SMTP proxy list.
Checks and status
of every address.

The proxy list page starts with the module’s tabs and a choice of node and period. By default the list shows the whole fleet, but you can narrow it to one sending server — then only its addresses stay in the table. The period — 24 hours, 7 or 30 days — only affects messages and the delivered share. The strip below tells you which columns come from the Hub’s checks and which from MTA reports; on the right — a CSV export of the selected addresses and a link to import. Grade, blacklists and DNS are the address’s current state, so they don’t change when you switch the period, while messages and the delivered share are recalculated.

• Module tabs — Overview, Proxies, Pools, Rules, Gates, Checks, Analytics, Own proxies, Sources and Log; this page is the “Proxies” tab.
• Node choice — the whole fleet or one sending server; the table and metrics are recalculated for the selected node.
• Period — 24 hours, 7 or 30 days; changes the message count and the delivered share.
• Source hint — grade, blacklists and subdomain records come from the Hub’s checks; messages and delivery come from MTA accounting.
• Export CSV — downloads the current selection, without passwords.
• Import — takes you to adding addresses as a list.

Grade, blacklists and DNS are the address’s current state: they don’t change when you switch the period.

Eight metrics give the overall picture of your proxy fleet: delivery, fit for mail, blacklists, reverse DNS, own VDS, free addresses, time to banner and the last check. The color of the stripe on the left tells you whether all is well: green is normal, red means there’s something to look into. Under each number, small print says how it’s counted. Many metrics work as buttons and immediately select the matching addresses in the table, while “Delivered by fleet” and “Last check” lead to “Analytics” and “Checks”. In the example, 26,822 messages went out over the week with a 95.1% delivered share, seven addresses of eight are fit for mail, and reverse DNS doesn’t match on three.

• Delivered by fleet — the share of delivered messages across all proxies over the period, and the total number of messages.
• Fit for mail — how many addresses have port 25 open and a grade from A to C.
• On blacklists — how many addresses got listed — major and minor lists shown separately.
• Without a reverse record — how many checked addresses have a reverse DNS record that doesn’t match the forward one.
• Own VDS and Free — how many live addresses come from your own servers and from public lists.
• To banner — how fast, on average, the recipient’s mail server answers through the proxy.
• Last check — when the Hub last checked the addresses and how many are waiting in the queue.

The numbers in the screenshot come from a sample fleet. “3 / 8” for reverse DNS means that for three of eight checked addresses the records don’t match.

Under the metrics are the search bar and the proxy list filters. You can search by entry or exit address, proxy name or subdomain; the search runs when you press Enter. The state buttons show right away how many addresses are in each, and the filters below refine the selection by server, pool, source, grade, country and blacklists. The check button on the right takes all the addresses found, not just the visible page — so a proxy check runs on exactly the group you need. In the example the chips show reserve 2, sending 5, quarantine 1 and dropped 1 — all nine addresses together, and “Progress” next to the button shows how checks already started are going.

• Search — by address, name or subdomain; runs on Enter.
• States — All, In testing, Accepted, Reserve, Sending, Quarantine, Dropped — each button has its own count.
• Filters — node, pool, source, grade, country and the “Blacklists” tick box.
• Check N — starts a check of the whole selection, even if the rows span several pages.
• Progress — shows how a running check is going.
• How to read these numbers — opens the states help.

The number on the “Check” button changes with the selection conditions.

The help opens right under the filters and explains each proxy state together with the number of addresses in it. An address always has one state, so all the states add up to the number of addresses in the list. It also says how an address gets into quarantine and what happens to dropped ones: free ones are deleted, while bought ones and your own VDS stay. It explains separately why “Fit for mail” isn’t a state. When you no longer need the help, you can collapse it. For example, a free address with a closed port doesn’t linger in quarantine — the check removes it right away, and the Hub remembers its fingerprint so that collection doesn’t add the address again.

Enlarge

• In testing — the address was added from a source or by import; there’s no check result yet.
• Accepted — passed the check but isn’t in any pool, so it doesn’t send.
• Reserve — sits in a pool and waits to replace an address that fails.
• Sending — sends mail: the subdomain is issued, DNS is visible, the node knows about it.
• Quarantine — pulled from sending for a while: a pool rule fired, port 25 closed, or the rent ran out.
• Dropped — failed the check or was retired manually; bought ones and your own VDS stay in the list, free ones are deleted.

A free address is deleted together with its fingerprint so that collection from public lists doesn’t add it again.

