PREMIUM SPAM INFRASTRUCTURE High-Volume Campaigns • Dedicated IPs • DKIM/SPF/DMARC • Delivery Tracking

INFRASTRUCTURE: Professional spam infrastructure requires more than just SMTP servers. You need proper DNS setup, IP warming, content variation, bounce handling, and delivery optimization. This guide covers building a complete spam operation from scratch.

INFRASTRUCTURE COMPONENTS

Component	Purpose	Recommended	Monthly Cost
Dedicated Server	Host PMTA + email database	Hetzner AX102 (64GB, 8TB)	$45-80
Dedicated IPs	Sending reputation, warm-up	/24 subnet (256 IPs)	$150-300
Domain Pool	SPF/DKIM per domain, rotation	50-200 domains	$5-10/domain
SMTP Software	MTA for bulk sending	PowerMTA (PMTA) v5	$150 license
Tracking System	Open/click/bounce tracking	Custom PHP tracking (included)	Free
Data Cleaner	Remove invalid/bounced emails	Custom Python script	Free
CAPTCHA Solver	Bypass anti-spam CAPTCHAs	2captcha / CapMonster	$0.001/captcha

POWERMTA CONFIGURATION

Code:

Example pmta.config for high-volume sending:

# Virtual MTA per IP
<virtual-mta vmta-1>
  smtp-source-host mail.domain1.com
  smtp-source-ip 1.2.3.4
  domain-key dkim-domain1.key
</virtual-mta>

<virtual-mta vmta-2>
  smtp-source-host mail.domain2.com
  smtp-source-ip 1.2.3.5
  domain-key dkim-domain2.key
</virtual-mta>

# Source groups (cycle through VMTA pool)
<source-group sg-main>
  virtual-mta vmta-1, vmta-2, ... vmta-50
  cycle-strategy round-robin
  cycle-period 100    # rotate every 100 emails
</source-group>

# Throttling
<virtual-mta-pool pool-1>
  virtual-mta vmta-1..vmta-50
  max-connections-per-host 5
  max-messages-per-connection 50
  max-smtp-out 250     # global connection limit
  max-msg-rate 50000   # emails per hour
</virtual-mta-pool>

# Bounce processing
<bounce-queue>
  <rule>
    condition bounce-type 5xx
    action remove
  </rule>
  <rule>
    condition bounce-type 4xx
    action retry 3 times
    if-failed remove
  </rule>
</bounce-queue>

# DKIM signing (automatic per domain)
<auth>
  dkim-sign yes
  dkim-verify no
</auth>

Expected throughput: 50K-200K emails/hour per server

IP WARMING SCHEDULE

Code:

New dedicated IPs need to be warmed up (4-6 weeks):

Week 1: 500 emails/day per IP
  - Send only to engaged recipients (opened in last 30 days)
  - Monitor: open rate > 20%, bounce rate < 3%, spam complaints < 0.1%

Week 2: 2,000 emails/day per IP
  - Add: new recipients (sourced from verified lists)
  - Monitor: reputation score on SenderScore, Postmaster Tools

Week 3: 10,000 emails/day per IP
  - Full throttle: all valid recipients
  - Monitor: IP blacklists (Spamhaus, Barracuda)
  - Check: deliverability to Gmail/Yahoo/Outlook specifically

Week 4: 30,000 emails/day per IP
  - If reputation is clean → full speed
  - If any blacklisting → drop back to Week 2 levels

Week 5-6: Ramp to maximum
  - Up to 100K/day per IP for established domains
  - Continue monitoring: any drop below 95% inbox rate → reduce

IP pool strategy:
  - Use 10-50 IPs in rotation
  - New IPs: add 5 per week
  - Bad IPs (blacklisted): immediately remove from pool
  - Keep 20% spare IPs for emergency rotation
