Hmm, what do you mean by "changes incoming emails to name@localhost"?

What is changed specifically, and what are you using to to view that? Are you using Usermin? Outlook?

Do you think you could post the full headers from an email where this occurs?

Thanks,
-Eric

for example ive got an email mbcis@mbcis.org
when it gets into postfix the email address suddenly becomes mbcis@whateverthehostnameis which is set to localhost so of course the email bounces because that email doesnt exist

thanks for that.. what should i be setting it to? as i want it to recieve more than just 1 domain

#5 Tue, 03/31/2009 - 00:36 (Reply to #4)

Joe

You should set it to the hostname you want for the system. Receiving mail for multiple domains is irrelevant; that's handled by the virtual map file (which Virtualmin manages automatically). "localhost" and similar is nonsensical for a public IP. The hostname returned by "hostname -f" needs to be a resolvable fully qualified domain name.

i had this set to fdwow.net before i changed it to localhost and every email that came in addressed to mbcis@mbcis.org would get changed to mbcis@fdwow.net...

i just set the hostname for postfix to ns4.webtastix.co.nz which points to that ip and it changes the email to mbcis@ns4.webtastix.co.nz

Howdy,

What happens if you log into your server over SSH, and you type this:

cat /etc/fstab | mail -s "A Fun Test" mbcis@mbcis.org

What I'd like to see is the email logs from that time (/var/log/mail.log or /var/log/maillog), as well as the full email contents (including the headers).

<div class='quote'>i just set the hostname for postfix</div>

What do you mean "for postfix"? I meant set your system hostname correctly! Don't set <i>anything</i> in Postfix. Postfix is not responsible for your system hostname. I'm betting you've set "myorigin", which is never the right thing to do in a virtual hosting environment. Remove that completely from your postfix configuration. You don't want it, you don't need it, and it doesn't do what you think it does (it does what you've seen: causes mail to no be delivered because no one ever configures it correctly).

Check out the forum guidelines!

also, not sure if this matters but emails are constantly delievering to root successfully for cron jobs

Alright, do you think one of us could just log in and take a look?

Something's definitely going on that we're overlooking here in the forums, but it'll likely stand out a little quicker if we were looking at your system.

If that's okay, you can send your root login details to:

joe@virtualmin.com
eric@virtualmin.com

Also, be sure to include the following in the message body:

1. A link to this forum thread

2. An email address that should work, but isn't

Thanks,
-Eric

Cool thanks.

I sent a message to your reply-to address there -- I'm holding up on making some changes until I hear back from you on that :-)

Thanks!

Okay, after making only a few small tweaks, the main issue I see going on here is a hugely slow ClamAV process.

The system load was fairly huge, and some clamscan processes had been running for several hours.

And every time we sent a test message, it got just a little worse :-)

So it's not that it isn't delivering email. It was just delivering it so slowly, that it just appears as if it isn't :-)

There's some additional information on that problem, and the solution, mentioned in here:

http://www.virtualmin.com/forums/help-home-for-newbies/email-not-being-d...

Essentially, you need to enable the Debian volatile repository, and pull down the clam related packages from it to replace the ones you currently have installed.

Once you do that, I think you'll notice a pretty big performance difference :-)

Also, though, you may want to enabling the "Server Scanner (clamdscan)" in Email Messages -> Spam and Virus Scanning for additional performance improvements.

You have a gig of RAM, that should be plenty for the Clam daemon.

Feel free to yell if you have any questions on any of the above.

Have a good one!

wow! thanks for that :) you must of also changed a few things as even emails sent from my website come from the right address now :D
thank you so much

<div class='quote'>you must of also changed a few things as even emails sent from my website come from the right address now</div>

Removing those myorigin/myhostname/etc. bits would allow things to work correctly. To quote Cheap Trick again, "Everything works if you let it." ;-)

is there anyway for now that we can just disable clamav? to test if that is the actual problem?

#21 Wed, 04/01/2009 - 19:59 (Reply to #20)

andreychek

In Edit Virtual Server -> Enabled Features, you can disable Virus Scanning for that domain.

the reason those clamav things have been sitting there may be because i forgot i had disabled those services aswel

#23 Tue, 03/31/2009 - 09:19 (Reply to #22)

AskewDread

andrey when i do that i get mail: command not found

Joe: no its setting the hostname option, i took out the myorigin option a few days ago..
the system hostname is already set correctly

#24 Tue, 03/31/2009 - 15:30 (Reply to #23)

andreychek

Okay, so lets try this:

1. First, install the mailx package, using either apt or yum, and then try this again: cat /etc/fstab | mail -s "A Fun Test" mbcis@mbcis.org

2. What is the output of: hostname

3. What are the contents of your /etc/hosts file

4. Can you attach your /etc/postfix/main.cf file?

You may have set the hostname, but something still isn't working right, as the email headers are identifying your Internet facing IP address as "localhost". Hopefully we'll discover why that is in the above information :-)
