Webmail Relay Issue

We are having an issue when people try and send mail outside our domain from WebMail, it comes up with this error:
Transaction failed
554 <[email protected]>: Relay access denied
If you are using ThunderBird or Mail to send your mail, it works OK. How can I get mail sending from Webmail as well?
Thanks!

If you go into Server Admin, Mail, Relay, is your SMTP server set up to relay from whence Webmail arises? You'll want to add the domain into your local hosts.
I don't use Squirrelmail / Webmail right now, so I don't know what the source address might be. You might (will?) find this source address in the mail logs, and possibly some added details of the particular failure.
Do avoid configuring SMTP relay from any hosts and any networks outside your direct control, and do be very cautious with allowing relay from those hosts within your control.

Webmail plugins issue

Hello, everyone. I posted this in the mail forum, but got no response, so I figured it may be more of web services kind of issue. I wanted webmail users to be able to change their own passwords, so I installed the change ldap password plugin. However, now when I go to "change password" from the squirrel mail page, I get a blank page. I know I must have done something wrong during the installation, but I have been over the instructions and I can't figure out what it could be. If anyone knows anything about this, please let me know. Thanks.

BizTalk SMTP Relay Issue

We go to send mail via SMTP from all of servers, we are only able to send mail to @Dell.com addresses only.(same network)
We would not able to send to all address (like an @Microsoft.com or an @csc.com address)
I am able to send an email to all address through dot net application but not Biztalk
Please share your thoughts how to resolve the issue

I hope your .Net Application sending e-mail is NOT OUTLOOK? :D
From the BizTalk Server can you do an interactive SMTP session with the SMTP server and check if relay is permitted? If you get relay denied then very clearly the SMTP Server configuration requires modification. (the responses from the SMTP server are in
BOLD)

What is the response? do you get "250 2.1.5 <[email protected]>" or "relay denied".
Either way you should get someone who know mail & messaging involved to help to ensure that it is not a SMTP issue.
I agree with Ashwin on this NOT being a BizTalk related issue.

GWIA Relay Issue, maybe the SPAMmers authenticated...

So I was greeted with a lovely issue this morning that is really driving me nuts. My mail system was relaying messages from [email protected] using a valid user on my system (MFouch). The IP address that was sending the messages appears to be in Lagos, Nigeria (41.203.64.250). I have been combing my GWIA, MTA, and POA logs and I am not seeing any POP/IMAP/SMTP auth from that IP address. The valid local user that was being abused "C/S dos" login was getting logged but from GWIA's internal IP address. I attached a MIME copy of the message.
My GWIA agent is setup to prevent relaying. I do allow relaying from some specifically defined internal addresses. I do allow POP3 in, but only specific users can use IMAP4 (silly Android issue). I require authentication for both POP3, IMAP4, and SMTP. I ran all of the different open relay tests that I am aware of (abuse.net, mxtoolbox.com) as well as tried to relay something via telnetting to my GWIA. I have attached my current GWIA flags as well. I just added /disallowauthrelay for now as a test/precaution.
I found TID 7008712 that confused, upset, and scared me all at the same time (GroupWise Internet Agents are relaying emails when they're not suppose to be relaying.). If what this TID says is correct, how can I continue to use GroupWise?
It looks like I have stopped the trouble for now. I added /disallowauthrelay as per TID7008712 (which will probably upset a few people). I renamed my gwac.db in case there was some corruption in my SMTP access control list. I changed the abused local user's password. I renamed all of my various GWIA directories (000.PRC, DEFER, GWHOLD, GWPROB, RECEIVE, RESULT, SEND, WPCSIN, and WPCSOUT) just to give me some time to clean out all of the deferrals, send items, and to be sure there is not a message queued somewhere. Members of my team are scanning the two machines this user uses as a precaution. I have also explicitly denied 41.203.64.250 access to my network at my perimeter.
Has any of the great minds out there in the Novell Forum Land seen this before or can point out my buffoonery?
Thanks in advance,
Jeff

Hi.
I'm not quite sure where the uncertainty lies. The user yo uidentified
with the logins from GWIA has been hacked, e.g his password probably was
weak and brute forced, or gained by other means (has this user been in
nigeria recently? ;))
I also don't quite understand the outrage on the TID. It merely explains
what is logical. If someone can authenticate, he can relay. There's
nothing to be overly concerned about, except your password security. You
may want to activate intruder detection... Of course there are other
means to possibly gat to know a users password, but brute force is the
usual way...

5800 Webmail login issue

Hi.
I have a Tiscali and a Hotmail webmail account which I access via internet explorer.
Both are fine when I conect via home wireless broadband.
The problem is when I connect my 5800 to my PC with the USB cable to use the phone as a broadband modem. I can access my hotmail account this way ok and other websites. But when I try and login to my tiscali account, you enter the password and it shows you how many emails you have and when you click on an email the page refreshes back to the login page. I have contacted Tiscali and they say its a phone thing as the account is ok at there end. I have tried everything I can think of ie. updating PC suite, deleting cookies in IE, changing security settings and searching the forum etc.
Does anyone have any ideas?

