had a couple spam issues lately.
first a wordpress site i was hosting was successfully attacked through a buggy plugin. so the site was rolled back to before the problem started.
then a couple weeks later an account was compromised, sending out a deluge of spam. this was caught and the password changed almost immediately.
senderbase registered the drop in volume by the next morning. and by the next day it was back to 0.0, where it has stayed ever since.
but sender score is another story completely:

they also have a list of sending domains that includes 16 domains atm. some of them i recognize, but most i dont.
whats more, im still getting complaints from my subscribers that their outbound mail is landing in spam folders. however im not on any blacklists and havent been for nearly a week.
