Yes it is amazon and i can restrict or remove the restriction on port 25, i asked this question as i saw requests coming in from unknown hosts that i know are not aware of my domain (since mine is very new). That's when i was thinking why not block 25 and asked this question :)

Who is your host? IF its amazon they have to unblock port 25 for sending if you have more than one IP address. You might want to make sure they >don't have any restrictions on you. And...if they do they should have procedures for getting them lifted.

Hi

I am newbie into mail and mTA setup.

I have my port 465 smtps/587 (submission) working, so do i need to keep port 25 open? I am asking this because when i try to telnet gmail then it does not work, so was wondering if blocking port 25 will stop all my incoming mails or >>not?

To try it out i did telnet gmail like below
telnet gmail-smtp-in.l.google.com 25
it just said trying and did not work

Then i sent a mail from gmail to my mail ID after blocking port 25 and I did not receive the mail, dont know where it went :(

Will be good to know about my questions from experts.

Regards
Jithesh
