This is my current layout.
- GPL licence
- Holding mailBox (for domainA, domain B)
Reason separate box, is due to mail server required more cpu/bandwidth/diskspace and has list a big groups of users.
A/CNAME for websites, point to box 1
Respective MX Records point to box 2
I tested websites and smtp/pop run beautifully. The problem now is webmail - usermin.
How to I configure http://webmail.domainA.com will point to usermin on Box 2 with URL unchanged? (which means I dont want to redirect the url)
*current webmail.domainA.com will redirect to https://domainA.com:20000
Any idea, some said using port fwd in iptables. But i need hear what experts says ?
Any configuration on webmin can solve this issue?
