BTW, blocking outgoing tcp 25 is common, but I've never heard of an ISP
blocking 587.  What would be the point?

Well, theoretically speaking...

Many ISPs charge extra for extra email addresses.  They might block 587 to
force people to buy this service from them, instead of getting it elsewhere. 
A lot of the business these days seems to be about creating a captive audience.
