Qmail issues and tips

[lenawaii]

Hi everyone,

I have two questions, thank you for your help:

1/ Can we bind several IP address to Qmail Toaster in Kloxo MR 7? I would like to protect some Ip from being blacklisted. As you know, only one bad client acting as a spammer can destroy your IP reputation. In this way, I could isolate customers with dedicated IPs on the VPS.

2/ Can we force send outgoing mails to domains that are currently in the VPS (listed in rcpthosts)? For example, i have domain.com on server A but emails of domain.com are on server B. If i send an email from server A to postmaster@domain.com, the email don't reach Server B but get stuck on server A. What is the solution ? My goal would be to have one VPS for domains and another VPS for emails.

Best regards, Lenawaii

Kloxo-MR 7.0 create /var/qmail/control/outgoingips where every domains use different ips based on 'A record' for '__base__'.

Sadly, it's only work for smtp/smtp-ssl/submission but not work for sendmail (use by mail() function in php).

Thanksfor the reply.

I understand that domains and its emails should be in the same server to work proprely? If we use MX of another server, emails sent with PHP mail() function will not be delivered but stuck in the server hosting domains?

It's a shame because emails take much space on servers and I would have taken SSD VPS for websites and HDD VPS for emails.

Is there any fix for this issue? Is this due to Qmailtoaster or Kloxo MR7?

Mail() not depend on 'MX Record' but you need adjustment 'TXT record' for 'SPF'.

Well i found a solution to make my system work:

1 SSD VPS for domain names + 1 HHD VPS for emails of the same domain names

If mails are delivered in the first VPS, I'll copy the mails to the 2nd VPS with a cron tab and scp command.

I will test this process and tell if it works fine or not...

For the point 2/ I discovered an option in Kloxo that define Remote mail for a domain:
- Mail Hosted Remotely: remote
- Webmail URL: http://webmail.mydomain.com/
That permits to store emails of a domain on another cheaper server with more space (HDD server)
