"Works great to notify of new emails in background"
The latest 3.x version works fine (previews reviews 'Cons' have all been addressed... if properly installed and configured).
Runs in the background and provides colorful count (number) of new emails on the single X-Notifier envelope icon. Also has an -optional- 'toolbar' that can show individual accounts... (off by default).
Comes with major email provider scripts embedded in program... also allows for many custom scripts downloadable from support site for various other email providers. And has built-in scripts to support POP3 or IMAP access.
Can customize default check interval or per-each-account checking interval. Can customize sound alerts, and choose either inbox-only or include other folders of webmail accounts.
Supports other email features, like multiple accounts with a provider, etc.
Available several browsers (except Internet Explorer)... Mozilla version for Firefox, Sea Monkey, Thunderbird... other versions for Chrome, Opera, Safari 6.
Not all optional features are available from Options menu... some features require edit of configuration file (Mozilla version... Firefox, Sea Monkey, Thunderbird).
A very customizable email checker that runs in the background when you have browser open... and notifies user of new email count for multiple emails. Has optional toolbar and allows for creation of custom scripts to access non-webmail email providers, as well as those accessible by POP3 and IMAP... and other account providers such as Twitter, Facebook, deviantART, LinkedIn, etc.
If you have trouble setting it up, support forum is a great place to get troubleshooting help.
