Make Thunderbird a Better IMAP Client
Back in March I started looking for a new mail user agent, commonly referred to as email client. During the last few days I had a little time at my hands and I tried Claws Mail, eM Client, Postbox and Sylpheed. Regarding Postbox I went for the 30-days trial of the full version after I’ve compared the two editions (Postbox and Postbox Express). I set up a few IMAP and POP3 accounts and then I just used each client for a short time.
Once again, I’ll stay true to Thunderbird. To be honest, I liked Postbox a lot but it’s not that much superior to Thunderbird especially if you consider the add-ons situation. What I liked best about Postbox was the way they organized the accounts. That’s where Postbox really shines. So, instead of wasting more time with other clients I just went ahead and did what I wanted to do for a few years – I finally created a nice User.js to store some helpful preferences. I thought I’d share a few of the most important settings that I found with you:
// Thunderbird 3 adds a disk cache. Activate it to cache any remote content.
// Messages and attachments are now cached for IMAP accounts as well.
user_pref("browser.cache.disk.enable", true);
// Grant 50 megabytes of storage
user_pref("browser.cache.disk.capacity", 51200);
Now, let’s move on to the IMAP settings. Read more…