Got it working. I ran the comm_dssetup.pl from /opt/SUNWcomds/bin folder on to the configuration directory of the messaging server and it fixed the issue. I used the perl script which was under /opt/SUNWmsgsr/lib before. Something strange with the old script.
Thanks.

MITM Security Registry Edit Causing SMTP Relay Issue

Hi, I recently was asked by a client to harden all externally facing web resources for a PCI compliance scan. I found a script that does most of the work by adding various protocols (TLS 1.2, SSL 3.0, etc.) and enabling them. The script however was not helping
us get past Man In The Middle (MITM) scans, so I added 2 registry settings;
HKLM\System\CurrentControlSet\Control\SecurityProviders\SChannel\
added
DisableRenegoOnServer 1
AllowInsecureRenegoClients 0
After doing this a Linux web app could not relay messages via SMTP (the only server having a problem) on port 25. So, I had to back out the changes in Exchange, but now I'm wondering how to work around this? Anyone every run into this or have any tips they
can offer? Thanks in advance.

Hi,
When the users fail to send/receive emails, are there any error message or NDR?
Try removing the “AllowInsecureRenegoServers” key and see whether the issue still persists.
Thanks,

Exchange 2003: Collab/Notification email relay issues

We use Exchange 2003 SMTP email server which is open internally and has relaying disabled.
The portal is installed on internal servers yet is having a problem sending notifications to external email addresses.
In the notification config file there are settings for email servers that have relaying disabled however this functionality doesn't work and the bug ticket for it has been opened for 4 years I'm told.
I'm wondering how smaller companies (<2000 employees) handle this issue.
Do you:
*enable relaying on your main email servers?
*setup a notification specific SMTP server?
*use a 3rd party email company?
What steps are there to reduce the threat of spammers and blacklists while still allowing email to be relayed?
I'm trying to work through this with our IT department but the idea of enabling relaying is a very touchy subject here as we have been burned by being blacklisted a few times in the past.
Thanks for any help!
Geoff

After going back and forth with Plumtree support for about 3 weeks we have solved the problem.
The problem came from a misunderstanding on what needed to be relayed. It turns out that external relaying is not needed, but internal relaying is.
Explicitly granting trust to the notification server allowed emails to begin flowing.

Relay issue?

Hi all,
I posted this earlier in the networking section but hoping someone here can assist as I think it belongs here and probably not there.
We have an existing 10.6.2 server where mail and all other services that are configured work fine. But I've had a request to implement a Windows exchange server on the same network, with a different domain name. I know I could easily host it virtually but they want exchange.
I essentially want our OS X server to pass the mail for the exchange servers domain onto it and not reject it, can this be done?
What I have done on OS X server is, created a second Primary Zone and added the IP address of the exchange server, CNAMES and an MX record.
The result is that I can send email from an OS X mailbox (domain A) to the Exchange mailbox (domain B), and the exchange server can send email.
The problem is getting email from the outside to Exchange, the OS X server sends the mail screaming back with a "relay access denied".
If I forward port 25 to the exchange server then email works, but I want both to work. Currently port 25 goes to the OS X server.
Virtual hosting doesn't work as I'm not hosting this domain on the OS X server and I'm out ideas.
Can this be done? if it can be and someone knows can you please share?
Cheers,
Dave

If I am understanding your post, the problem sounds like it is at the router/firewall layer. Do you have more than one public IP address? That is how you will be able to resolve this.
From what you wrote, you are stating that you are port forwarding SMTP (port 25) through your firewall to the OS X Server. The OS X Server has a host name of osx.yourserver.dom. And this works fine. Then, if you change the port map to point SMTP to the Windows box, with a host name of win.yourserver.dom then it works fine but cuts off the OS X Server... Is that correct?
If so, then you need network address translation and the presence of more than one public address. This may be an issue of contacting your ISP and expanding your block if you do not have more than one.
Once you have more, then you build a NAT table that maps an entire public address to an discrete private address. This allows you to port forward the same port but to different machines. Thus, you can do:
Public 80.40.20.10 ------->> port 25 ------->> 192.168.1.5 (OS X Server)
Public 80.40.20.11 ------->> port 25 ------->> 192.168.1.6 (Windows/Exchange)
Now you have two publicly available servers and you are able to properly handle the port 25 traffic.
Hope this helps and hope I understood the post.

Webmail - WRT54G issue?

