Pitbull does more than filter spam — it manages high-volume email traffic, IP reputation, queue health and provider behaviour.
High-volume outbound traffic is not piled onto a single IP — it is distributed across controlled pools. Provider-specific delivery policies apply, and new IPs are warmed up safely.
“Pitbull protects IP reputation and improves delivery continuity by distributing high-volume outbound mail across controlled transport pools instead of overloading a single IP.”
Temporary provider blocks are not treated as permanent failures. Mail is not lost — the system waits and retries in a controlled way. Operators can pause, resume and run controlled provider tests.
“During temporary provider blocks, mail is not lost — Pitbull holds delivery in a controlled way, retries and makes the situation visible to operations teams.”
Failed delivery notifications can be kept in logs without bloating the queue. Unnecessary bounce traffic and backscatter risk are reduced. Active or passive mode is selectable from the panel.
“Delivery errors are not lost, but unnecessary bounce emails do not reload the system. Error evidence is preserved in logs.”
The same message is prevented from being queued repeatedly due to temporary errors or retry loops. Resource use and queue load drop in high-volume environments.
“Pitbull reduces resource consumption and keeps the delivery queue healthy by preventing the same email from being queued over and over.”
Live log and analysis data are managed with controlled retention policies. Long cleanup jobs continue in the background even if the panel session ends; critical records are preserved.
“Live log and analysis data are managed with controlled retention policies, keeping system resources balanced over the long term.”
Quarantined messages can be released in bulk. Narrow trusted rules can be created for flows marked as false positives — not a broad whitelist, but proven and limited learning.
“False positives are managed without exhausting operations teams; safe mail is released quickly and similar cases are learned in a controlled way.”
Accept, scan, queue, delivery and error stages are recorded clearly. IT teams can see which provider rejected mail, why, and which policy was applied.
“Pitbull forensic logging shows IT teams the full email journey end to end — problems are solved with evidence, not guesswork.”
Enterprise Capabilities
Phishing, campaign protection and security decision visibility beyond delivery operations.
Continuously monitors provider reputation signals. Automatically slows, pauses or reroutes outbound traffic before reputation damage occurs.
Controls delivery speed when Microsoft, Gmail or Yahoo begin deferring traffic. Prevents queue explosions and improves long-term sender reputation.
Automatically detects suspicious campaigns targeting multiple users from the same external sender. Provides early protection against phishing waves.
Generates proprietary phishing detection signals beyond traditional antivirus and Rspamd analysis. Adds an additional layer of intelligent phishing defense.
Provides administrators with complete visibility into how SPF, DKIM, DMARC, URL reputation, malware scanning, phishing detection, HELO, PTR and Rspamd verdicts influence final delivery decisions.
Displays live delivery health for Microsoft, Gmail, Yahoo and iCloud. Includes queue status, deferred messages, delivery rate, blacklist status and transport health.
Allows administrators to monitor and control ClamAV, Rspamd and internal gateway services. Includes health monitoring, restart, stop, start and automatic recovery.
Pitbull Mail Security
Pitbull Mail Security does more than filter email — it makes delivery flow, security decisions, queue movements and suspicious behaviour visible through clear logs. IT teams can quickly see why a message was delivered, deferred or quarantined.
Email traffic can be monitored in real time. Sender, recipient, subject, status, target provider and security score are visible from the panel.
Makes it easy to see which stage a message is in, whether it was delivered or why it is waiting. IT teams can respond to user requests faster.
Pending messages, retry behaviour and temporary delivery issues can be monitored from the panel. Temporary and permanent errors are clearly distinguished.
Decisions such as quarantine, reject, delivered or deferred are shown with the security signals behind them — helping reduce false positives and improve policies.
When needed, the technical flow of an SMTP session can be examined in more detail — for delivery problems, connection errors, recipient-side rejects or suspicious SMTP behaviour.
Outbound traffic to major platforms such as Microsoft, Gmail, Yahoo and iCloud can be tracked separately. Queues, temporary errors and reputation signals per provider are clearly visible.
Quarantined messages can be reviewed with sender, recipient, subject, reason, security signals and attachment context. Authorized users can release messages securely when appropriate.
Administrator actions are recorded. Setting changes, release operations, security decisions and critical management moves are traceable.
Historical email records can be searched. Review by sender, recipient, domain, status or date makes retrospective incident analysis easier.
Logs are not just raw technical data — summaries, status badges and clear reasons help IT teams analyse incidents faster.
A forensic log is advanced record data for examining the technical trail of an email event in more detail. While a standard log shows whether mail was delivered, deferred or quarantined, a forensic log helps you understand which stages the event passed through, which security signals applied and where delivery issues occurred.
IT teams can answer questions such as “why didn’t the mail send?”, “why was it quarantined?”, “did the recipient reject it?” or “is this a temporary delivery issue?” faster — especially for complex delivery problems and security reviews.
Standard logs show a summary: sender, recipient, subject, status and decision. Forensic logs provide a more detailed technical trail when needed — standard logs for daily operations, forensic logs for deep investigation.
No. Because forensic logs produce more detailed records, they are usually recommended when needed or for a specific investigation period. Standard logging is sufficient for daily use; forensic visibility can be enabled for detailed analysis.
When managed correctly it is not risky, but because it contains more detailed technical information it should be limited to authorized users. Public-facing content should describe the analysis benefit, not internal technical detail.
Delivery delays, recipient-side rejects, suspicious SMTP behaviour, false positive reviews, quarantine analysis and provider-specific delivery problems.
Generally no. It is designed for IT administrators, system administrators and security teams. End users are better served with simpler delivery or quarantine status.
Pitbull Mail Security makes visible not just the outcome of email traffic but the process that led to it — so IT teams can analyse delivery, security and policy decisions faster.
Operational capabilities integrated with Pitbull Secure Gateway platform modules.
The heart of NOC and Operations: view daily traffic, delivery, reject, quarantine and queue statistics in one panel. Track end-to-end message journeys with SMTP trace and message lifecycle.
The Pitbull Secure Gateway outbound relay layer delivers traffic from your server securely via smarthost. Relay IP / customer synchronization and domain-based TLS policies maintain delivery quality.
Prevent sudden throttling and soft bounce waves to Microsoft 365, Google, Yahoo and other major providers. Protect shared IP reputation with per-tenant and domain outbound rate limits.
Security Engine, NOC, Quarantine and all platform modules.
