Hi Christoph, I have followed this section and have 2 questions/observations. 1) only one of the certificates for one domain is defined here in smtpd_tls_cert_file and smtpd_tls_cert_key so it will be used for encrypting all the smpt traffic disregarding the domain it will go out from? Would it be possible to have this for each domain separately somehow ?

I have seen taht the email that are sent by the server are not encrypted , so I suggest to add: smtp_tls_security_level = may in the configuration to have the outbound connection encrypted to ( in the config only the inbound connections are encrypted if the inbound server can do it ).
Notice if your clients are using SSL/TLS as protocol and not STARTTLS the option smtpd_tls_wrappermode=yes Is important. I struggled 2-3 hours with Thunderbird. With postfix in double verbose mode I found the reason.
With the relevant text stating: This is a feature that forces every address that can be looked up in $smtpd_sender_login_maps (apparently all of your valid local recipients?) to authenticate in order to be used as a sender. This feature is not usually suitable on a server that handles anything other than initial mail submission.
smtpd_sender_login is pretty restrictive. But most webmail providers I came across seem to enforce that you send only as yourself and not anyone else in the domain. If that causes trouble with virtual_aliases please see the first comment on this page to reflect forwarding and this restriction.

Hi. Thanks for the guide. If I want to relay my mail through my isp, what should I include? I am pretty sure I need to fill in relayhost and port (587) and authentication. Should this be done with password authentication or certificates? Can this be done by adding the following? postconf smtp_tls_cert_file=/etc/letsencrypt/live/webmail.example.org/fullchain.pem postconf smtp_tls_key_file=/etc/letsencrypt/live/webmail.example.org/privkey.pem postconf smtp_tls_security_level=may
I added a check so I can send mail with alias emails that are related to my account. You have to use unionmap for postfix or UNION for mysql. smtpd_sender_login_maps=unionmap:mysql:/etc/postfix/mysql-email2email.cf,mysql:/etc/postfix/mysql-virtual-alias-maps.cf smtpd_sender_restrictions = reject_unknown_sender_domain,reject_sender_login_mismatch
Even in 2013, there are still services that continue to offer the deprecated SMTPS interface on port 465 in addition to (or instead of!) the RFC-compliant message submission interface on the port 587 defined by RFC 6409. Service providers that maintain port 465 do so because older Microsoft applications (including Entourage v10.0) do not support STARTTLS, and thus not the smtp-submission standard (ESMTPS on port 587). The only way for service providers to offer those clients an encrypted connection is to maintain port 465.
If you use Amazon SES in an AWS Region other than US West (Oregon), replace email-smtp.us-west-2.amazonaws.com in the preceding command with the SMTP endpoint of the appropriate Region. For more information, see Regions and Amazon SES.

If you use vsftpd asFTP server on your system this service will not be run by inetd/xinetdafter the installation of the ISPConfig system but by theispconfig_tcpserver which comes with the ISPConfig system. This happensin order to make sure that vsftpd can handle one Anonymous-FTP accountper IP address. Under inetd/xinetd vsftpd can only handle oneAnonymous-FTP account per server even if the server has multiple IPaddresses. In order to avoid this disadvantage compared to the proftpdserver the ISPConfig system uses the ispconfig_tcpserver.
Hello very good tutorial, but I want to ask why the imap port does not work, the smtp with port 587 works perfect but the imap 143 does not work, RainLoop says MailSo-Net-Exceptions-SocketReadTimeoutException (NetClient.php 514), I appreciate if you have any idea what may be happening and how it can be solved, thanks
Very wonderful tutorial. It is very easy to follow. Please help me, after I completed setting postfix, dovecot configuration failed. Tried to fix. But now I can send or receive any email. The msg smtp connection failed shows up. What did I miss.
Hint: The procedure that is described below is for ISPConfig versions
According to a description in one of my older posts, ispconfig 3.1 + Lets Encrypt + Postfix / Dovecot + PureFTPD in english we can take advantage of the fact, that ISPConfig is just setting symlinks on certificates in the web directory and then just fires up a cron to renew your certificates.
NOTE: if you intend to use numeric addresses, or so-called addressliterals per the SMTP standard, write them in proper SMTP syntax, forinstance --smtpaddress "[192.0.2.6]" or --smtpaddress"[IPv6:2001:DB8::6]".
fetchmail also supports authentication to the ESMTP server on theclient side according to RFC 2554. You can specify a name/password pairto be used with the keywords 'esmtpname' and 'esmtppassword'; the formerdefaults to the username of the calling user.
