Seems like I rejoiced too early. I didn't get any bounces because of the following error:
2017-11-12 05:55:02 unqualified recipient rejected: <XXXXX> H=(xxxxx.xxxxxxxxx.xxxx) [127.0.0.1] (127.0.0.1 does not match any IP address for localhost) where XXXXX is a local user name which owns .fetchmailrc. So the part of fetchmail configuration which actually worked was set no bouncemail which directs error mails to the unqualified username of the user running fetchmail. And now the question is why exim can't deliver mail to an unqualified local username. See rather cryptic 127.0.0.1 does not match any IP address for localhost above. I've found several VERY old threads on the subject but no real solution. The host is IPv6-aware. # host localhost localhost has address 127.0.0.1 localhost has IPv6 address ::1 # host 127.0.0.1 1.0.0.127.in-addr.arpa domain name pointer localhost. 2017-11-12 11:56 GMT+03:00 Александр Кириллов <[email protected]>: > xxxxx.xxxxxxxxx.xxxx is a LAN hostname.
