I tried it and I see similar delays:

Complicated theory: it's an anti-spam trick known as early talker.
Spamware tends to blast stuff out as soon as it connects, so if you
delay the banner message and the client sends HELO/EHLO before you've
sent the banner, you know it's a someone you don't want to hear from.

Simple theory: there are similar delays after EHLO and MAIL FROM, so
they seem to be severly overloaded.  Don't take it personally. That's
why your mail server can do a zillion connections at once.
