Is this the case for O365 hosted email as well, or just a Hotmail thing?
Speaking as someone being dragged kicking and screaming from on-prem
Exchange to a subdomain of our beloved corporate overlords' O365 tenant,
this is the sort of thing I have nightmares about.

Yeah, I always understood that to be the transaction: I exchange
permission to send me an initial marketing mail in exchange for a 0.17%
chance of winning a widget. Once I get that message, from there I can opt
out or not depending on how useful I perceive the content to be.

[mailop] VERP generating syntactically invalid return-path?

2016-02-02 Thread Dave Pooser 
A contractor just started getting bounce messages when he tries to email
$DAYJOB -- the message is accepted by our Exim frontend but then rejected
by our Exchange 2013 server with the error message below (example.com and
example.net are placeholders for two different .com domains; outside
sender is usern...@example.net and my recipient is u...@example.com):

Failed to deliver to 'u...@example.com'
SMTP module(domain mail1.example.com:25) reports:
return-path address
