Topic: need advice on iredmail deployment

Hi Guys,

here the scenario, 1 iredmail server in HQ, 1 iredmail server in branch A, one email domain (xxx.yyy).
for example, both HQ and branch have total 5 email users, user A, user B, user C, user D and user E.
iredmail server in HQ contain all 5 users account, iredmail server in branch A contain 2 users account (user D and user E).
any email to xxx.yyy will go to iredmail HQ and iredmail branch A will pull user D and user E's emails from iredmail HQ.
user D and E will use iredmail branch A as relay and user A, B and C will use iredmail HQ as relay.
so, user D and user E will get email sent by user A, user B and user C cause all 5 users account in iredmail HQ.
user D and E can sent email to each others cause they account is in branch A iredmail but how about user D and E send email to user A, B and C, the server should reject them with unknown recipient due to iredmail branch A can't find user A, B and C, am i right?

in this case, how should i deploy the iredmail? can i configure: other users than D and E with same domain direct send to iredmail HQ? using postfix transport?

thanks for help.

regards,
ahsiangsiang

Re: need advice on iredmail deployment

your requirement is

in main office build a iredmail server 1, contain five user,a,b,c,d,e in example.com

now branch office, plan install iredmail server 2 for the user d,e use, the user would iredmail server 2 sent and receive email

seem you need to use fetch mail feature in branch office,

you install iredmail server 2 , create a domain example.com , create user d, and e, setting the two user account fetch mail from iredmail server 1.

now iRedMail have not support fetchmail. maybe you need test it.

Re: need advice on iredmail deployment

Seems easy to implement with per-user transport map and global 'relayhost' setting.

Assumed ip addresses:
- HQ: 192.168.10.10
- Branch A: 192.168.10.20

In HQ:
- Create domain xxx.yyy
- Add your users: user A-E
- Set per-user transport for user D & E, point to Branch A, e.g. smtp:[192.168.10.20]:25. So all mails arrived in HQ will be forwarded to Branch A directly (WARNING: it won't save a copy in HQ)

In Branch A:
- Create domain: xxx.yyy
- Add your users: user D & E
- Set 'relayhost' in postfix, point to HQ. e.g. relayhost = [192.168.10.10]. So that all users in Branch A will use HQ as  a relay server.

Per-user transport was already implemented. But you have to edit postfix main.cf to set 'relayhost'.

But i suggest you test it before purchasing to make sure it fit your need.