The main part of the page is the proxy table. One row shows everything about an address: entry and exit, seller, country, sending server, grade, blacklists, subdomain records, messages over the period, delivered share and state. At the top are the sending addresses by number of messages, below them reserve, quarantine and dropped, and an address with poor delivery is marked by a red bar. You can sort by any column, and the summary under the table matches the “Overview”. In the example px-04 sent 5,151 messages with a 96.9% share, px-05, which is on blacklists, delivers 78.9%, and px-06, in quarantine with grade D, managed to send 4,560 messages before it was pulled.

• Proxy · entry → exit — the name, the connection address with its port, and the exit IP the recipient sees.
• Source and country — who the proxy was bought from and which country the exit address is in.
• Node — the sending server the address is tied to through a pool.
• Grade — the address’s rating from the checks, A to D.
• Lists and DNS — whether the address is on blacklists and whether the subdomain record is visible.
• Messages and delivered — how many messages went out over the period and what share arrived.
• Checked and state — the time of the last check and the address’s current state.
• Totals under the table — how many addresses are in each state and grade; matches the “Overview” tab.

The state is now, messages are for the period. An address in quarantine can show messages if it sent them before it was pulled.

Tick rows and an action panel appears above the table: check, put into sending, move to a pool, to reserve, retire or delete. It says how many addresses are selected and applies one action to all of them at once — no need to open each proxy separately. Before deleting, the Hub asks for confirmation and tells you how many of the ticked ones are sending mail right now and how many are paid for. At the bottom the panel reminds you that the gate and DNS are updated as a separate step. This is handy when you need to put several checked addresses into sending at once, or take a whole group found by a filter out of service.

Enlarge

• Check — starts a check of the ticked addresses.
• Put into sending — moves the addresses into service.
• To pool — adds the ticked addresses to the chosen pool.
• To reserve and Retire — take addresses out of service: into reserve or for good.
• Delete — removes addresses from the list; before that the Hub shows how many of them are sending and how many are paid for.
• Clear selection — removes all the ticks.

The panel only changes the list in the Hub. The gate table and DNS records are updated as a separate step.

You can switch the table to cards — the same proxy list, just more compact. Each card is one address with the essentials: the color of the top edge shows the state, the bar shows the delivered share, on the right are the messages for the period, and a red tag marks blacklists. This makes it easy to scan the whole fleet and spot a problem address right away. Clicking a card opens the address’s page, and the selection and order of addresses stay the same when you switch. Cards are better for a quick look, the table for comparing columns across addresses and sorting them by any metric.

Enlarge

• Top edge color — the address’s state: green — sending, blue — reserve, red — quarantine, gray — dropped.
• Bar — the share of delivered messages over the period.
• Grade and message count — the address’s rating and how many messages it sent.
• “Listed” tag — the address is on blacklists.
• Card — click it to open the address’s page.

The table is better for comparing columns, cards for a quick look over the addresses.

Click the “On blacklists” metric, and only the addresses it counted stay in the table. In the example these are px-05 and px-06. The caption above the table names the selection — “Blacklists · in the fleet”, the “Blacklists” tick box in the filters switches on by itself, and the check button now shows 2. The metrics count the fleet without dropped addresses, which is why the caption spells out the scope — “in the fleet”. So in one click you get from an overall figure to specific proxies and can recheck them right away. The same trick works with other metrics too — for example, “Fit for mail”, “Without a reverse record”, “Own VDS” and “Free”.

Enlarge

• Table caption — names the condition and the scope: “2 addresses of 9 · selection: Blacklists · in the fleet”.
• Tick box in the filters — shows which condition the metric switched on.
• Check 2 — the check takes only the addresses found.
• Reset filters — brings back the full list.

The metrics count the fleet without dropped addresses, while the states count the whole list, so their scope can differ.

If no address matches the conditions, instead of an empty table the Hub explains what happened. In the example someone looked for grade A proxies in Lithuania — there are none in the fleet. The Hub says how many proxies there are in total and that none match these conditions, and right away offers the closest result: without the “Country” condition two addresses would be found, and the “Show them” button opens them. “Reset everything” brings back the whole list. This way a selection that’s too narrow doesn’t lead to a dead end: you see at once which condition is in the way. There’s nothing to go through by hand: one button takes you back to the closest matching addresses.

Enlarge

• Filter caption — which conditions are selected now; in the example — “Grade A · Lithuania”.
• Closest match — which condition to remove and how many addresses you’d then find: without “Country” — 2 addresses.
• Show them — opens the suggested selection.
• Reset everything — clears all conditions and brings back the full list.

Instead of an empty screen — the reason and the next step.
