Just add them to main.cf and do a /etc/init.d/postfix reload (make sure not |
| 14 |
to include the line numbers in his examples) |
| 15 |
|
| 16 |
For the lines that reference external files, you will have to create the |
| 17 |
files and the content and the issue the command: |
| 18 |
|
| 19 |
postmap <filename> |
| 20 |
|
| 21 |
The guide puts all of the files in /usr/local/etc/postifx, but I just put |
| 22 |
the files in /etc/postfix (If you put the files in /etc/postfix instead of |
| 23 |
/usr/local/etc/postfix, make sure to change the path main.cf). I left off |
| 24 |
the spf filter since it seems that many people still have not adopted spf. |
| 25 |
Postgrey is great and I use it on my person email server, but I left that |
| 26 |
off of the business system I manage. I work for a real estate company and |
| 27 |
postgrey can delay email by 4 hours or more depending on the sending server |
| 28 |
configuration. Although no one should depend on email for speedy delivery, |
| 29 |
it is my experience that most users expect it. All of the other options |
| 30 |
have really helped a lot and cut down on spam. |
| 31 |
|
| 32 |
A couple of things to remember, each time you change main.cf or any other |
| 33 |
postfix configuration file, you need to issue the command: |
| 34 |
|
| 35 |
/etc/init.d/postfix reload |
| 36 |
|
| 37 |
to get postfix to take the new configuration changes. |
| 38 |
|
| 39 |
Also, if you change any of the external files that main.cf refrences, you |
| 40 |
need to do a : |
| 41 |
|
| 42 |
postmap <filename> |
| 43 |
|
| 44 |
and then |
| 45 |
/etc/init.d/postfix reload |
| 46 |
|
| 47 |
It is probably a good idea to tail your mail logs for a while after you make |
| 48 |
the changes just to make sure you are not blocking anything you didn't |
| 49 |
intend |
| 50 |
to. |
| 51 |
|
| 52 |
tail -f /var/log/mail/current |
| 53 |
|
| 54 |
or |
| 55 |
|
| 56 |
tail -f /var/log/mail.info |
| 57 |
|
| 58 |
depending on your logger. |
| 59 |
Also, I would recommend sending email to an account on your new system from |
| 60 |
any and all external email accounts you may have such as yahoo or gmail just |
| 61 |
for extra testing. |
| 62 |

Good Luck, |
