Why does Gmail not filter messages from invalid senders?

It seems you received spam.
There is probably a link in that email that they want you to click on.

the Since The address of unwanted emails is usually random, often false (but sometimes it seems legitimate), so your answer bounces.

Do not click on the link. Don't answer either. Just delete the email.

Whenever you receive unsolicited emails, not even open that. Again, erase it.

Another possibility of rejecting answers is that a company that has your email address (maybe you did business with them in the past) is sending you an email with a Do not answer from the address, which is intentionally set to bounce, because they don't (want) to monitor that mailbox.
This does not seem to be the case in your example. Usually, these types of emails are offers for something, but what you describe (a reference to a non-existent order) is a typical malware spam.

postfix – check_client_access for all local senders?

I'm using Postfix 3.1.0 on Ubuntu 16.04 and I'm trying to get Amavis to filter my outgoing mail from users authenticated by sasl and from mail forwarded from the server through procmail, using a policy bank like this:

$ interface_policy {& # 39; 10024 & # 39;} = & # 39; INTERNAL & # 39 ;;
$ policy_bank {& # 39; INTERNAL & # 39;} = {# mail originated from clients in cidr: / etc / postfix / internal_clients_filter
bypass_spam_checks_maps => [0], # spam-check outgoing mail
bypass_banned_checks_maps => [0], # prohibited check outgoing mail
bypass_header_checks_maps => [0], # header-check outgoing mail
forward_method => & # 39; smtp:[]: 10025 & # 39; # # Postfix listener on port 10025

In my main.cf I have:

smtpd_sender_restrictions =
check_client_access cidr: / etc / postfix / internal_clients_filter,

And in my master.cf, I have: inet n - n - - smtpd
-o smtpd_recipient_restrictions = permit_mynetworks, reject
-o smtpd_restriction_classes =
-o smtpd_delay_reject = no
-o smtpd_client_restrictions =
-o smtpd_helo_restrictions =
-o smtpd_sender_restrictions =
-o mynetworks = / 8
-o smtpd_data_restrictions
-o smtpd_end_of_data_restrictions =
-o local_header_rewrite_clients =
-o smtpd_error_sleep_time = 0
-o smtpd_soft_error_limit = 1001
-o smtpd_hard_error_limit = 1000
-o smtpd_client_connection_count_limit = 0
-o smtpd_client_connection_rate_limit = 0
-o smtpd_milters =
-o local_recipient_maps =
-o relay_recipient_maps =
-o receive_override_options = no_header_body_checks, no_unknown_recipient_checks, no_address_mappings

My question is, what should I put in the internal_clients_filter file?

If I try the following, it seems to be ignored as far as I can see: SMTP FILTER:[]: 10024 SMTP FILTER:[]: 10024

And, in fact, when I search for mail.log, the IP of authenticated users with sasl is given as a client machine in any case, which could be anything:

June 15 17:57:20 server postfix / submit / smtpd[25939]: B5BB220D60: client = mail-yb1-f178.google.com[], sasl_method = PLAIN, sasl_username = username

Or am I barking the wrong tree?

How do I send library alerts to random senders?

I do not control access to the library, so the sender might be someone I do not know and, therefore, would not be on my list of alerts. Is there a way for the list to respond to senders without explicitly entering each one?

List of automatic senders for DDL sites (send with one click) | NewProxyLists

Did not JMZ have a DDL sender that saved the preferences (auto warezlinkers)? I remember that linkplz ddl also had a sender that saved the preferences but closed. Most people never used to save preferences.

Anyway, the whole way of how people submit is terrible. All you need is the email address that the website uses to send and you can send it for them.

A few years ago, when DDL sites used to get much more traffic, people would set up a DDL site and advertise it on WJ. All that could be done in less than an hour. People with 5-star warez sites in large DDLs would be sent to this new fake site and would use the same email address they use to send to all DDL sites, since it is the simplest and most unique option if you use a sender of DDL.

What the person who created a new DDL could do is register as a regular member on the 5-star website, post their own topics and links and then use the email address that the 5-star site used to send to their site of DDL. the 5 star site to the largest DDL sites. Your publications would get a lot of downloads and they would make a lot of money. His own personal DDL site was only to gather email addresses so as not to generate traffic or downloads.

You can still do this, but since DDL sites do not get that much traffic, it's not that common. However, it happened a lot when I worked at MechoDDL since Mecho was one of the largest DDL sites after Katz closed. To try and avoid it, I used to keep track of the IP address they would send, so let's say that the real owner used phazeddl to send it, then mark it to check if the topics sent came from another DDL sender or a different IP than the one It was generally used. used. I created a lot more work, but it was the only way, since I could not introduce a password system, since in any case they would only use the same password in all the DDL senders to facilitate the sending. I tried a more secure API system to send, but it did not really work since people already had their own systems.

What got even crazier was that the smart guys were able to trace from their own fake DDL sites what the DDL senders that the administrators of the 5-star warez forums were using and then use those that make it impossible to track shipments not official

This is one of the reasons why warez 5-star sites often sent crap messages or issues that did not have the necessary number of file hosts with Gold Rating and were allowed to maintain their rank since it was not really his fault.

Who would have thought that their world was an underground world for DDL senders?

Directory of senders | Fresh store builders forum

I have a directory sender that I bought a long time ago that I am investigating if I could share it and if so, I will send it to you. It has around 3000 directories, not all work, but many. Meanwhile, I found some users of free directories.


This allows you to send to more than 350 free directories. 350 is a lot and I do not think I need more, but I could also add directories manually to the list that I create.

Here are some more links I found on the web. I have not tried them yet, but if someone knows more about them or has any chance, please share your opinion.


Good luck =)
