The ">>" is a shell operator. ${run doesn't use shell by default.
An example from my config:
LIM = 100
PERIOD = 1h
WARNTO = [email protected]
DIR = /var/spool/exim
EXIMBINARY = /usr/local/sbin/exim
SHELL = /bin/sh
...
acl_check_rcpt:
...
accept authenticated = *
set acl_m_user = ${sg{$authenticated_id}{\N\W.*$\N}{}}
condition = ${if exists{DIR/blocked_users}}
condition = ${if eq{${lookup{$acl_m_user}lsearch\
{DIR/blocked_users}{1}{0}}}{1}}
control = freeze/no_tell
add_header = X-Authenticated-As: $acl_m_user
accept authenticated = *
!verify = recipient/defer_ok/callout=10s,defer_ok,use_sender
ratelimit = LIM / PERIOD / per_rcpt / user-$acl_m_user
continue = ${run{SHELL -c "echo $acl_m_user >>DIR/blocked_users; \
\N{\N echo Subject: user $acl_m_user blocked; echo; echo because \
has sent mail to more than LIM invalid recipients during PERIOD.; \
\N}\N | EXIMBINARY WARNTO"}}
control = freeze/no_tell
add_header = X-Authenticated-As: $acl_m_user
