Check retval of event_add() calls
Reduce frequency of userdb atime updates by not updating until idle time reaches more than half of user timeout value, otherwise privsep server can get very busy causing locked userdb
Do not care about multiple matches of IP addresses in arp cache on OpenBSD either
Performance and code reuse improvements, simplifications
Separate mail/mails to pop3/pop3s/smtp/smpts for statistics
Write connect logs to syslog too, for statistics
Fix log lines for statistics, remove fds from err logs
Add DEBUG_PROXY directive around all log_dbg_level_printf() and related lines
Log stats to syslog, similar to error logs, so that it is simpler to rotate and parse
-O w/o -g is failing bufferevent_socket_connect for parent dst, so either enable -O w/ -g, or disable -O w/o -g (-O2 is failing too)
Refactoring
Check if srv_dst bev is NULL or not: Since both eventcb and writecb for srv_dst are enabled, either eventcb or writecb may get a NULL srv_dst bev, causing a crash with signal 10.
Remove unnecessary evutil_closesocket() calls, they could close the fds twice, causing conn stalls
