  • Advice needed: SMTP Size limit problems

    HI All
    I am probably missing something but for the life of me I cannot see what it is and I was wondering if you could shed some light

    the scenario is as follows:
    4 exchange 2003 SP2 servers (3 Back end and 1 Front-end)
    1 mimesweeper smarthost forwarding to an upstream AV/AS provider
    Exchange globals are standard 10MB limits and we have a 6MB restriction on an SMTP Connector
    there are no mailbox policies in place
    there are no mailbox size limts set

    we have recently lifted the 6MB restriction on external inbound and outbound mail
    this was altered on the SMTP Connector and the Server was restarted to ensure new settings would be applied

    we are now getting rejection size from our Front End server, I have checked the Virtual SMTP Server on the FE and I cannot see where else it might be stopped

    its no doubt something painfully obvious but I cannot see the wood for the trees

    thanks in advance...
