There's no need to involve sendmail at all (on the receive side)
for that.  Depending on the MUA the OP might need one for sending --
some MUAs only support sending via SMTP, not by fork/exec sendmail.

AFAIK there is no need for one MTA (fetchmail) to invoke another
MTA (sendmail) just to get to a third mail agent[*] (procmail).
Have fetchmail invoke procmail directly.

[*] I don't remember offhand whether procmail is considered an MTA
    or an LDA, and for this analysis it doesn't matter.
