No, it didn't annoy me, it just breaks the thread, instead of appearing 
in my 'samba mailing list' folder, your replies end up in my inbox and I 
have to manually move them to the samba mailing list folder. It is 
further compounded by having to enter the mailing list address when I 
reply to list.

You appear to be losing two minutes, as shown in log.smbd:

The time starts at 04:49:23 and ends at 04:51:27
Tracing this back in code, appears to point to protocol negotiation, 
though I could be wrong.

Why this is happening, wiser heads than myself will have to comment.
