[Exim] SMTP command timeout

Hi,

If I send big messages I receive the following error-messages in eximon:
SMTP command timeout on connection from chaos.dvz.fh-giessen.de (win2000pc) [212.201.18.85

is there a way to increase the timeout value for incomming-SMTP-Connections?
(Maybe something like the timeout for outgoing mail over lmtp.)

thanks in advance
Oliver
