It's not roundcube its the smtp server you are using. You will need to bind that to the specific IP address you want it to use.

Without that, generally it will bind to all available addresses. Thus when the virtual adapters are down it only binds to the 'real' IP. When the virtual adapters are up it will bind to them all and will use whichever is available first when sending.

Hello,

I have a problem with round cube and my network.

I have 3 ips and the OS is Linux Debian:

- eth0 - 46.55.253.244 - Ethernet
- eth0:0 - 46.55.253.245- Ethernet (Virtual)
- eth0:1 - 46.55.253.246- Ethernet (Virtual)

When adding the virtual networks round cube is connecting and sending e-mails from x.x.x.245. Pls see the following log:

Apr 10 11:12:05 ns1 dovecot: imap-login: Login: user=<office@pcexpert.bg>, method=PLAIN, rip=46.55.253.245, lip=46.55.253.244, mpid=11257, session=<9wjJ+xww5gAuN/31>

When the virtual networks are down, then roundcube works fine:

Apr 10 11:32:05 ns1 dovecot: imap-login: Login: user=<office@pcexpert.bg>, method=PLAIN, rip=46.55.253.244, lip=46.55.253.244, mpid=11257, session=<9wjJ+xww5gAuN/31>

 

In config.ins.php the code is:

$config['default_host'] = 'pcexpert.bg';

When the code changes to $config['default_host'] = 'localhost' , roundcube is connecting 127.0.0.1, but sending e-mails from 46.55.253.245 

Log:

Apr 10 11:32:05 ns1 dovecot: imap-login: Login: user=<office@pcexpert.bg>, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, mpid=11257, session=<9wjJ+xww5gAuN/31>

 

Pls advise, how can roundcube connect and send e-mails to the real ip 46.55.253.244, when having vitual networks.

 

Best Regards,

Svilen
