I run a small "C1" server on scaleway.com without any fancy experiments or configurations applied - just a straight vanilla ArchLinux armv7h install - which I keep updated regularly using "pacman -Syu". It seems that a recent update, possibly sometime the past few weeks, has removed sendmail(1) from the system rendering all mail agents relying on sendmail(1) (such as mail/mailx, mutt, php etc.) unable to send any mail out from the system:
[swn@scalewayc1 ~]$ mail -s test someone@myhostname.net
hello.
Cannot start "/usr/sbin/sendmail": executable not found (adjust *sendmail* variable)
"/home/swn/dead.letter" 6/112
... message not sent
Has anyone noticed this problem? Any fix for it? Any suggestions?
