HowTo AntiSpam for "Beginners"

Hi, its been a journey the last few weeks and i certainly learned a lot about postifx and mail delivery in general. Let me take this oppourtunity to say thank you to all the people on the mailing list who sacrifice some of their time on a daily basis to help others. I am sure it can be really

Cert hostname does not verify...

Hi, another weekend and another chance to spend a little bit of time with postifx. :) Today i tried to get tls to work and there is one thing (again) that i probably didn`t do right, or is at least confusing to me. Lets assume the FQDN of the server postfix is installed on is, myserver.mydom

Re: Postfix + Dovecot and the purpose of LMTP

Thank you very much Wietse and Robert. :) Dennis Am 06.01.2016 um 19:55 schrieb Wietse Venema: The main difference is that with LMTP, Dovecot is in complete control over the message store: how messages are stored, how they are retrieved, per-user filters, per-user quotas, and so on. It makes a

Hey guys, i hope i am not bothering you guys lately with my rather stupid questions about postfix on the mailing list. There are tons of guides and how-tos out there and of course i try to look for answers there first but apparently, there are so many different ways of how things can be done, i

Virtual_Users for single domain

Hey guys, i want to learn more about Postfix and mail servers in general. This is more out of curiosity and personal interest, i am not a postmaster or anything. :) I purchased the Book of Postfix a while ago and read through a few chapters. I am sure most of it is still valid but on the other

myhostname = ptr?

Hey there, i read many times that 'myhostname' in the postfix configuration should be the same as the ptr and some say even the same as the mx record. So i played around with it a little bit and figured, that even though i ve set the 'myhostname' to mail.greatserver.com, whereas the hostname of
