How to set the maximum smtp line lenght with Outlook 2010 clients and Exchange 2003 SP2 server

Posted on 2011-10-11

For outgoing mail we use a spamfilter (SpamExperts). Lately some email is bounced in this filter because of maximum line lenght exceeded. The maximum line lenght in the spamfilter is set to 1000.

How can I limit either Outlook 2010 or the Exchange 2003 server to respect this limit so that my mail is not getting bounced?

I have found this: , but that is not working if you have an Exchange server.

I hope someone can help. I'm not looking to change the smart host.

Thank you,

    Line wrapping does not appear as expected when you send e-mail messages in Outlook 2003

    Change the value to
    HKEY_Current_User\Software\Microsoft\Office\14.0\Common\MailSettings - Outlook 2010

    Want to try adding both the registry values:
    wraplines -- Dword -- 0
    plainwraplen -- dword -- 0 to 998

    The problem still occurs sometimes. I can't find a pattern. I have lifted the enforcement from the spam-filter, which solves the problem, but not how I would like to see it.

    Kind regards,
