Who is affected:
All bulk-mail users (senders)
The old smtp.humboldt.edu server will be retired as part of our Zimbra to Google migration.
Affected in what way:
The DNS record for ITS' remaining bulk mail server (smtp.humboldt.edu) will be redirected to ITS's new bulk mail server. (Users should not experience any problems, as TCP 25 firewall exceptions have been migrated.)
