NAME
mailq - Display the mail queue
SYNOPSIS
mailq [-sort] [-batch]
DESCRIPTION
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.
BUGS
The 80-column limitation forced a somewhat ugly design.
