Hi all,

My email server can't receive emails from external servers. It still can receive emails from external. Emails send internal normally.

I check postfix service and get this warning:
postfix/postscreen[1587]: fatal: error [-30986] seeking /var/lib/postfix/postscreen_cache.db: Success

The postfix config related to postscreen cache:
data_directory = /var/lib/postfix
postscreen_cache_cleanup_interval = 12h
postscreen_cache_map = btree:$data_directory/postscreen_cache
postscreen_cache_retention_time = 7d

The file /var/lib/postfix/postscreen_cache.db is still there.

Please help me to fix this issue as soon as possible. Thank you!

Any other related error log lines in Postfix log file?

Does my reply help a little? How about buying me a cup of coffee ($5) as an encouragement?
