Seeing a lot of this in my maillog: sendmail[23090]: STARTTLS: write error=syscall error (-1), errno=104, get_error=error:00000000:lib(0):func(0):reason(0), retry=99, ssl_err=5 Using AV-SPAM6 although not sure this has anything to do with it. 5208R fully up to date. Anybody able to enlighten me? Thanks Colin
