--- Comment #1 from Jeremy Harris <jgh146exb@wizmail.org> ---
While the version listed on this bug is 4.96+, a timeout was added for 4.95
which should addressed the situation given. Please verify that you are
actually running 4.96.

I haven't had much time to review the timeout from that commit, but at first
glance, it seems that the timeout is only referenced in the internal loop,
while the outer loop does not:

----------------------------------------------------------------------------------
do
{
do
{
retmore = read(fd, (uschar*)&hdr + ret, size-ret);
} while (retmore == -1 && errno == EINTR && !had_command_timeout);
if (retmore == -1)
goto proxyfail;
ret += retmore;
DEBUG(D_receive) debug_printf("PROXYv2: have %d/%d required octets\n", ret,
size);
} while (ret < size);

}

----------------------------------------------------------------------------------

After some additional testing, it seems that referencing the
had_command_timeout variable in the outer loop will fix this issue.

----------------------------------------------------------------------------------
do
{
do
{
retmore = read(fd, (uschar*)&hdr + ret, size-ret);
} while (retmore == -1 && errno == EINTR && !had_command_timeout);
if (retmore == -1)
goto proxyfail;
ret += retmore;
DEBUG(D_receive) debug_printf("PROXYv2: have %d/%d required octets\n", ret,
size);
} while ((ret < size) && !had_command_timeout);

}
