Leo says it varies according to the email program you use. Leo says that since Apple Mail exports to MBox, you can open that format into just about any other email client. You can even open them in a text editor to see what's in it. Apple Mail will import them easily, and Thunderbird should be able to as well. Leo also recommends using SuperDuper to back them up.
Doug has three different Windows 10 computers, but programs operating differently on all three. Incredimail has gone away, and so he tried Mozilla Thunderbird. Leo says that it probably has to do with how each computer was set up, which prompted POP3 instead of IMAP. You'll need to uninstall Thunderbird and reinstall. You have to use an IMAP server and port. What Leo suggests exporting the profile on the right Thunderbird computer, and import it into the other two.
Sam has worked hard to minimize his bandwidth by turning off images in his email account. But it the image still flashes briefly, what gives? Leo says that what Sam has discovered is that while the email account isn't displaying the image, it's set to display your email as HTML, and that means it's still downloading them, and that can trigger a virus or exploit. What you need to do is use an email client that only downloads the ASCII text email and not display emails in HTML. That will prevent it. Thunderbird is free and is very good. Turn off HTML and image loading.
Ron is having issues with Thunderbird after a recent security change that is causing him issues. Leo says that Thunderbird has largely been abandoned by developers, who are simply not keeping it up. He may want to check his IMAP and SMTP addresses to make sure they are configured correctly. He should double check how to properly log into it, and what port he'll need to use. His ISP can help him with that.
Mike uses Thunderbird with POP3 and wonders if he should use IMAP. He doesn't know anything about it, though. Leo says that Thunderbird is the best email client out there and Leo uses IMAP with it. POP (post office protocol) will download his email and then remove it from the servers. IMAP, by contrast, will allow him to see the email and keep copies of it on the server. This is beneficial because people use more than one computer and mobile phone.
Pauline is concerned that with Verizon buying AOL, her Yahoo Mail will go away. How can she back it up? Leo says that using POP3 mail is essentially backing up her email to her hard drive because it downloads the email directly to her computer. So it's already backed up.
Chris just bought the Windows Surface Pro 4. What's the best email client for it? Leo isn't fond of Microsoft's default, which is Outlook. He prefers Thunderbird, which is free from Mozilla. It stores email into a standard text based format and also provides calendar capabilities through the Lightning add-on.
Diane wants to be able to save her email messages from Yahoo Mail locally to her computer as a form of backup. Leo suggests using an email client, and he recommends Mozilla Thunderbird. This program stores email in a very standard mbx, or mailbox format, that other programs can also understand. That way, if Thunderbird were to go away, Diane would be able to easily be able to still look at her messages with any text reader.
Frank is ready to finally get rid of AOL and wants to know what's a better alternative; especially for email. Leo likes Gmail because he can sync all of his devices thanks to the IMAP email protocol which keeps all email at the server level. Frank can just use the webmail version or he can use an email client like Outlook. Mozilla has one called Thunderbird.
Chris uses Carbonite and wants to know if there's a better email program than Outlook. He also wants to know if that would make it better for backing up. Leo says that Outlook puts everything in one giant .pst file, but Mozilla Thunderbird breaks it out into individual files. Carbonite or any backup company just will backup whatever files he has, it won't care what program he's using. It's up to him to have it backup the right files. So as long as he backs up his Thunderbird Profile, he should be OK.
