Features and bugs:

The file "hosts" how easily to guess, contains addresses necessary you hosts.
Example:
---start cut-----
mail.ru 195.42.2.61
chat.ru 212.24.32.11
---stop cut------

If an address is registered in "hosts" file, "e-rotor" will not try to check his validity! I hope your post server does not change its IP every week :-) But keep it in a mind anyway.

File "temphost" contains fresh internet host address, from a service of DNS. If on that end will answer POP server, and your session will be successful, address will be write in to the list "hosts".

In case of an error and unexpected program closing file "e-rotor2.err" will be created. Please send this bugreport with appropriate comments to me...
