Signal handling is identical for pop3d,imapd,lmtpd afaik. They all share the same signalhandling code from server.c and serverchild.c

SIGABRT is not handled explicitely by the code. No handler is installed. This could be os-specific. What are you running on? I've never seen a kernel logline like your's with the kernel-path specified. But all I know is linux...

In contrast to dbmail-imapd, a child process of dbmail-pop3d exits on signal 6 (SIGABRT) if the client unexpectedly drops the connection. Is this behavior intended?

syslog messages:

dbmail/pop3d[8151]: PerformChildTask(): incoming connection from [...]
/boot/kernel/kernel: pid 8151 (dbmail-pop3d), uid 65534: exited on signal

6

dbmail/pop3d[8151]: pop3_handle_connection(): error, uncomplete session
