How to change the welcome email message text in ISPConfig 3
As of ISPConfig 3.0.4, the text of the welcome email message that is sent to new email accounts is stored in the folder /usr/local/ispconfig/server/conf/mail/.
The message has this format:
————————————————————————
From: ISPConfig <postmaster@localhost.localdomain>
Subject: Welcome to your new email account.
Welcome to your new email account. Your webmaster.
————————————————————————
The first line starts with “From: ” followed by the sender email address. The second line starts with “Subject: ” followed by the email subject. The third line should be empty. All following lines are the email text.
The email text files are named “welcome_email_<language>.txt” where <language> has to be replaced with the system language like “en” for English or “de” for German language, e.g. “welcome_email_en.txt” for the english welcome email.
The customized language file should be stored in the folder /usr/local/ispconfig/server/conf-custom/mail/ so that it does not get overwritten by ISPConfig updates.

How to enable port 587 (submission) in postfix
Some internet access providers have port 25 disabled in their routers to prevent spam. If you run your own mailserver in a datacenter, you might have to enable the submission port (587) in postfix to be able to send emails from your local email client to your own mailserver.
To enable port 587, edit the file /etc/postfix/master.cf
vi /etc/postfix/master.cf
and remove the # in front of the line:
#submission inet n – n – – smtpd
so that it looks like this:
submission inet n – n – – smtpd
and restart postfix:
/etc/init.d/postfix restart
