smtpserver: when writing slow responses, don't take so long the remote smtp client regards it as timeout ...

when writing the 4xx temporary error line, we were taking 1s in between each
byte. the total line could take longer than 30 seconds, which is the timeout we
use for reading a whole line (regardless of individual bytes). so mox as
deliverer was timing out to mox as slow rejecter. this causes slow writes to
not take longer than the 30s timeout: if we are 2s before the 30s, we write the
remainder in one go.

based on a debug log from naturalethic, thanks!
