Your mail server is probably doing a reverse IP lookup to find the real DNS name for the host your are coming from.
Some providers do NOT map this and hence this can cause a delay as the DNS tries to find one.. Solution(s), 1/. Turn off this feature in the mail server 2/. Get a reverse name assigned to your IP(s).
