I do have the server filtering about 75% of the spam it receives using a
technique called greylisting(*) which adds a delay.

I'm sorry about that.  I've added you to the whitelist, which will have
your mail bypass the delay.  If anyone else has a similar problem, just
let me know and I'll do the same.

(*) Greylisting (or graylisting) is a method of defending e-mail users 
against spam. A mail transfer agent (MTA) using greylisting will 
"temporarily reject" any email from a sender it does not recognize. If 
the mail is legitimate, the originating server will try again and the 
email is accepted. If the mail is from a spammer it will probably not 
be retried since a spammer goes through thousands of email addresses and 
can not afford the time delay to retry.
