I’m not really confident in this answer but, “not that I’m aware of”.

I use mxroute as a paid / hosted IMAP & SMTP server. They run spam assassin, but it’s obviously not trained on my own reports.

I’ve grown fond of Thunderbird as an email client. It’s spam management is clunky but if you spend 15 minutes or so learning how it works, and then train it with both junk and not junk, it works reasonably well.

Sadly, it does occasionally throw a false positive, like maybe twice in the last year it identified a legit email as spam.

So, while I’m running a spam assassin and thunderbird combo, it’s really TB that’s doing the work because SA is really just filtering the super low hanging fruit.

TB is doing a very respectable job, but needs to be trained.
