After a basic sending mail test, the mail did not arrived and /var/log/mail.log records the following lines:
*Jul 13 15:42:14 digitalocean postfix/qmgr: 3BDABA06EA: from=root@debian-1gb-fra1-A01.xxxxx.com.ar, size=406, nrcpt=1 (queue active) Jul 13 15:42:14 digitalocean postfix/smtp: fatal: unknown service: smtp/tcp Jul 13 15:42:15 digitalocean postfix/qmgr: warning: private/smtp socket: malformed response Jul 13 15:42:15 digitalocean postfix/qmgr: warning: transport smtp failure – see a previous warning/fatal/panic logfile record for theproblem description Jul 13 15:42:15 digitalocean postfix/master: warning: process /usr/lib/postfix/smtp pid 9561 exit status 1 Jul 13 15:42:15 digitalocean postfix/master: warning: /usr/lib/postfix/smtp: bad command startup – throttling Jul 13 15:42:15 digitalocean postfix/error: 3BDABA06EA: firstname.lastname@example.org, relay=none, delay=1016, delays=1015/1/0/0.01, dsn=4.3.0, status=deferred (unknown mail transport error) *
I understand the problem would be “fatal: unknown service: smtp/tcp”. If this is the case, I don’t know what to do in order to fix it. Would you be kind enough to help me? Thanks!
