EOU-specific limitations on mail lists:

Some limitations apply to Majordomo mail lists at EOU:

In response to incidents of spamming/abuse, lists of all mailing lists are not available.
In response to incidents of spamming/abuse, only the owner of a list can generate a listing of its members.
Use the passworded form of the "who" command: &nbsp&nbsp approve password who list-name
Attachments in proprietary formats should be avoided when plain text suffices. Because the total size limit on a Majordomo message is 40K by default, only very small attachments will get through. To distribute large materials, put together your own list in your client's addressbook, or, better yet, place the material on a web site for distribution (and send the link to the mail list if desired).
The following attachment types are deemed dangerous by Microsoft and are blocked by EOU:
"ade", "adp", "bas", "bat", "chm", "cmd", "com", "cpl", "crt", "exe", "hlp", "hta", "inf", "ins", "isp", "js", "jse", "lnk", "mdb", "mde", "msc", "msi", "msp", "mst", "pcd", "pif", "reg", "scr", "sct", "shs", "shb", "url", "vb", "vbe", "vbs", "wsc", "wsf", "wsh"

We also block "zip" and "rar" files to prevent virus propagation.
See http://support.microsoft.com/support/kb/articles/Q262/6/17.ASP
This applies to all mail to eou.edu, not just Majordomo. You can send such attachments by changing the file type to something unrecognized, like "zzz".
