When internet connectivity goes down at times, local users get smtp time-out messages (server not responding). I figured the cause of this message is that by default sendmail does initial dns lookups on all messages it recieves and in case of internet connectivity being down, it is not able to do so and produces this message. so I configured sendmail in defered delivery mode so that it should queue every message and should not do dns lookups and accept emails from local users in case of internet connectivity being down. However I figured that in defered delivery mode it does not implement anti spam configuration in access map. When I change delivery mode to defaulot background or queue-only then it looks access maps and prevents mail spamming. Is there anyway to make access maps work in deferred delivery mode. or any other configuration in which sendmail implements anti spam rules and also does not do initial dns maps so that email could be queued by sendmail even when it cannot reach internet. thanks arslan.
