I wrote a daemon that monitors a mailbox that users can submit spam to, for spam that makes it through the other filtering layers. The daemon finds the original message in the user's mail directory, reads the headers, tracks down the originating network using whois, and then blackholes the network and emails me a notification about it.
Some networks are whitelisted for practical purposes. Google's one of them.
If necessary, I could provide a list of the subject lines of the emails that have been reported. A YC company, Zenefits, is one offender that comes immediately to mind.
While we're waiting for Monday, here are some subjects of spam emails I've received from Gmail's SMTP servers recently. Mentions of my domains replaced by example.com:
Example.com SEO Issues
Tough Times With Example.com? Needs Attention!!?

Back. Here's a recent selection of subject lines, extracted from spam daemon replies. The "Zenefits + Problem" ones are funny .. my dba is "No Problem", and they're not smart enough to correctly handle that I guess, which makes sense, since they're also dumb enough to spam me. I've never replied to any of their messages.
"Re: Zenefits + Problem"
"Higher Targeted Traffic: Associatedtechs.Com"
"Re:re: UL,CE,ETL Split-core Current Transformer(0.333V or 1A/5A output) ,Rogowski coil,hall AC-DC transducer"
"Poor support processes could be costing you customers"
"Get ranked higher:"
"Higher Targeted Traffic: Associatedtechs.Com"
"Re: Zenefits + Problem"
"Re: Zenefits + Problem"
"Your Website...!"
"Get ranked higher: associatedtechs.com"
"Google Update for: associatedtechs.com"
"How to increase your website traffic and generating leads??"
"Zenefits + Problem"
"Mobile Apps Development"
"Digital marketing proposal- www.associatedtechs.com"
This isn't a complete list, sadly, since it turns out the daemon isn't logging ban attempts against whitelisted networks. I should fix it so that it does.

But not until Monday. I'm going camping.
