Postfix mail send issue?

Question

I am facing some issue in my postfix. I am not receiving any mail from postfix. The log file also doesn't show any error log. Log file is normal. On further analysis I found mail is going to incoming but not in active folder of postfix. Only one thing I found in maillog file:

postfix/cleanup[30369]: warning: database /etc/postfix/virtual.db is older than source file /etc/postfix/virtual

Rest of maillog file was normal.

I am able to find the issue. can any one help on this.

Answer 1

Run:

postmap /etc/postfix/virtual

Then restart postfix.

The warning means that you have a text version and a hashmap version of the virtual file. The text version is the human readable one that you edit, then you build a hashmap of it using postmap and that's what postfix reads. It's just telling you that you may have made a change to the human readable one and forgot to create a new .db of it.
