Outgoing mail issues

Virtualmin
21

I really need to get this issue solved now, can anyone help is there some additional configuration that needs to be done if so are there any guidance notes?

22

What port do you have Outlook setup to connect on when sending an email when authentication is setup?

Also, what do these two commands show:

netstat -an | grep 465 netstat -an | grep 587
23

I’m using the standard port 25 for SMTP, the two commands didn’t return anything…

[root@babyandtoddlerworld ~]# netstat -an | grep 465
[root@babyandtoddlerworld ~]# netstat -an | grep 587
[root@babyandtoddlerworld ~]#

?

24

It doesn’t sound like Outlook is happy with the authentication methods available by default on port 25.

We can enable some additional options – what distribution is it that you’re using?

Webmin version 1.561
Virtualmin version 3.87.gpl GPL
Operating system CentOS Linux 5.6

Port 587 (Submission) should be enabled by default on a new CentOS install… you may want to make sure that saslauthd is running. You can do that by running this command:

/etc/init.d/saslauthd restart

After that, do you see port 587 in use:

netstat -an | grep 587

27

OK ran the commands got…

[root@babyandtoddlerworld ~]# /etc/init.d/saslauthd restart
Stopping saslauthd: [ OK ]
Starting saslauthd: [ OK ]
[root@babyandtoddlerworld ~]# netstat -an | grep 587
[root@babyandtoddlerworld ~]#

Please advise?

Hi Eric,

Any news on how I enable some additional options?

29

Can anyone help me with this?

30

I really need to get some help with this to finally resolve the problem can anyone advise/assist?

31

Do you have a Virtual Server that you can enable SSL for?

You can use that to get “Submission” on port 587 up and running.

So, once you pick a Virtual Server to enable SSL – go into Edit Virtual Server -> Enabled Features, and enable “SSL Website Enabled”.

Then, go into Server Configuration -> Manage SSL Certificate, and click “Copy to Postfix”.

Just to be sure that took properly, restart Postfix by running “/etc/init.d/postfix restart”.

After you do that, what does this command show:

netstat -an | grep 587

32

I have one Virtual Server set-up, does it have to run with SSL as we don’t have an SSL certificate for the domain concerned?

33

That’s okay, it’ll setup a self-signed certificate for you, you don’t need to purchase an SSL certificate.

34

OK done this is what happened after running the commands…

[root@babyandtoddlerworld ~]# /etc/init.d/postfix restart
Shutting down postfix: [ OK ]
Starting postfix: [ OK ]
[root@babyandtoddlerworld ~]# netstat -an | grep 587
unix 3 [ ] STREAM CONNECTED 1044587
[root@babyandtoddlerworld ~]#

35

Now, you’ll need to edit /etc/postfix/master.cf, find the sections relating to SMTPS and Submission, and uncomment those lines. After doing that, restart Postfix, and try running that “netstat” command again.

36

I’ve just search /etc/postfix/master.cf for ‘SMTPS’ however there is nothing found?

37

The line is likely all lower case. If you searched on upper-case only, the search wouldn’t likely see it.

-Eric

38

Nope sorry searched in lowercase for ‘smtps’ as well and still not found?

39

Well, let’s just ignore smtps for now… do you see “submission” in there?

-Eric

40

I don’t think so the only line in the file that mentions the word submission is my line 643 which is a commented line…

setgid_group: The group for mail submission and queue management
