Mail do not arrive

[sojic]

Centos 5.1 with ispconfig.

It was everything OK till yesterday. Now... mail do not arrive. I'm sending mail from another host, and I did not receive "Mailer daemon reply" that mail can not be delivered. From another side (on ispconfig hosting), I do not receive any mail.

Where is mail? Why it do not arrive to destination. And if there is problem, sender should receive "mailer daemon notification".


Thanks in advance.

I just comment this line in /etc/postfix/main.cf

#message_size_limit = 720000000

and all mails arrive.

So... How to increase message limit size? I need to receive mails more more then default (10M).

if you want to resize sending and receiving of email attachment on postfix, modify /etc/postfix/main.cf then

message_size_limit = (size you want in bytes)

then save the configuration and then command:

postfix reload

thats all

By default this line is missing.

I add message_size_limit = 720000000 and mail stop arriving.

When I comment this line, mail arriving again.

What is the problem?

Hi I think my reply wasnt posted, my internet connection got crazy.

I think you should reduce your value of message_size_limit. Its way too far from default value of 10 MB or 10240000 Bytes. Your value is 720 MB. Its too big.

then command
postfix reload
and then
/etc/init.d/postfix restart

it will surely work.
