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
