Topic: Tuning Postfix

Hello Zhang Huangbin,

Thanks for making iRedMail

With reference to your post:
http://www.iredmail.org/forum/post7263.html#p7263

1. Could you please let know what you mean with?

"try to list all your local users in hash files instead of storing in MySQL database,
and modify "virtual_mailbox_maps =" to use hash file"

Could you point me out in the right direction to "Use hash file"?


2. How can I disable amavisd, clamd and freshclam services
   without damaging IredMail?

3. How to create 1 user mailbox without MySQL/LDAP database?

     I want to use STARTTLS and Authentication
 
     Will this slow down the email relay's speed?   


4. I would like to have a SSL conection between my mailer and Iredmail.
   How can this be done without having a user in postfix?   

Thanks

Remove 'content-filter=' in postfix main.cf, then restart postfix service.
It's safe to disable amavisd, clamav services now.

3. How to create 1 user mailbox without MySQL/LDAP database?

Use hash file instead of mysql/ldap lookup.

P.S. May i know why you want to use hash file instead of mysql/ldap to store mail accounts?


4. I would like to have a SSL conection between my mailer and Iredmail.

Add ip address of your client in postfix setting 'mynetworks =' (file main.cf).

Thanks for your replies.

I want to speed up postfix as much as possible.

What do you recommend?

Re: Tuning Postfix

Is mysql/ldap a bottleneck on your server? What the bottleneck is?

Re: Tuning Postfix

the max speed is about  5K per hour.
How could I know what is going on?

5K per-hour is the speed on your server now? How do you get this number?

You have to analytics the server and try to finger out which component or process could be the bottleneck.

Thanks for your replies.

1. "5K per-hour is the speed on your server now"
I am testing it with a external mailer, I add its IP in mynetworks.





"I would like to have a SSL conection between my mailer and Iredmail.

Add ip address of your client in postfix setting 'mynetworks =' (file main.cf)."

I can connect the mailer with iRedMail and it relays emails.

But, I cannot get a secure connection  [STARTTLS and Authentication]
between my mailer and Iredmail.

How can I do that?






I think the bottleneck is Mysql, it is getting too much RAM.
That is why I would like to set Up a User for postfix without Mysql.

I want to use hash file instead of mysql.
But I would need to find a tutorial for that.

Thanks again
