Maybe this is the cause:
Sendmail has usually IDENT queries enabled which timeouts in 10 or 15 secs
(if the TCP connection back to clients port 113 does not lead to an
immediate connection refused). 

I have following line included in my .mc config:

define(`confTO_IDENT',`0s')dnl

which prevents your server to do any IDENT queries.


Have a nice day,
