I have binned Thunderbird. It's constant changes to things I don't want - tabbed mails being one and swallowing digitally signed pdf invoices being another. I complained about the invoices, but the complaints/debugging system was so obscure I gave up. It is designed for professional software testers, not users. I tried Pegasus Mail. I binned it after 5 hours struggle as impossibly complicated to set up with 6 accounts (yes I have 6 - actually 7 email accounts). How to set up an email account is on page 129 of the manual. I ask you! :-( I am now trialling Postbox ($30 payware), So far Day 4 of 30, Postbox is looking good - easy to set up and if you click on an account folder before sending an email, it sends emails from that account rather than always from the default address unless you remember to change it - which is what Outlook does and which creates confusion among the recipients. Apart from that, most comments I have had during my research is that Outlook is hard to beat. My reason for not using Outlook is that my version 2000 won't work with Windows 7 on my new laptop, from where all my emails are now run except this one (my work one). Peter
