Hello, at first, i'm using howtoforge and ispconfig for years now on my private servers, its a great job you are all doing here. Yesterday i setup a new server to replace my old one. I used the howto The Perfect Server - Debian 10 (Buster) with Apache, BIND, Dovecot, PureFTPD and ISPConfig 3.2 (howtoforge.com) The server is running fine and working normally. After reading some new features in ispconfig i checked and enabled some more safety features like DKIM or SFP. I also found out that it is possible to use a delimiter "+" for my emails, this is a great feature i didn't knew until now. But now i aks if and where it is possible to change the recipient_delimiter from "+" to another one. In the /etc/postfix/main.cf i found the delimiter and changed it. But after that the emails are not delivered to the mailserver. It is only working for the "+" when i change it back. I found out / read that there is also the delimiter in dovecot, but all i found where disabled entries: I also didn't found this in the settings in ispconfig panel. All i know is that dovecot is only working with "+", but where can i change this. Also i read that dovecot should only be able to use 1 delimiter, not like postfix several ones. Is this still true or can dovecot use more delimiters in the actual version?
Hello, the "+" has the problem that some websites may reject this as username or spam bots can just filter this out. Also i want it to change it to a more user-friendly version, as an "-" is for most users a "better" thing to use. As this is only a private usage, i just want it to make it more "user-friendly" just for me But away from the reason why, the question remains the same: Where can we change the delimiter from "+" to whatever i like.
You would change the postfix and dovecot config directly, eg. try Code: echo 'recipient_delimiter = -' >> /etc/dovecot/dovecot.conf echo 'recipient_delimiter = -' >> /usr/local/ispconfig/server/conf-custom/install/dovecot_custom.conf.master postconf -e 'recipient_delimiter = +-' systemctl reload dovecot postfix reload
Hello Jesse, thats it. I can now use the "-" as delimiter. Thank you a lot and keep up the great work! Michael
A heads up for anyone else interested in recipient_delimiters, you must also specify it in /etc/amavisd/amavisd.conf otherwise amavisd will not use the correct spam policy to filter mail.
