 With SMTP, the receiving SMTP server or smarthost can refuse to accept a message by returning an error code. There are two types of error: With SMTP, the receiving SMTP server or smarthost can refuse to accept a message by returning an error code. There are two types of error:
-  A temporary/transient error. These are indicated by an SMTP error code beginning with a '4'. In this case, the sender should retry later. Some possible situations where this may occur are - the receiving server is too busy, the receiving disk is full, greylisting, etc. Network errors (eg connections dropping or timing out) are also treated as this type of error. +  A temporary/transient error.

 If VPOP3 receives a permanent error, then it will not retry the message, and the sender will receive a delivery failure report from VPOP3 indicating what error VPOP3 received from the onward mail server. If VPOP3 receives a permanent error, then it will not retry the message, and the sender will receive a delivery failure report from VPOP3 indicating what error VPOP3 received from the onward mail server.

 So, a Sender Retry setting of '10,30' means that VPOP3 will retry a message 10 minutes after first trying to send it. If that fails as well, then the next attempt will be 30 minutes later, then subsequent retries will be 30 minutes later again, and so on. So, a Sender Retry setting of '10,30' means that VPOP3 will retry a message 10 minutes after first trying to send it.

-It is a good idea to have the first retry or two set to a short delay such as 5 or 10 minutes. This will mean that [[wp>|greylisting]] does not delay a message too long. It is then a good idea to slow down retries after a while, so that messages which are not going for some reason will not slow down other messages. So, for instance, **10,10,30,60,60,180** could be a sensible retry scheme.+It is a good idea to have the first retry or two set to a short delay such as 5 or 10 minutes.
