] void find()
] {
]        [...]
]    if((fptr=fopen("maillist.txt","r"))==NULL) {
]        [...]
]    fscanf(fptr,"%s %s %s %s %d", addr_info[t].name, addr_info[t].street, addr_info[t].city, addr_info[t].state, addr_info[t].zip);

    Notice that here in find(), you are opening the file for read and doing
FORMATTED input.

] void save()
] {
]         [...]
] if((fp=fopen("maillist.txt","wb"))==NULL) {
]         [...]
] if(fwrite(&addr_info[i],sizeof(struct addr),1,fp)!=1)
]         [...]
] }

    But here in save(), you are opening the file for write in BINARY mode
and doing UNFORMATTED output.
    You need to change the open and read in find() to unformated, binary
input as you have below in load().

] void load()
] {
]         [...]
] if((fp=fopen("maillist.txt","rb"))==NULL) {
]         [...]
] if(fread(&addr_info[i],sizeof(struct addr),1,fp)!=1) {
]         [...]
] }
