Q: Why am I getting a Bobo with your canned meat email error message?
Unable to send email through outgoing.mit.edu
Trying to send authenticated email through outgoing.mit.edu generates the error "554 5.7.1 Bobo with your canned meat?" Note: also check the list of mail errors here: Email bounce error messages
The mail is rejected by outgoing.mit.edu
MIT still operates an authenticated SMTP server on campus for IMAP users and other members of the MIT community needing to send email via SMTP
There are some limits in place on this server to prevent intentional or unintentional use of it as a bulk mailing or spam server
A rate limit has been placed on outgoing.mit.edu limiting each user to under approximately 1000 recipients per 24 hours. This rate limit is enforced by outgoing.mit.edu.
The count is by individual recipient in the header - a single mailing list counts as one recipient regardless of the number of recipients on the list.
If you have a legitimate reason to be sending bulk email, contact email@example.com and we can work with the network team to adjust the whitelist.
If you do not think you are sending enough email to trigger this limit, also contact firstname.lastname@example.org and we will try to figure out what is causing the block to be triggered. There may be a spammer using your account, or you may have a mail client sending duplicate messages over and over, or some other trouble that should be stopped.
