Some incoming connections does time out if eQmail-1.11 is new compiled. It happens with connections from other mta's, more worse is that telnet connection works still fine. The environment:
- gcc >= 7.3
- glibc >= 2.27
- linux kernel >= 4.9.95 (only seen on linux yet)
Old binaries compiled with gcc-6.4 and glibc-2.25 are working fine and could be copied to the affected hosts. At least qmail-smtpd is affected, but maybe the root cause is somewhere in the glibs' socket functions (iopause, poll).
