I've been trying (in vain) to get postfix working on a remote server.
checking logs, i get this
Apr 14 20:08:49 mail postfix/smtpd[416]: warning: no entropy for TLS key generation: disabling TLS support
Apr 14 20:08:49 mail postfix/smtpd[416]: connect from unknown[193.56.29.28]

Apr 14 20:08:51 mail postfix/master[320]: warning: process /usr/lib/postfix/bin/smtpd pid 416 exit status 1
Thinking it was just a port not being open, i double checked ss -tln:

I cant seem to find the issue with it.
Here's postconf -M
spamassassin unix - n n - - pipe user=spamd argv=/usr/bin/spamc -f -e /usr/bin/sendmail -oi -f ${sender} ${recipient}
smtp unix - - n - - smtp
smtp inet n - y - - smtpd -o content_filter=spamassassin
submission inet n - y - - smtpd -o syslog_name=postfix/submission -o smtpd_tls_security_level=encrypt -o smtpd_sasl_auth_enable=yes -o smtpd_tls_auth_only=yes
smtps inet n - y - - smtpd -o syslog_name=postfix/smtps -o smtpd_tls_wrappermode=yes -o smtpd_sasl_auth_enable=yes
proxymap unix - - n - - proxymap
and postconf -n:

Can someone maybe point me in the right direction to look next?
Edit: After running postconf upgrade-configuration, i am now able to connect over STARTTLS, but am unable to send emails
Running mailq on the machine shows that there is mail in the waiting line, but it says the mail system is down. I'll keep poking around.
