Email delivery fails [{LRT=};{LED=550 5.2.3 RESOLVER.RST.RecipSizeLimit; message too large for this recipient};{FQDN=};{IP=}]

    Question

  • Hi All,

     We seem to encounter email delivery issue when the email is more thatn 35+ MB. Exchange 2013 with MBX/CAS and Edge servers.

    On the Mailbox
    C:\>get-transportconfig
    MaxReceiveSize                                              : 25 MB (26,214,400 bytes)
    MaxSendSize                                                 : 100 MB (104,857,600 bytes)

    C:\>get-receiveconnector | ft name, maxmessagesize
    All connectors including default are set to 100 MB

    C:\>get-sendconnector | ft name, maxmessagesize
    All connectors including edge sync are set to 100MB

    On the edge server

    C:\>get-transportconfig
    MaxReceiveSize                                              : unlimited
    MaxSendSize                                                 : 100 MB (104,857,600 bytes)

    C:\>get-receiveconnector | ft name, maxmessagesize
    All connectors including default are set to 100 MB

    C:\>get-sendconnector | ft name, maxmessagesize
    All connectors including edge sync are set to 100MB

    The entire transport pipeline has been configured with 100 MB max size, but the email more than 35+ MB fails to deliver

    C:\>get-sendconnector | ft name, maxmessagesize
    All connectors including edge sync are set to 100MB

    The entire transport pipeline has been configured with 100 MB max size, but the email more than 35+ MB fails to deliver

    The max send and receive should match, so make them both 100MB

    :\>get-transportconfig
    MaxReceiveSize                                              : 25 MB (26,214,400 bytes)
    MaxSendSize                                                 : 100 MB (104,857,600 bytes)

    I assume the messages failing are ones coming or going to the internet?

  • David is right,

    User dont have rights to accept message more then 25 MB, increase the  MaxReceiveSize & Check.

    If user is external read the NDR report and check "Generating server" in NDR Report. U will get server name from where it is rejected.

  • Hi email going out to internet have the issue and we have set the outgoing message size limit to 100 MB, do we really need to set the incoming to 100 MB as well?

  • Hi channavera,

    We also need to check the user mailbox properties of send and receive size limit, that would cause the same issue.

    Run the following command:

    Get-Mailbox -Identity "the recipient fails to deliver" | Fl Name,*size

    I recommend you refer to the following article to understand how to check your email size restriction:

    Exchange 2013 Step by Step: Email Message Size Restriction
