IronPort not delivering to SMS server

Hi All,

I've just installed a C350 for a mobile operator client and they have an email to sms feature for their clients.

When IronPort delivers to the SMS server, we get a bounce message back. IronPort seems to be trying to deliver to the server but the server is rejecting the message.

When MX record is pointed directly to SMS server, it works fine. So, clearly there's a problem when IronPort is sending the message.

Here is the mail delivery error:
The following message to <2307297555> was undeliverable.
The reason for the problem:
5.1.0 - Unknown address error 552-'email size is too long'

If you send a mail to 2307297555@emtelworld.net . you should be getting the delivery error.
Do you have any idea on how we can fix it , or is IronPort modifying something ??

Looking for a prompt solution please

Thanks in advance,
Vinesh

My ironport is able to successfully deliver a message to this address.

The message in this case is most likely being bounced by the remote mail server. You can setup domain debug logs and verify this.

IronPort not delivering to SMS server

Hi,

did you send to the full address 2307297555@emtelworld.net ?
I tried to disable antispam,antivirus on incoming mail , but still this is being rejected.

Definitely, it's the receiving mail server which is rejecting the message but we don't know why.
If MX record is pointed directly to this server, it works.
They even tested this with a Symantec Appliance before and it worked.

So, i'm a bit confused on why it's not accepting from IronPort?

Please find 2 parts of a debug log.
Strangely, only mails from y-alerts@reply.yahoo.com are being accepted.

Another log below show the rejection and error message: message size too long.

Re: IronPort not delivering to SMS server

When I send a testmessage I received the following error

2307297555@emtelworld.net on 26-10-2007 9:37
The e-mail system was unable to deliver the message, but did not report a specific reason. Check the address and try again. If it still fails, contact your system administrator.
iron1.emtelworld.com #5.0.0 smtp; 5.1.0 - Unknown address error 552-'email size is too long' (delivery attempts: 0)


Can you do a telnet from the Ironport to the receiving server ?
If you have a connection can you send mail via that telnet session?

Re: IronPort not delivering to SMS server

Hello,

Yes, that's what i see as strange.

I can telnet from the IronPort to the receiving server which are on the same subnet and i can even send a message to that email address and they get it.
It's accepted and delivered without any problem.

So, i don't know why it's rejecting when we sent a normal mail through the IronPort.
There are 4 other domains in smtproutes and the others are working fine, i guess it's not a configuration problem.
I even tested with AS and AV turned off in incoming mail policies ,but same issue.

thanks,
Vinesh

Re: IronPort not delivering to SMS server

You cab try to quarantine the messages to that specific emailaddress.
If there are messages quarantined send these messages to that mailaddress and anothoter address. See what happens.

Re: IronPort not delivering to SMS server

Hi again,

i just got this from the client . this is config from the Unix receiving mail server. In fact, once it receives the mail, it breaks in in parts and send it as sms. But that's another process and we don;t touch anything on this side.


Please check with Ironport for the compatibility with Email system on unix

Re: IronPort not delivering to SMS server

Hi,

After thorough testing at customer site, we finally found out that the message were rejected because of the size which eventually came with the addition of the headers.

We disable IPAS and Sophos and tested and the mail were accepted.Although i disabled IPAS and Sophos earlier, it wasn't working. But now it's working with AS and AV OFF.

I can disable the addition of Sophos header, but can you please give me a message filter to remove IronPort Antispam headers?
We configured a specific listener to accept mail for @emtelworld.net. So, can you help on the filter specific for the listerner?

Thanks,
Vinesh
