Comments on: My Experience with Anti-Spam Mail Measures http://www.jdr-japan.com/blog/2008/04/30/my-experience-with-anti-spam-mail-measures/ Our blog about the Japanese market and consumers today Wed, 19 Nov 2008 23:34:07 +0000 http://wordpress.org/?v=2.5.1 By: Ken http://www.jdr-japan.com/blog/2008/04/30/my-experience-with-anti-spam-mail-measures/#comment-226 Ken Mon, 19 May 2008 14:40:01 +0000 http://www.jdr-japan.com/blog/2008/04/30/my-experience-with-anti-spam-mail-measures/#comment-226 Definitely what is most frustrating is when the ISP doesn't tell anyone that they've blocked port 25. Now we just add that to the list of what might be wrong! What I've seen that's even worse is limiting people to sending only 10 emails in 10 seconds - without telling them! This can be a disaster if you're running an email marketing list. Definitely what is most frustrating is when the ISP doesn’t tell anyone that they’ve blocked port 25.

JEAG recommends to use Port 587 because it is defined by RFC2476. I am not sure how many ISPs use Port 26… JEAG recommends to use Port 587 because it is defined by RFC2476.

I believe customers should pressure on the ISPs to take account of usability as well as to offer better solutions. Yes, I also realize that ISPs outside Japan start blocking port 25.

It is not just in Japan, i have talked to ISP's all around the world and this is a method some of them are applying. Unfortunately, this method increases the false positive as well, but i guess that as long as the customers won't put pressure on the ISP, it will consider for them a good solution.
