SimpleCheck doesn't require installation so you can simply copy it and execute. All SimpleCheck settings are stored in a file with scpf extension (SimpleCheck profile).That makes even easier to move things around.

How does SimpleCheck work?
Each individual mailbox that is stored in SimpleCheck can have time interval or particular time of a day when new messages should be checked. When program detects new messages in any of mailboxes it notifies you by next possible means:

1. by a selected (. wav) sound or/and
2. by flashing system tray icon or
3. by an always-on-top message box or
4. by starting e-mail client or
5. by popping up its own result window

SimpleCheck has a lot of customizable settings. For each account you can choose sound notification, message filters, check schedule, notification sound and an e-mail client. There are also some global settings that allow you to change SimpleCheck behavior when there is no dial-up connection, setup proxy SOCKS server and specify default behavior for working with messages.

The new messages can be viewed in a result window that consists of two parts:

• accounts tree
• message headers

Filtering is essential part of SimpleCheck functionality. Message filtering rules can be specified for each account or for all accounts. Messages matched by filters can be automatically deleted, loaded in a preview window, saved to a disk, or an error message can be sent back to the sender. Global filter can be loaded from a file and shared between several users in a local network.

SimpleCheck can also launch your favorite e-mail program, delete unwanted messages and download one or more messages into a message preview window, as well as it can be used to compose and send a quick reply.

User can have any number of SimpleCheck profiles (.scpf) with different mailboxes, or with the same mailboxes but different settings. The profile can be easily open from the program or specified as a command line parameter.

SimpleCheck supports secured POP3 and SMTP authorization: APOP command for POP3 servers and AUTH CRAM-MD5 for SMTP.

SimpleCheck also has auto dial/hang-up features.

Malware Analysis:

Tested for malware on 2009-02-06; no malware found.
Note: the file was submitted to Virustotal, a service that analyes files. Virustotal tested the file with 39 different antimalware programs; 38 of the 39 judged the file safe. eSafe labelled the file as a "Suspicious File". This may simply be due to the fact that the software establishes network connections to check email.

I also submitted the file to Jotti's Online Malware Scan, which scanned it with 20 antivirus programs, all of which judged it to be OK.

I've used SimpleCheck for several years on several systems and judge it completely safe to use.
