Hi , Please help me, when i want to reply/send email, i got this: <localhost>: Helo command rejected: need fully-qualified hostname (in reply to RCPT TO command) How to solve this issue? I have attached postconf data
You have myhostname=localhost. That is not going to work. Maybe you need to redo the e-mail server setup? Or use ISPConfig, that is easier to setup. Link in my signature.
When posting in the non-ISPConfig forums, it's assumed you're not using ISPConfig, or at least that the issue is unrelated; I'll move this thread. Change the myhostname line in /etc/postfix/main.cf. I would guess that /etc/hosts is also incorrect, and likely what lead to postfix being misconfigured. No, that's fine, assuming it's the correct server name. Change your main.cf and hosts file so they all agree.
Hi Taleman, I have tried to follow instruction on this url.. https://www.howtoforge.com/how-to-install-an-email-server-with-ispconfig-on-debian-10/ But i am failed... it is my bad.. I am using ubuntu 20.04 .. i will try it again.
Hi Jesse, I have updated : - main.cf for myhostname to server1.appindowebcity.com -- /etc/hosts to 127.0.0.1 server1.appindowebcity.com then reboot server I am got another error , smtp server failed..
Refer to the perfect server guide you installed from for what the hosts file should look like, or the tutorial on using the autoinstaller if that's what you used. Also check that /etc/hostname is correct, I forgot to mention that one.
Hi Jesse, Thanks for your help... I have able to send to recipient.. and i have installed recipient server also with ispconfig.. But why it is not receiving , and the next day i got failed report : Host or domain name not found. Name service error for name=mail.listrikkita.com type=A: Host not found i will try to add A record for mail.domain.com also..
The reason is exactly what you posted, no A record for mail.listrikkita.com, and the solution is to add the A record as you mentioned.
