Good morning. I am planning a dovecot system with:
- 3 x glusterfs servers (with 2 volumes, 1 ssd for short term mail, and 1 with bigger hdd for long term archive mail)
- 1 x mysql server (another server with active replica will be added)
- 3 x mbox servers (with dovecot pop/imap/lmpt/sieve/postfix)
- 3 x dovecot proxy/directors for pop3/imap/smtp
- 4 x proxmox mail gateway for antispam/antivirus in front of smtp servers
- 1 x centralized syslog server
All have private ip addresses, and in front there is a firewall with HA_proxy to make high availability and load balancing.
My only problem now is using last_login plugin; i have configured on the mailbox servers on pop3/imap, but the ip address that is written on mysql is the proxy/director address, not the real client ip address. No results using real_remote_ip.