Hi,
I am presently running a v5 WRT54G router with the most recent firmware upgrades. Beginning a week ago, my ability to access my university webmail has declined precipitiously. The inbox page is extremely slow to load, and the server often times out. Individual messages are the same. This issue occasionally affects my other web-based email accounts, but much less dramatically and often.
There are no known issues with the university's IT. They identified a series of potential issues, all of which I have tested and dismissed, save for my home network. These other issues included virus, XP update, firewall, and so on conflicts.
The issue is present on both my Thinkpad and my Dell desktop. I am running XP; my ISP is Comcast Cable.
Any help would be greatly appreciated. If I need to provide more info, please let me know.
Cheers, bw

Logon to router’s setup page and reduce MTU to 1365, also try triggering 25 to 110 on router… check whether it makes any difference or not…

DHCP relay issues - WLC4400 series

Hi all,
I'm experiencing some strange problems with my WLC 4400 – and hope you guys can give me a hand.
There is an issue while connecting a WLAN Client to the WLC for the first time. I pinpointed the source of the problem to the dhcp, but I wondering why this happens…
As stated above – the issue occurs only during the first time registration of a WLAN client with the WLC. If I do another registration right after the failed connection attempt, the session is established and I can start working in my network environment.
Because we use 802.1x authentication, my first idea was that there is an issue – but the authentication process completes successfully.
Another debug for the dhcp process showed an issue during the initial registration process. I'll paste an extract of the NOT working connection attempt below (DHCP DISCOVER msg and DHCP OFFER msg passed successfully – I'll focus on the DHCP REQUEST msg):

Working:
                        dhcpGateway: 0.0.0.0, dhcpRelay: 10.64.153.6 VLAN: 300
For me it seems that the WLC is not able to forward this request to the appropriate dhcp server.
Does anyone of you have an idea, why this happens? And why does this happen only during the first time login of every client? Or am I misinterpreting the debug output?!
Thx a lot in advance!
Cheers
Martin

Hi,
thx for your comment so far.
I did some additional troubleshooting yesterday and I guess I fixed the problem. The management interface was configured with two dhcp server IPs (0.0.0.0 and 1.1.1.1).
Within the Cisco documentation it is stated that the dhcp relay proxy feature uses a virtual IP 1.1.1.1.
0.0.0.0    seems to be used for the internal communication.
When I changed the dhcp address (primary & secondary) to IP 1.1.1.1 the problem was solved. We tested it yesterday evening and this morning.
My assumption is that the virtual 1.1.1.1 IP is mandatory to match the dhcp responses to the proxy relaying feature. Or the WLC uses the DHCP addresses on the management interface to forward the traffic to the appropriate feature (where 1.1.1.1 triggers the proxy feature and 0.0.0.0 is used to forward the traffic to the internal dhcp service). But this is just a guesswork – I do not know the Cisco WLAN good enough to provide a valuable explanation.

Relay issue from Unix across Exchange 2003 OWA server in Exchange 2010 environment

Hi,
I'm trying to resolve an issue. We have one Exchange 2003 server left in our environment. The rest is now Exchange 2010. We are working to decommission this server. Monitoring the SMTP logs, I am working with the various groups to get the traffic
off this server and onto the Exchange 2010 environment.
The issue we are finding is with a work flow. This Java app for eBis sends email to users. This is done correctly through Exchange 2010 and gets delivered from our HUB/CAS servers to the target user mailbox. This email has several links the user must click
for approving or rejecting requests. Upon clicking Approve, a new email window opens (we use Outlook 2010). The TO address is in the format of [email protected] Upon clicking Send, our Exchange 2010 HUB/CAS servers accept the
email, because one of our send connectors has, as address space, *.domain.corp. However, the email address being used it not an alias on any Exchange 2010 mailbox, so it appears Exchange 2010 is sending this email on to the Exchange 2003 server, which
also is an SMTP server. I *think* this server is looking at the address after @ to determine where to send it (ebisserver.domain.corp, which is valid in our DNS), and sends it on to that server, where the java "listener" program intercepts
the mail, processes it and then saves it to a file somewhere.
We are at a loss as to how to get Exchange 2010 to do this instead of Exchange 2003... once this traffic is eliminted from Exchange 2003, I can proceed with decommission of this server. Any help troubleshooting this issue is appreciated.

The only reason the Exchange 2010 server would route outbound mail through an Exchange 2003 server is that you have an SMTP Connector defined on the Exchange 2003 server that has a more specific domain than you have on the Exchange 2010 server. You
should be able to see all your Send Connectors (an SMTP Connector on Exchange 2003 looks like a Send Connector in Exchange 2010) by running Get-SendConnector.

Mail relay issue since lion server install

I upgraded (or not) my Mac Mini Server with Snow Leopard, to Lion Server.
I'm now getting mail relay errors when sending email to an account on my server from gmail.
"Technical details of permanent failure:
Google tried to deliver your message, but it was rejected by the recipient domain. We recommend contacting the other email provider for further information about the cause of this error. The error that the other server returned was: 554 554 5.7.1 <[email protected]>: Relay access denied (state 14)."
I'll post postconf -n if required.
voigtstr.com has an A name at the domain name registrar
mail.voigtstr.com has an mx record.
dig +short MX voigtstr.com returns
1 mail.voigtstr.com.
voigtstr.com and mail.voigtstr.com both point to my external ip address
any pointers?

LincNesh,
Seems the problem has been solved by Peter Rauen.
See this discussion: Mail relay SASL problem / postconf -n
I checked on my server and Peter is right. Although there are configs in /etc/postfix there is another path with postfix conf files: /Library/Server/Mail/Config/postfix
I actually only had to insert this line to main.cf there: smtp_sasl_security_options =
After a postfix reload my mails are being delivered via dyndns again.
Cheers!
