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=[]
