I know how to delay sending emails by the delay option but this only works up
to minutes. Is it possible to delay up to seconds level. e.g. 6:00:00 AM? (i
tried adding the seconds in the delay option but does not work)
Why? Your mail server isn't going to immediately accept at that
specific time. It will still take time to do the handshaking between
client and server. The server could be busy and not accept your message
at that time and just reject the send or queue up your mail session.
And your mail server will decide when to send, not you, and it may batch
up several e-mails, especially to the same destination domain, or have
its own reasons as to when to send your message. It doesn't instantly
send right after you send it the last byte in your message.
You're asking for a granularity that doesn't make sense considering the
e-mail protocol being used. E-mail protocols are designed for that
level of control. Hell, even chats in instant messenger clients could
have delays exceeding several seconds depending on load at the server.
