This commit enables mailserver cycle logic by default and make a few changes: 1) Nodes are graylisted instead of being blacklisted for a set amount of time. The reason is that if we blacklist, any cut in connectivity might result in long delays before reconnecting, especially on spotty connections. 2) Fixes an issue on the devp2p server, whereby the node would not connect to one of the static nodes since all the connection slots where filled. The fix is a bit inelegant, it always connects to static nodes, ignoring maxpeers, but it's tricky to get it to work since the code is clearly not written to select a specific node. 3) Adds support to pinned mailservers 4) Add retries to mailservers requests. It uses a closure for now, I think we should eventually have a channel etc, but I'd leave that for later. |

MailServer
This document is meant to collect various information about our MailServer implementation.
Syncing between mail servers
It might happen that one mail server is behind other due to various reasons like a machine being down for a few minutes etc.
There is an option to fix such a mail server:
- SSH to a machine where this broken mail server runs,
- Add a mail server from which you want to sync:
# sudo might be not needed in your setup
$ echo '{"jsonrpc":"2.0","method":"admin_addPeer", "params": ["enode://c42f368a23fa98ee546fd247220759062323249ef657d26d357a777443aec04db1b29a3a22ef3e7c548e18493ddaf51a31b0aed6079bd6ebe5ae838fcfaf3a49@206.189.243.162:30504"], "id":1}' | \
sudo socat -d -d - UNIX-CONNECT:/docker/statusd-mail/data/geth.ipc
- Mark it as a trusted peer:
# sudo might be not needed in your setup
$ echo '{"jsonrpc":"2.0","method":"shh_markTrustedPeer", "params": ["enode://c42f368a23fa98ee546fd247220759062323249ef657d26d357a777443aec04db1b29a3a22ef3e7c548e18493ddaf51a31b0aed6079bd6ebe5ae838fcfaf3a49@206.189.243.162:30504"], "id":1}' | \
sudo socat -d -d - UNIX-CONNECT:/docker/statusd-mail/data/geth.ipc
- Finally, trigger the sync command:
# sudo might be not needed in your setup
$ echo '{"jsonrpc":"2.0","method":"shhext_syncMessages","params":[{"mailServerPeer":"enode://c42f368a23fa98ee546fd247220759062323249ef657d26d357a777443aec04db1b29a3a22ef3e7c548e18493ddaf51a31b0aed6079bd6ebe5ae838fcfaf3a49@206.189.243.162:30504", "to": 1550479953, "from": 1550393583, "limit": 1000}],"id":1}' | \
sudo socat -d -d - UNIX-CONNECT:/docker/statusd-mail/data/geth.ipc
You can add "followCursor": true if you want it to automatically download messages until the cursor is empty meaning all data was synced.
Debugging
To verify that your mail server received any responses, watch logs and seek for logs like this:
INFO [02-18|09:08:54.257] received sync response count=217 final=false err= cursor=[]
And it should finish with:
INFO [02-18|09:08:54.431] received sync response count=0 final=true err= cursor=[]
