You generally dont need a delay. It is polite to give the
mail server 1 second to take breath.
Rather assembling all the SMTP commands like EHLO,DATA,QUIT
you could simply pipe it to mail or /usr/lib/sendmail.
These programs also generate a log message for every mail sent.
All this has probably no influence on mail loss.
Check your mail system. Do you have M$-Exchange somewhere?
The SMTP gateways are famous for "swallowing" mails.
