I have tried several times to send an attachment using simple mail. I have tried sending Word documents and PDF documents and neither will open when the recipient receives them. When I try to send an email with an attachment to my hotmail account, which doesn't go through simple mail, I receive the following when I try to open the attachment.

Server not found

Firefox can't find the server at 1351311760981%40simplemail.

Check the address for typing errors such as
ww.example.com instead of
www.example.com

Whenever I delete a message via imap, it gets deleted, but simple mail shows error "message(s) not found on server".

Simple Mail 2.80.1 doesn't work under the now public Firefox 7.

Errorcode (German):
Fehler: Simple Mail: [imap.googlemail.com:993,ssl]: Ungültige Antwort: 7 BAD Could not parse command
Quelldatei: chrome://simplemail/content/utils.js
Zeile: 178

What means sth. like:
Error: Simple Mail: [imap.googlemail.com:993,ssl]: Invalid Response: 7 BAD Could not parse command
Source: chrome://simplemail/content/utils.js
Line: 178

Waiting for a fast fix,
as its not doing anything,
and i don't want to switch to an external email tool.

P.S.: I don't know how important it is,

After the release of the new version of Simple Mail I hoped to return back to Firefox (from Opera with its own Emailfunction). But unfortunately I cann receive all my Emails , but connot send any mails . Please fix this bug !!!!!

when i add a background and click apply to all folders it doesn't actually do anything. It would be nice if you could get this to work, because i have a lot of nested folders and do not want to go through them all to get my background.

When i try to enter in my Bookmarks on FastDial's website appear this error:

Because Fast Dial 1.x replaces about:blank pages with its page, when using the Web Developer add-on (which also does this on occasion), you will run into conflicts.

This was finally resolved in Fast Dial Version 2.x.
Fast Dial Version 2.x can be downloaded here

Remember FD v2.x works only in FireFox 3.
Upgrading to FD v2.x is the Recommended solution, although there is a workaround for v1.x available: here
