That is what the man page for smtp reads, but from the source code for
smtp.c you can see that the timeouts are in seconds.
Extract from smtp.c :
-----------
...
...
...
case 'T': /* specify Timeout in seconds */
if (CISTREQN(optarg,"conn=",5)) {
timeout_conn = parse_interval(optarg+5,NULL);
if (timeout_conn < 10) {
fprintf(stderr, "%s: bad tcp connection timeout: %s\n",
argv[0], optarg+5);
++errflg;
}
break;
} else if (CISTREQN(optarg,"data=",5)) {
timeout_data = parse_interval(optarg+5,NULL);
if (timeout_data < 10) {
fprintf(stderr, "%s: bad data timeout: %s\n",
argv[0], optarg+5);
++errflg;
}
break;
} else if (CISTREQN(optarg,"dot=",4)) {
timeout_dot = parse_interval(optarg+4,NULL);
if (timeout_dot < 10) {
fprintf(stderr, "%s: bad data-dot-reply timeout: %s\n",
argv[0], optarg+4);
++errflg;
}
break;
...
...

I didn't try it myself
