No, no delays. The sending server knocks frequently to get me my mail,
but only one after another.

After resetting everything yesterday, I've again hanging connections,
but only two for now:
2006-03-20 11:01:16 SMTP connection from [151.155.5.143] (TCP/IP
connection count = 1)
2006-03-20 11:55:22 SMTP connection from [151.155.5.143] (TCP/IP
connection count = 2)

Yeah, that would be a way. But since this isn't a mission critical
server, I can live with this problem until I find out, *why* it happens.
And I think Heiko's point is a good one.
