Compliment in advance for this guide: https://www.howtoforge.com/perfect-server-debian-10-buster-apache-bind-dovecot-ispconfig-3-1/ before this I tried a lot of istruction for install mail server in debian, a lot of error during installing, and in conclusion nothing work. Thank you for every reply!
Mailman is a mailinglist software, I don't think that it is suitable for mail campaigns. Better use a software that is made for mail campaigns and newsletters.
