Yes, that's also how it's intended to work.

I do have the trivial 127.0.1.1 myhostname.zugschlus.de myhostname line in my /etc/hosts and my exim does the right thing, like echo test | mail root getting correctly qualified to m...@myhostname.zugschlus.de and r...@myhostname.zugschlus.de. Is your "myhostname.mydomain.local" the literal host name? If so, are you actually using the .local TLD or is that just obfuscated? Please consider using a different TLD as .local may cause interference with avahi (the .local TLD is reserved for use with mDNS). > (by the way: static IP address means manually-assigned IP address only > or also DHCP-assigned IP address that is always the same because is > based on a static map on DHCP server?) I used the wrong word. I just meant having the actual IP address in /etc/hosts instead of the 127.0.1.1 placeholder, but that's not the problem since things work fine on my local system. > - /etc/mailname set with FQDN, "Other destinations for which mail is > accepted" during dpkg-reconfigure leaved blank, hostname set as > myhostname.mydomain.local, it states: > 08:56:56 3363 local_part=username domain=myhostname.mydomain.local > 08:56:56 3363 checking domains > 08:56:56 3363 myhostname.mydomain.local in "@:localhost"? yes (matched > "@") > > so it right matches "@" I do have the FQDN set in /etc/mailname. See https://wiki.debian.org/EtcMailName?highlight=%28mailname%29 for the current (sad) state of /etc/mailname and its documentation in Debian.
