IIRC, there wasn't really anything we could do with yahoo.... I think they were the one that told us that their postmaster account just goes to /dev/null.
But, they mainly throttled, so it just meant things may or may not get through instantly. We do try to educate our users that e-mail is not IM....it also isn't deterministic. Though it is annoying when you get a flood of notifications...and can't tell among the down notifications coming after the up notifications, what stuff is still down. And, after some LISA I went to....we changed notification-interval on most things to 1 day, so it can take a while before nagios reminds us that something is still down. Though I'm pretty much the only person that isn't ignoring nagios notifications now. I have often thought about turning it off, and seeing how long before anybody notices. Except we share our nagios server with the windows group....and they notice. And, my project to upgrade or replace nagios keeps getting pushed...so I haven't been able to do that yet. I did spot the other day, that one of the admins that frequently openly admits that he ignores notifications (even for stuff he's responsible for, which makes it so annoying when I ask if he's doing anything about X being down....also odd that one of the SLA groups he takes care, is located across the street from my home...but I don't have access there (and a federal building)....I'll be home when I get the notification...but get to work and find out that he has no idea that there's a problem....until they call him. Not like they could e-mail him... that their server (which does everything, including mail) is down.... With AOL there was a feedback program, where we could see what emails users that seemed to come from us that they reported as spam.... The hardest part was that we allow users to forward their email anywhere...spam and all. But, many of the big providers couldn't understand that we weren't originating that spam. It was against policy for us to remove anything that was marked as spam (but if they were an active student or employee, their email would go through our spamassassin system [unless they opted out] so it would have scoring....) But, we still had to forward all of it, no matter how ridiculously high the spam score was. But now with MeritMail...they have an ironport system that filters out a large amount of the incoming spam, so users never see it (whether they forward away or not) (and we don't have the quarantine or user whitelisting, etc. capabilities) I don't think we were asked if that was okay....though they are also currently not charging us for the ironport add-on to our system. OTOH, we scraped our spamassassin system....so people that have other email addresses (i.e. colleges that used to run their own email system, but switched to us but still need old published addresses to work) that now alias back to their main account, get a ton of spam. Since we can't put 100+ extra domains into a zimbra system and not enable all the users to those....I have a (pair of) special MX to do the envelope rewrite to get it into Zimbra (which bypasses the ironport reputation by IP that cuts down on most of the spam...). Hmm, I see one of my smtp servers is on a block list now.... Our spamassassin ran at the MDA level, which is basically what was outsourced. Since users all had controls for their spamassassin settings (though most of them didn't know that). At one time, a former admin played around with spamassassin on the MX and reject stuff higher than 14? But, that caused lots of problems. Though we do use RBLs, and I did add it SANE-SECURITY to our clamav. Wonder if I can sneak in spam filtering now.... Merit is supposed to be going to having ironport for our outgoing emails soon....hopefully that'll help with the students that respond to spearphishing. I wonder if we're number 1 yet, or have exceeded 1000 user's compromised in a year. Only one person (that I know of) has had consequences for responding to spearphishing.... they took her email account away from her. But, not before doing there was a 7th time.... We did have some fun when Yahoo was blocking us....having to ask Yahoo to ask Yahoo to stop blocking themself. Guess where we had outsourced our email to before Merit....
