mailq - Display the mail queue
mailq [-sort] [-batch]
mailq displays a list of all messages that have not been delivered yet. The display contains: the queue ID; sending user; the size of the message and the time the message was created; the return address, and a list of the message's recipients. If the message was already delivered or failed for some recipients, this will be indicated as well. The optional -sort sorts the list according to the messages' timestamps, oldest messages first. This may take a while if the mail queue is very large. The optional -batch uses an alternative, machine-parsable output format, one line per message: size;qid;date;user;from;[status;recipient];[status;recipient];[...] Only the superuser can view the contents of the entire mail queue. Everyone else can only see their own messages.
The 80-column limitation forced a somewhat ugly design.
