[FreeBSD-Announce] FreeBSD.org outgoing mail system changes

Due to circumstances beyond our control, we need to change the outgoing SMTP 
server address for FreeBSD.org email.  We are aware that there are going to be 
challenges due to SMTP sender reputation systems.

At present, email is sent from:
mx2.freebsd.org 2001:1900:2254:206a::19:2

It will be changing to:
mx2.freebsd.org 2610:1c1:1:606c::19:2

These addresses have been listed in our SPF records for some time.  We have 
planned to make this change for a while but external circumstances have forced 
accelleration of the change.  We must begin rolling out these changes over the 
next ~24 hours.

We anticipate that there will be a period of time of frequent false-positive 
spam detection with hosted mail providers.  If you find that your FreeBSD email 
has gone missing on a hosted mail service, it would be prudent to check your 
spam folders.  This is likely to require some training to stabilize.

We apologize for the inconvenience.
