Missing field on new mailbox insert

On line 749 there's a field name missing (format) from the insert statement to create a new mailbox, this creates a silent error and no mailbox is created.

- db_query("INSERT INTO {mailhandler} (mail, mailto, domain, port, folder, name, pass, extraimap, mime, imap, security, replies, fromheader, commands, sigseparator, enabled, delete_after_read) VALUES ('%s', '%s', '%s', '%s', '%s', '%s', '%s', '%s', '%s', '%s', '%s', '%s', '%s', '%s', '%s', '%s', '%d', '%s')", $edit["mail"], $edit["mailto"], $edit["domain"], $edit["port"], $edit["folder"], $edit["name"], $edit["pass"], $edit["extraimap"], $edit["mime"], $edit["imap"], $edit["security"], $edit["replies"], $edit["fromheader"], $edit["commands"], $edit["sigseparator"], $edit["enabled"], $edit["delete_after_read"], $edit["format"]);
+ db_query("INSERT INTO {mailhandler} (mail, mailto, domain, port, folder, name, pass, extraimap, mime, imap, security, replies, fromheader, commands, sigseparator, enabled, delete_after_read, format) VALUES ('%s', '%s', '%s', '%s', '%s', '%s', '%s', '%s', '%s', '%s', '%s', '%s', '%s', '%s', '%s', '%s', '%d', '%s')", $edit["mail"], $edit["mailto"], $edit["domain"], $edit["port"], $edit["folder"], $edit["name"], $edit["pass"], $edit["extraimap"], $edit["mime"], $edit["imap"], $edit["security"], $edit["replies"], $edit["fromheader"], $edit["commands"], $edit["sigseparator"], $edit["enabled"], $edit["delete_after_read"], $edit["format"]);

Sorry I can't generate a proper patch file.
