Organization of mass mailing - Linux + Exim/Postfix + Web interface

Question

linux

Available:
- dedicated server
- 5 ip-addresses
- 1 domain

Need to organize a mass mailing with a web interface (considering purchases or writing).
The idea is such that I don't want to get into the blacklist, I want to send out things in turn by 5 ip.

Answer 1

1) To be honest, I have not found any open-source mailing list managers who are sane.
Of the interesting paid ones, there is InterSpire Email Marketing Software (http://www.interspire.com/emailmarketer/) or ActiveCampaign Email Marketing (http://www.activecampaign.com/onsite/). Personally, I like the second one better.
2) Sequencing is a bad idea, because IP gains reputation from time to time. The higher the reputation, the more incoming emails/sec the remote server will receive. If you send spam (or bought/stolen/etc lists - then you will end up in spam sooner or later - usually right away).
3) For mass mailings, all your IPs must have a reverse DNS record (PTR Record, Backresolve)
4) All your IPs must be registered through a Feedback Loop with bulk email providers. mail
5) You must use SPF/SenderID records for your domain and not change your domain
6) You must always read your address [email protected]_domain.ru
7) You must use DKIM/Domainkeys digital signatures for all your outgoing emails
8)… and preferably DMARC to monitor all this
9) You should provide the user with the ability to unsubscribe from your mailing lists in 1 click (as a rule, List-Unsubscribe is used: a header with mailto:// or http:// - https:// links). I clicked on the link and I responded without question.
10) You must have a transparent and accessible Privacy Policy
11) For mass mailings, you should not use anonymizers in Whois for your domain. those. anyone who makes whois your_domain.ru should see the current address, owner's name, phone number and email of the domain owner. If this is not the case, your reputation will not be very good and you will fall into spam
... well, that's right - a short list. PS: I can help set up the system

Answer 2

phplist for web interface
ip rotating on iptables
dkim spf ptr for all ips and domains.

Answer 3

Even with 5 IPs, you can get blacklisted very quickly.
I advise you to use AMAZON SES. Even with large volumes, the cost is negligible, compared to similar services (mailchimp) about 100 times less. I use it in a small project .
