not an outlook replacement, AN OUTLOOK KILLER

As a former user of Microsoft outlook(at work and at home) and until recently a user of Thunderbird, I’m so happy to found em client, free, superb and beautifully designed program.
It is not an outlook replacement, it is an outlook killer.
I intend to recommend it to everyone, both for personal usage and for enterprise usage.

Yes i do agree on that still minor enhancements like

when you receive reading rec you have 0 byte .dat attachments
when you receive email with signatures all the signatures are in the attachments

from my side this some time annoying

thanks and keep the good work
