Hello fellows,
Let me start another trending topic.

What is the maximum number of ips you have used on a PowerMTA server at the same time ?
 

[Port25-Admin1]

Oh, man, I'm curious about this one.  I've heard some really large numbers from customers.  It is rumored that one customer has 65,000+, but I have yet to actually see it.

[CaLViN]

65k ? Oh!

I am actually using 96x /24 = ~25k ips.
Powermta is not so fast but is still able to handle it. !!

[Port25-Admin2]

What part within PowerMTA "is not so fast"?

[CaLViN]

Reloading takes time.

[Tobias Herkula]

96 /24 Networks? Holy ****, on one PMTA? This must be a motherf***ing monster machine.

I have 7 /24 on 4 PMTAs and thats enough to send Billions of mails per month. What volume are you sending on so many IPs?

[CaLViN]

Well yes, but that is a bit specific project.An i7 box with 32 gb ram works well except the reloading . 
We are talking about many many Billions here. 

[Tobias Herkula]

You are using an i7? What HDD setup do you have, I often ran into IO Problems as soon as the PMTA has to queue some mails. And I already use a RAID10 with 4x SAS 15k HDDs, thinking about SSDs or FusionIO cards...

And is this a Border MTA or some internal stuff, and holy **** what kind of uplink do you have on such a single rick to handly so much traffic?

[CaLViN]

15k drives are good enough but you should try SSD ones.
4x 300gb SSD - Raid 10 is what we are using at the moment.
That box is using 40-50 mbit uplink.

Many many Billions of mail on a T3 uplink? sounds like this is a sms gateway or you are sending really small mails, I easily saturate a 1 gbit uplink with only 4million mails per hour....

Well,4 million emails per hour is using 1gbit fully ? What is the size of a single email body ?

PS: We love FRED.

[Tobias Herkula]

Yeah Fred is awesome, do attend MAAWG Meetings, perhaps the next one in SanFran?

We have a lot of different content, sp mail body size depends on what customers are actually sending, our longterm avg is about 36KB but sometime I see mailstreams with single msg body size up to 500KB (mainly invoices as pdf attachments and such stuff)

so I'm wondering a littlebit about your msg body size, if you really only need a T3 uplink...

@caLVin, @tobias, you guys rock. Thanks Brothers....Stay well and safe.....

Well,
I dont have time to attend those meetings while working on that 25k ips but i will do my best next year.
That project sends small sized emails ranging from 5k to 15k.

[Tobias Herkula]

perhaps the one in vienna, next summer, thats a short trip for us...


ok with msg size of 5kb you could have about 2.5 billion mails per month if you saturate your uplink with 100% all the time, thats pretty good, how many destination domains do you have?


I think our main performance problem at the moment is the sheer amount of different destination domains...
