VZDump notification trying to go to root@proxmox.localdomain

[jason99]

I've got my admin email address set correctly, but every Saturday morning after the VZDump task runs, I get an undeliverable email bounce showing that the system tried to send a notification to root@proxmox.localdomain (the hostname of my server). Here is the VZDump command, as reported in the notification email:

vzdump --quiet --snapshot --compress --storage vms-backup --mailto admin@mycompany.com --all

Any clue how root@proxmox.localdomain is getting into the act? I'm growing tired of getting an undeliverable message from this every weekend.

Thanks for any input.

Hi,

cat /root/.forward

shows the right address?
The right things in /etc/aliases (root)?

You have "127.0.0.1 localhost.localdomain localhost" in /etc/hosts?

[jason99]

Thanks for replying, Udo.

Hi,

cat /root/.forward

shows the right address?

Yes.

The right things in /etc/aliases (root)?

Not sure. Here's what it says:

postmaster: root
nobody: root
hostmaster: root
webmaster: root
www: root

You have "127.0.0.1 localhost.localdomain localhost" in /etc/hosts?

Yes, that's set correctly.

check your postfix setup (/etc/postfix/main.cf)

 

[jason99]

Here it is:

# See /usr/share/postfix/main.cf.dist for a commented, more complete version

smtpd_banner = $myhostname ESMTP $mail_name (Debian/GNU)
biff = no

# appending .domain is the MUA's job.
append_dot_mydomain = no

# Uncomment the next line to generate "delayed mail" warnings
#delay_warning_time = 4h

alias_maps = hash:/etc/aliases
alias_database = hash:/etc/aliases
mydestination = $myhostname, localhost.$mydomain, localhost
relayhost = 
mynetworks = 127.0.0.0/8
inet_interfaces = loopback-only
recipient_delimiter = +

Not sure what I'm supposed to be checking. Does that look right?

 

[tom]

try adding the following line:

myhostname = host.domain.com

and use your fqdn for host.domain.com.

 

[jason99]

My server actually doesn't have an FQDN as such. It's a LAN machine on proxmox.localdomain. Should I use that with the above instructions?

 

[tom]

I assume your email server rejects the emails if you do not provide it.

 

[jason99]

So, that line should be

myhostname = proxmox.localdomain

Right?

 

[tom]

no. pls post your "undeliverable message"

the error shows that you need a DNS resolvable email domain in your main.cf. "proxmox.local" is not in public DNS, therefore its rejected.

 

[jason99]

I guess I haven't communicated very well here. I realized that root@proxmox.localdomain won't resolve to anything. My question is, how do I get the system to send email to email@mycompany.com instead, or to quit sending these emails at all?

 

[tom]

you need to configure postfix that the host is able to send emails. try reconfigure postfix with the wizard.

dpkg-reconfigure postfix

Hi there,
here is my dump question about this - even if I for example set a correct hostname on a new proxmox system, we still have to reconfigure postfix and tell it its own hostname manually, because otherwise it will default to the mentioned localhost.localdomain.
I couldn't figure out where things go sideways during installation, but on plain debian setups we usually do not have to set the postfix hostname manually.
Kindest Regards
