Guidelines at Princeton
- The largest message that will be handled by OIT's mail servers is 25 megabytes. If a message is received that is larger than 25 megabytes, it will be returned to its sender.
- OIT imposes this restriction to try to prevent very large files from filling up the disks on which mail lives. If the mail disks were to fill, mail would be disabled for nearly everyone at Princeton. The systems will allow 100M through, but this only works if the data is entirely ascii text (i.e. it cannot be unicode).
- If you need to share a file with a large number of people, or if you need to share a very large file, you may want to consider other solutions for collaboration.
Some Considerations When Sending
As a courtesy, people often indicate in the body of the email message that a file is attached. If the recipient does not receive the attachment they can always request another copy. Another consideration when sharing files is making sure that your recipient has the right tools to receive and make use of the file. If you send a very large file to someone who does not have ample free disk space, they may be unable to receive it. If you send a Microsoft Word file to someone who has no application capable of opening the file, they will be unable to view it.
Some Considerations When Receiving
Numerous computer viruses are sent via email attachments. The best defense against receiving an "infected" document or file is using antivirus software on your computer with current virus definitions. You can usually download the latest definitions from your software manufacturer's website or you can contact them directly. Make sure to scan files that are sent to you before opening them. Some antivirus programs can automatically scan files as they are downloaded to your computer.
