Hi,
     We are having trouble in configuring 465 port on all mail clients . We have enabled the smtps as below in the
     master.cf
465     inet  n       -       n       -       -       smtpd
  -o syslog_name=postfix/smtps
  -o smtpd_tls_wrappermode=yes
  -o smtpd_sasl_auth_enable=yes
  -o smtpd_client_restrictions=permit_sasl_authenticated,reject
  -o content_filter=smtp-amavis:[127.0.0.1]:10026

We are able to telnet 465  from localhost. Ther is no iptables rules set . But the port 465  shows as closed from outside network. Please help to resolve the issue ASAP

Thanks in advance
Murali.S

Re: Unable to access 465 port

Do you have a network firewall (the one in your LAN, not the iptables on iRedMail server) which blocks port 465?

No there is no network firewall . We were able to access  postfix/dovecot  mail server with port 465 earlier in the same server . Only after we changed to iredmail ,we are facing this issue. We have reformatted and installed iredmail on debian 10.

Re: Unable to access 465 port

Run command "netstat -ntlp", is port 465 listed?

Re: Unable to access 465 port

It's always better to use native smtp port 587.

Re: Unable to access 465 port

If no firewall, then port 465 should be accessible from other machines. Please double check firewall things.
