Winni Neessen	78df991399	Proposal change for #90 ... Did a complete overhaul of the senderror.go. - the list of `errors.New()` has been replaced with constant itoa error reasons as `SendErrReason`. Instead, the `Error()` method now reports the corresponding error message based on the reason. - The `SendError` received a `Is()` method so that we can use `errors.Is()` for very specific error checking. I.e. we can check for `&SendErrors{Reason: ErrSMTPMailFrom, isTemp: true}`. This provides much more flexibility in the error checking capabilities - A `isTemp` field has been added to the `SendError` type, indicating whether the received error is temporary and can be retried or not. Accordingly, the `*Msg` now has a `SendErrorIsTemp()` method indicating the same. The decision is based on the first 3 characters returned from the SMTP server. If the error code is within the 4xx range, the error is seen as temporary - A test for the SendError type has been added	2023-01-01 14:20:13 +01:00

Winni Neessen	88eb4c5663	I think it's fair that we reset the Msg.senderror to nil before we Client.Send it. ... Since the send error indicate an error during the mail delivery, in my opinion it should be reset when a re-send is initiated, so that the senderror field always represents the latest delivery error. The send error should be checked after mail delivery and before a retry is started.	2022-12-31 12:46:11 +01:00
Winni Neessen	47bff15de9	Introduction of a Msg error type as proposal for #90 ... This PR introduces the `SendError` type which implements the error interface. A new `senderror` field has been added to the `Msg` as well, so introduce this type to it. I've also added different error variables that indicate the different things that can go wrong during mail delivery. These variables can be checked for, for each `Msg` using the `errors.As` method The `Error()` method of `SendError` will return a detailed error string on why the `Msg` could not be delivered. Additionally, `HasSendError()` and `SendError()` methods have been added to `Msg`. While `HasSendError()` simply returns a bool in case a `Msg` failed during delivery, the `SendError()` will return the full `SendError` error interface.	2022-12-31 12:40:42 +01:00

James Elliott	567276d75d	feat: without noop option ... This allows disabling the Noop command during the dial. This is useful for servers which delay potentially unwanted clients when they perform commands other than AUTH.	2022-12-27 00:06:20 +11:00

Winni Neessen	48b4dc6b6c	Fix #85: Client.Send() failing for all messages if one is broken ... `Client.Send()` provides the possibility to send multiple `*Msg` in one go. If one of the `*Msg` caused an error with the sending mail server, we were returning completely, while not processing any `*Msg` that came after the failing message. This PR fixes this behaviour by processing each message first and then return a accumulated error in case any of the `*Msg` processing failed Additionally, this PR separates the `Client.Send()` method into two different versions. One that makes use of the new `errors.Join()` functionality that is introduced with Go 1.20 and one that handles it the old way for any supported version lower than Go 1.20	2022-12-10 13:41:00 +01:00

Winni Neessen	17b9d2ccf6	#80: GetAddrHeader and SetGenHeader ... This PR introduces two major changes: * SetHeader and SetHeaderPreformatted have been deprecated in favour of SetGenHeader and SetGenHeaderPreformatted As pointed out in #80 the naming was pretty confusing, given that we already have SetAddrHeader. With the new naming convention it should be more clear. For compatibility reasons the old methods have been kept for now but in reality they are just aliases to the new methods * GetAddrHeader and GetAddrHeaderString have been introduced As requested in #80 analogous to GetGenHeader we also need a similar method for the address headers. Since address headers are *mail.Address pointer, we've also added a *String method that will extract the address string and return a string slice instead Additionally we're introducing methods for the actual address headers: GetTo, GetFrom, GetCc and GetBcc (with a *String counterpart as well). This way the user has full flexibility. Either they use the more "low-level" GetAddrHeader method or the higher level methods for the corresponding address type	2022-11-19 11:22:20 +01:00

Winni Neessen	47eb7b582b	#81: Fix error handling in body writer ... The error handling in the msgWriter.writeBody() method was not working properly.

Winni Neessen	6f93e5835e	Introducing MiddlewareType and WriteToSkipMiddleware ... For middlewares to be able to access the fully written mail message, we need a way to execute WriteTo without the calling middleware to be handled, otherwise we end up in an infinite loop Therefore, this PR introduces the MiddlewareType and the corresponding change of the Middleware interface. We now require to return the MiddlewareType when the Type() method on the interface is called This way we can also introduce the WriteToSkipMiddleware method which takes a MiddlewareType as argument. This will allow us to use a WriteTo call with the initiating Middleware to be skipped	2022-10-25 16:42:18 +02:00
