Details:

The strnlen() function returns strlen(s), if that is less than maxlen, or
maxlen if there is no null terminating ('\0') among the first maxlen
characters pointed to by s.

We cannot detect if server argument is too long with strnlen() because len
never greater than SMTP_MAX_SERVERNAME_LEN.
Switch back to strlen() instead.
