Cannot update mailbox / var/mail/root for user root. Error writing messa

Ge: File too large

When 1 postfix is used as a mail server, of course, virtual users are not applied here, and users can only send Email but cannot accept it.

The problem with Email appears in its log as follows

Cannot update mailbox / var/mail/root for user root. Error writing message: File too large

2 the main reason for this problem is that in the postfix configuration file main.cf.default

Mailbox_size_limit = 51200000 (50m)

That is to say, when the size of the user's corresponding / var/mail/USERNAME file cannot exceed 50m, if it exceeds this value, only

Send an unacceptable situation

3 solution

The first method is to empty the user's corresponding file, of course, you can also create a script to automatically clear it.

Empty corresponding file

Echo "" > / var/mail/USERNAME

The second way is to reset the corresponding in the postfix main.cf.default configuration file

Mailbox_size_limit=51200000

Modify to

Mailbox_size_limit=0

When the value is changed to zero, there is no limit.

4 when you finish modifying the postfix maincf.deafault configuration file, you need to reload postfix

# service postfix reload

View postfix settings:

[root@mail ~] # postconf-n | grep limit

Default_process_limit = 100

Mailbox_size_limit = 0

Message_size_limit = 20480000

Smtpd_hard_error_limit = 999

Smtpd_soft_error_limit = 999

Mailbox_size is also limited in size. But how can fetching be banned when it exceeds 2G?

Baidu learned of a way to modify the postfix main configuration file main.cf

Mailbox_command = / usr/bin/procmail-Y-a $DOMAIN

Reimport the configuration file. It was a success to receive the mail again.

-Y Berkeley format mailbox, disregard Content-Length:

-an argument will set $1, $2, etc

It used to be able to send and receive, but after a period of time, you need to delete the files under / var/amavis/tmp manually (somehow you can't delete them automatically).

Except), now there is a sudden problem. I used to be able to send and receive, but I just need to delete / var/amavis/tmp the text below by hand after a period of time.

Item (somehow cannot be deleted automatically), now there is a sudden problem
