Post mail?

Question

System administration

Hello.
Tell me where to dig? I have a task to arrange episodic mass mailings from my server. (mailing is legal, we receive a list of clients in our region from the head office). My server is on freebsd 8.3.
Rummaged through a lot of information, but in most cases they tell how to set up a full-fledged mail server with forwarders, mail boxes, etc.
I need much easier.
They send me a list of customer addresses.
I want to take a completed letter and just send it out on behalf of our company. so that the letter comes from our address, for example from [email protected]
I do not need to process replies to this email. for this we have another server.
I just need to send.
Those. unlike most of the manuals, I don't need to create mail system users, give them a password and send a bunch of letters through them.
I need to take the body of the letter and just send it to the recipients.
I ask for help because I'm completely confused in all these exim, sendbox and postfix'ah.

Answer 1

1) make -C /usr/ports/mail/postfix install clean
... disable all options in the configuration dialog.
2) cd /etc && postalias aliases
3) Carefully copy the necessary lines from /var/db/pkg/postfix*/+DISPLAY to /etc/rc.conf and /etc/periodic.conf
4) Add to /usr/local/ etc/postfix/main.cf:
inet_protocols = ipv4
5) /usr/local/etc/rc.d/postfix start
6) mail -s "Vsem Privet" [email protected] [email protected] [email protected] …<letter.txt

Answer 2

Please note that by sending letters to the mailing list, you can automatically get into spam distributors for the same Google or Yandex. For example, if you send letters to non-existent addresses (not necessarily to all, 5-10% of the total list will be enough), if you do not delay between sending letters (you will send 200 letters to addresses * gmail .com within a minute) + There are still some pitfalls.

Answer 3

I will add to 0xE0.
The mail server needs to be raised so that it responds to spam filter requests. This is a very popular defense - to receive a letter, ask the sending server if it is a mail server, and often ask if it has such an address. You will also need to raise the return lines, otherwise more than half of the letters will fly away to nowhere (ie, to spam, it's good if in the user's mailbox, and not immediately on the receiving server).

Answer 4

I sent out up to a million emails a day (broadcast) [it was a long time ago I could mess something up]
1) we used our own mail server, the IP of which must match the registered IP of the domain mail (MX)
2) the outgoing name [email protected] must have a registered robot box :)
3) for mailing, we used the PHPMailer class that connected to our mailer (the mailing script and the mailer were on different servers)
4) when mailing, standard OUTLOOK headers were used
5) mailing went one letter to one address (without copies and blind copies)
6) after sending 100 letters, there was some delay (I don’t remember exactly, it seems to be 1-2 seconds)
7) they sent portions of 100 thousand letters in the queue
8) the letter format is plain / text
could forget some details
yes, the mailing went on for a long time for several hours (it seems more than three), but more than 85% of letters reached subscribers

Here is my script: it-talk.org/topic16134.html If the mailing list is small, for a couple of thousand people, it does a great job.
