Поскольку в hotmail’е разумной жизни нет, а спам оттуда прёт уже десятками одинаковых писем в день, приходится защищаться со своей стороны.

Ежели кто не хочет (или не может) отвергать всю почту оттуда, в sendmail’е это можно сделать для одного конкретного получателя примерно так:

SLocal_check_rcpt
R$*                            $: $>canonify $1
Rdil < @ domain . tld . >       $: @HOTMAIL $&f
R@HOTMAIL $* @hotmail.com $*   $#error $@ 5.7.1 $: "550 fuck off"

Естественно, при желании можно проверять получателей по внешнему списку.

Мне также интересно было бы узнать, как это делается в других распространенных почтовых серверах (exim, postfix, MS Exchange). Если кто знает, поделитесь.

Вот этого дерьма на меня за ночь высыпалось штук тридцать:


Subject: Your email was blocked
From: MSN Hotmail <help@hotmail.com>

Thank you for sending an e-mail message to help@hotmail.com. However, this is not a monitored e-mail address.

Sign in to your Hotmail account and click "Help" for the most up-to-date information on this issue as well as recent customer questions. If you need more assistance, you can contact us through Help, and we'll respond within one business day.

Having problems signing in? If you need to retrieve or reset your password, add or update your alternate e-mail address, or change your secret question, go to:

Click "Help" for the most up-to-date information on each of these tasks.

NOTE: You will need to provide the same answers to the account profile questions as you entered when you signed up for your Hotmail account. You will also need to provide the same answer to your secret question that you created during the sign-up process.


Note: We recommend you change your Secret Question and Answer when you update your password. This improves the security on your account. Your secret question allows only you to retrieve your password online if you ever forget it. If you are using a non-English version of Hotmail, your password, like your sign-in name, must be typed in Standard English-based text.

Warning: To help protect your personal information, a Hotmail employee will never ask you for your current password, either by phone or e-mail. Hotmail requires your password only when you sign in to your account and even then, your password is not displayed on screen. If you receive a message that asks for your current password, please forward it to abuse@hotmail.com immediately and do not respond to the message. Never share your password or secret question and answer with anyone else. And change your password and secret question regularly to increase the security of your account.
