[Cod-bugs] Flooding our logs :(

[Saulius Gražulis]

Hi, folks,

your connection makes multiple attempts to send SSL packets that our 
server deems incorrect, and these packets flood our logs:

The log becomes about 23M for a single day :(

Could you please limit your requests to a single IP to no more that 
10-20 requests? Our server is "lists.crystallography.net" (158.129.170.77).

Thank you for your understanding.

Sincerely yours,
Saulius
