AppSMTP Server Upgrade

As announced, Cornell AppSMTP, a service used to deliver automated email to users from multi-function printers and scanners, applications, and monitoring devices, will require that the email address used is a valid EGA and must be registered with the new AppSMTP system:

https://it.cornell.edu/news/reminder-appsmtp-registration-required-starting-april-19-2021/20210325

Due to limitations of some web applications and hardware devices that cannot be configured to use a valid EGA email address, ITSG will continue to support a local AppSMTP server to relay mail to Cornell AppSMTP system.

On Thurs 04/01/2021 between 6:30 AM – 7:00 AM, the local AppSMTP server, “appsmtp.coecis.cornell.edu” is scheduled to be upgraded with a current system with features that address the requirements in the new Cornell AppSMTP service.

If you notice problems with your applications or devices that generate email, please report to COE/CIS IT HelpDesk <itcoecis-help@cornell.edu>.

CSLinux SSL key changes

New servers were added to the pool of servers for cslinux on 1/28. The new servers had a different SSL key, so you may have received an SSL key warning message in your SSL client about a possible security issue.

We have reverted back to the old SSL key for cslinux to prevent these warning messages. If you have already replaced the SSL key, you may have to switch back to the old SSL key in your SSH client.

Here is the list of valid keys for cslinux to verify on your client:

CIS PhD email alias sending broken due to Two-Factor authentication deployment -7/21/20

Cornell recently turned on two-factor authentication for all student accounts:
https://it.cornell.edu/news/two-step-login-authentication-will-be-added-office-365-login-students-monday/20200716

A side-effect of this is that now external SMTP and IMAP clients (like GMail) no longer work to send from @cs.cornell.edu and @infosci.cornell.edu email aliases

  • Currently there are a few work-arounds:
    • Use Mail client like Outlook, or Apple Mail…others listed at link above.
    • Use Outlook Web Access: http://outlook.cornell.edu
      • When authoring a new message in OWA, click the … at top of message and choose Show From.
      • Then add @cs alias if it isn’t already populated.
        • Click the three dots at top of email and choose Show From Enter your email alias in the now-visible From Field
    • Use Thunderbird (version 77+) to configure IMAP account with following settings:
      • Incoming – IMAP
        • Server: outlook.office365.com
        • Port: 993
        • Username: netid@cornell.edu
        • Security: SSL/TLS
        • Authentication method: OAuth2
      •  Outgoing  – SMTP
        •  smtp.office365.com
        • Port: 587
        • Security: StartTLS
        • Authentication Method: OAuth2
