Re: Interface aliases and sending mail from postfix
I didnt' mention that but there's an extra interface in this system connected to the local network. When smtp_bind_address is set to the public IP and I'm trying to send something from LAN I get the log message: Jun 22 11:44:32 server emaster_postfix/smtp[6940]: D6AC76802D: to=exam...@example.com, relay=192.168.1.10[192.168.1.10]:10024, delay=0.12, delays=0.12/0/0/0, dsn=4.4.2, status=deferred (lost connection with 192.168.1.10[192.168.1.10] while receiving the initial server greeting) smtp_bind_address doesn't accept two IPs, local and public. Is there any other solution? 2010/6/22 Robert Schetterer rob...@schetterer.org: Am 22.06.2010 10:40, schrieb nunatarsuaq: I'm using chroot environments as a form of virtualization of two mail systems.

Re: Interface aliases and sending mail from postfix
Actually I have two mail/www/ftp systems for two different domains on a single piece of hardware. Instead of using a virtualization I chose chroot as a more efficient method of using system resources and a way to separate two independent servers. The hardware has two network interfaces, one connected to the internet and another connected to the LAN. It allows to limit external bandwidth and allow for high-speed connections between work stations and mail servers. 2010/6/22 Robert Schetterer rob...@schetterer.org: Am 22.06.2010 10:40, schrieb nunatarsuaq: I'm using chroot environments as a form of virtualization of two mail systems.
