postfix dovecot

First check your details

Now we can start as follows

Stop postfix and dovecot service
```
systemctl stop postfix dovecot
```
Use rsync command to copy the vmail directory to new location
```
rsync -av /var/vmail/ /home/vmail/
```
Note: above command will copy vmail to /home/vmail with all existing permissions.
Keep a backup of /var/vmail directory
```
mv /var/vmail /var/vamil.orig
```
Next, create a symlink to new location from old location
```
ln -s /home/vmail /var/vmail
```
Symlink creates a reference from new location to old location.
Now, start postfix and dovecot
```
systemctl start postfix dovecot
```

That’s it.

You can then test send and receipt of emails. If all looks okey, then you can delete the /var/vmail.orig folder to make the space available.
