No mail delivery

[crazy-to-bike]

Hello,

my proxmox server has a non static internet connection.
I want to deliver mails to an extern mail adress using a relayhost.

Actually postfix doesn't deliver mails.

Trying to send a mail to user@domain.de

What's / where's the problem?

Hi,
try

smtp_tls_security_level= may

instead of smtp_use_tls=yes (is obsolete).

ok i'll try.

But in my opinion the main problem ist this:

[FONT=-moz-fixed]Apr 14 20:24:22 proxmox postfix/smtp[19340]: 9AFBA1CA0B5:   to=<user@domain.de>, relay=mbox1.belwue.de[129.143.2.21]:25,   delay=2.8, delays=0.02/0.01/0.76/2, dsn=5.0.0, status=bounced  (host mbox1.belwue.de[129.143.2.21] said: 573 root@[/FONT][FONT=-moz-fixed]proxmoxdomain.de[/FONT][FONT=-moz-fixed]  unknown user account (in reply to MAIL FROM command))[/FONT]

and this:

[FONT=-moz-fixed]Apr 14 20:24:26 proxmox postfix/local[19353]: 7F0D71CA0BE:   to=<admin@proxmoxdomain.de>,  orig_to=<root@proxmoxdomain.de>, relay=local,  delay=0.01,  delays=0/0/0/0, dsn=5.1.1, status=bounced (unknown user:  "admin") [/FONT]

But I don't know what's wrong.

I think the /etc/aliases is ok.

 

[crazy-to-bike]

I solved the Problem.

"unknown user (local)" I could solve by adding a local user on the proxmox server.

"unknown user (relay)" I could solve by adding the local username as alias to the used mail account on the relayhost.

Now I'll try if backup mails will also be sent to the given external mail adress.

Hi,
for the mailaccount on relayhost you can also edit the email from the root-user?! (Datacenter -> User -> root)
