So I say this is an issue because errors are logged in the imap4 log file, but it doesn’t seem to break anything.
Here is a snippet of my log file with just the IP address and emails changed:
tcpserver: pid 6794 from 2601:xxxx:xxxx:xxxx:xxxx:xxxx:xxxx:xxxx
tcpserver: ok 6794 server.myserver.com:2607:xxxx:xxxx:xxxx:xxxx:xxxx:xxxx:xxxx:993 :2601::xxxx:xxxx:xxxx:xxxx:xxxx:xxxx:xxxx::58652
INFO: Connection, ip=[2601::xxxx:xxxx:xxxx:xxxx:xxxx:xxxx:xxxx]
vmysql: error creating table 'relay': Table 'relay' already exists
vmysql: sql error[7]: Data too long for column 'ip_addr' at row 1
INFO: LOGIN, user=bob@aol.com, ip=[2601::xxxx:xxxx:xxxx:xxxx:xxxx:xxxx:xxxx], protocol=IMAP
When an IPv4 connects it looks like this:
tcpserver: pid 8727 from xx.xx.xx.xx
tcpserver: ok 8727 server2.justechnology.com:::ffff:yy.yy.yy.yy:993 :::ffff:xx.xx.xx.xx::59326
INFO: Connection, ip=[xx.xx.xx.xx]
