Yes, 'mail' was installed as part of 'mailutils' on both hosts (Ubuntu), the symlink points to /usr/bin/mail.mailutils. On the "misbehaving" host, there is an additional package 'libmailtools-perl', but I guess it is not relevant: root@social:~# apt list --installed | grep mail libmailutils9t64/noble,now 1:3.17-1.1build3 amd64 [installed,automatic] mailutils-common/noble,now 1:3.17-1.1build3 all [installed,automatic] mailutils/noble,now 1:3.17-1.1build3 amd64 [installed] root@socialnew:~# apt list --installed | grep mail libmailtools-perl/noble,now 2.21-2 all [installed,automatic] libmailutils9t64/noble,now 1:3.17-1.1build3 amd64 [installed,automatic] mailcap/noble,now 3.70+nmu1ubuntu1 all [installed,automatic] mailutils-common/noble,now 1:3.17-1.1build3 all [installed,automatic] mailutils/noble,now 1:3.17-1.1build3 amd64 [installed] _______________________________________________ Postfix-users mailing list -- [email protected] To unsubscribe send an email to [email protected]
