First take a look to see what hosts Mail is contacting. You can run the nettop tool, then type c to collapse the listing, find Mail in the list, and then type e to expand the list to see the hosts Mail is communicating with. Once you know the host name in question, you can easily watch the data Mail is transferring with something like: sudo tcpdump -s 0 -A -i en0 host my.mail.host -- E-mail sent to this address may be devoured by my ravenous SPAM filter. I often ignore posts from Google. Use a real news client instead. JR

That was fruitful. The guilty connection is gmail imap. Whether the traffic originates at Gmail (sending IMAP and Mail replying or Mail sending to Gmail and Gmail replying) is less clear. It's also not clear which Gmail account (of 3) that the log is recording from. (The other Gmail log files are relatively small and have 30 minute intervals - the guilty one logged over 15 MB of reports - from last night to this am - and the computer was in Sleep for most of that time). The one POP account is being pinged on schedule (30 minute intervals). READ Nov 26 08:38:27.924 [kCFStreamSocketSecurityLevelTLSv1_2] -- host:imap.gmail.com -- port:993 -- socket:0x610000111110 -- thread:0x608000111180 258.232 OK IDLE terminated (Success) Above is repeating several times per second - and of course Mail is replying to it. (or v-v). I've changed some settings on the GMail end - probably won't do much to improve this. But starting a fresh log set - maybe find out what "kicks" this off. -- She hummed to herself because she was an unrivaled botcher of lyrics. -Nick (Gone Girl), Gillian Flynn.

This is not a fault. I never said IMAP communication was a fault. This constant 1 - 4 kB/s certainly is unusual. Right now, for example, it is 0 in and out with occasional bursts for this or that.
