Syntax: UN(ERASE) [ <call> | <board> ] [<range>]

Makes erased mails visible again. Only with the PURGE command the mails
really will be erased. After PURGE you can not make the mail visible again.
With the ERASE command mails only are marked to be erased and made invisible.
To make the mails readable again you have to use the UNERASE command.
You can specify a range like at the commands DIR, LIST, ERASE, etc.

You can list erased mails with "DIR -KV". After the mail number there will
be shown why the mail has been deleted.
 E  - erased with ERASE command or at the "Erase mail?" prompt
 F  - mail has been forwarded to a other BBS and is therefore deleted
 K  - erased by the sysop with remote erase
 L  - erased by a remote erase
 S  - mail is erased by local sysop
 T  - mail has been transfered to another board and is therefore deleted

Example:   UN DL8MBT 1-   all erased mails of DL8MBT are visible again
