NAME
unfreezemail - move a message from the error queue back to the input
queue
SYNOPSIS
unfreezemail [-D [-f]] [-i] [-n] [-m] [-v N] message-queue-id ...
DESCRIPTION
Unfreezemail safely reprocesses the specified error queue files. This
script can be used to retry messages that were frozen in the error
queue by smail during the time when a configuration error existed, for
example.
Note that if the message is already a bounce message (i.e. is from
‘‘<>’’ or ‘‘<+>’’), or if the error which caused the message to be
frozen in the first place has not yet been repaired, then another fail‐
ure to deliver the bounce will simply move it back into the error queue
immediately. You can then use the -D option to delete the re-frozen
message.
WARNING: Unfreezemail will cause the message delivery to be re-
attempted to all addresses which had previously failed. If this is not
intended then the message and/or its corresponding log file will have
to be manually edited.
OPTIONS
-D Delete the frozen message instead of re-queueing it.
-f Force the deletion. By default each file must be confirmed
before it is deleted.
-i Confirm each re-delivery attempt interactively.
-m Call mailq before re-attempting delivery.
-n Do not immediately start a runq process to re-attempt delivery.
-v N Tell the runq to be verbose when re-processing the message file.
