Hello List, sometime age my msmtp imap connections just stopped working. Investigating the cause, I checked quite a lot of things, and came across the ping "100% package loss" problem: With /etc/resolv.conf ,---- | # Generated by resolvconf | domain Speedport_W_xxxxxx | | nameserver 192.168.2.1 | nameserver fe80::1%ens34 `---- this works ,---- | $ drill @192.168.2.1. www.google.com | ;; ->>HEADER<<- opcode: QUERY, rcode: NOERROR, id: 36946 | ;; flags: qr rd ra ; QUERY: 1, ANSWER: 1, AUTHORITY: 0, ADDITIONAL: 0 | ;; QUESTION SECTION: | ;; www.google.com.

Even when I put Googles DNS Servers in my /etc/resolv.conf, it would not work. So what could be the problem here? TIA -- cheers, Thorsten
