Dear hikyaku users,
Due to an explosion of spam mails circulating on internet, fighting against spam calamity has become our first priority.
We are now testing the following 2 types of filters.
1) ip based filter
We count the number of e-mails sent by each server (we take into account the server's ip address and not host name because the latter may be easily falsified) and when this number has reached a certain threshold, they are flagged and hence after all the e-mail originated from these servers will be refused with the mention "you are in a blacklist".
2) header based filer
We analyse the header of each e-mail received before delivering to the users and when they contain spam related terms such as "online pharmacy" or "mortgage rate", they will be discarded.
Though, our filters are still primitive, hopefully they should decrease the number of spams that hikyaku users receive (we are now working on a more sophisticated mail filter).
If a hikyaku user encounters problems of mail delivering, please contact us by mentioning your host name (ip address if possible) and mail headers.
Thank you very much for using hikyaku mailer
