Message Size Limitations

The maximum message size which will be accepted by MBARI's shore-based mail servers is 25MB. If you attempt to send an email message larger than this, you will receive an automated response telling you that the message wasn't delivered. Additionally, messages sent to the R/V Western Flyer (destination addresses of the form wf## or name-wf) are limited to 256KB.

If you need to deliver larger files to MBARI, use one of the following alternative data transfer methods:

  1. Use File Transfer Protocol (FTP) to transfer the file or files. MBARI provides an anonymous FTP site where you can upload files for MBARI staff members. Instructions on using the FTP site for file transfer may be found here.

  2. Compress your attachments to get them below the size limit. Brief instructions on how to compress files using some popular utilities are linked below.

  3. If your attachments cannot compress to a small enough size and you cannot use FTP for some reason, then we suggest that you use an independent service such as or to transfer your files. These are free services which allow you to upload large files to their servers using a web browser. The service then sends messages to your recipients with links to the files, allowing them to download the files. More information may be found on their web sites.
