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 Email. The following appears in its log

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, it may be unacceptable that it can only be sent.

3 solution

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