Message Limit mistery; Exchange SBS 2003


Messages from external domain, larger than 1024KB can't get trough to user.

Already checked and disabled:
1. Virtual SMTP server - Properties - message: Message limit and session size limit disabled
2. Global settings - Message delivery - Properties - Default: All set to 'No limit'
3.  Wild guess: Mailbox store - Properties - default: Storage limits disabled

What did I overlook?

Groupsheild? Are you using a it as a smart host or a gateway? If so then your out-bound will get tagged instead of Whcih means that the recipiant server, if is is using reverse-dns is trying to find via ii-arpa address look up and not finding and assuming that is it spam.
One specific user or to any user?nothing maybe a restart will help.
also u did not mention if u ever had any restricyion on ur global settings?
Are your receiving email relayed via your ISP?  Does your Exchange server have a POP3 connection to your ISP, or are you hosting your own SMTP?

If so, then your ISP may have a 1MB limit.  Just a guess...
Problems using Powershell and Active Directory?

Managing Active Directory does not always have to be complicated.  If you are spending more time trying instead of doing, then it's time to look at something else. For nearly 20 years, AD admins around the world have used one tool for day-to-day AD management: Hyena. Discover why

Do you use and Virus or Filtering software that has message limits ( Symantec Exchange 3.x does )?
Did you check in active directory users and computers, that under properties for user, on exchange general, delivery restrictions that there aren't non default settings there?

Hay Guys,

Vahik: All users, Global settings were set once to default values but are now no limit. Server has been restarted (SBS2003)

Dstoker509: Yes recieving trough professional ADSL account trough MX relay directly. Asked ISP, no limit there

Ans-Ansdenver: Yes using Groupschield for exchange from NAI. But no limit set there

Timiano: All users are set to default, wich is no limit. I've tried to set it to nothing and 100000MB, still no luck

Alwyas get this error:< #5.2.3 smtp;450 5.2.3 Msg Size greater than allowed by Remote Host>

Strange thing, ez-srv03 is my local server not the domain I am trying to reach. How can I find out at what level this is blocked

2. vs SMTP
3. vs API
4. Exchange restricitons
5. Mailbox Restr.
6. User Restrictions

First this all was going trough a relay I made With GFI MSEC and ME but now all mail is forwarded to the Exchange Server

Really in the woods here guys



when you say not your domain, is it possible the message is being routed to another routing group via a connector? If so, there mabe a restriction on the connector.  Check your connectors.

timiano: the only connector I use is the SMTP connector provided by SBS2003 itself, and olso there are no restrictions. Or do you mean something else?

Ans: Groupschield is installed  on the SBS server itself (thus on the Exchange too) in vs API mode. This is the first Site I have trouble with email on SBS 2003, AND it is the only site I have working with Groupshield. I think I'll call NAI on this one. You probably are right.

Damn I hate NAI software... but hey, what the customer wants he'll get... more hours invoiced!
