Winni Neessen	63d8cef8ca	Refactor DSN handling from client.go to smtp.go ... This PR refactors the the DSN (RFC 1891) SMTP client handling, that was introduced in f4cdc61dd0. While most of the Client options stay the same, the whole workaround logic for the SMTP client has been removed and added as part of the SMTP client instead. This was we got rid of the Client's own `mail()`, `rcpt()`, `dsnRcpt()`, `dsnMail()` methods as well as the copies of the `cmd()` and `validateLine()` methods. The Client is now using the proper `Mail()` and `Rcpt()` methods of the SMTP client instead.	2023-01-18 10:30:06 +01:00

Winni Neessen	e36511e90e	Fix tests to not log authentication data ... We don't want to expose SMTP authentication details in tests, therefore the tests have been adjusted a bit	2023-01-14 13:05:04 +01:00
Winni Neessen	34b432a985	Implement debug logging in SMTP client ... Resolves #101. Since we now have full control over the SMTP client we can also access the message input and output. This PR introduces a new debug logging feature. Via the `Client.WithDebugLog` the user can enable this feature. It will then make use of the new `smtp/Client.SetDebugLog` method. Once the flag is set to true, the SMTP client will start logging incoming and outgoing messages to os.Stderr. Log directions will be output accordingly	2023-01-14 12:47:51 +01:00
Winni Neessen	8559e8c301	Re-introduce backwards compatibility with Go 1.17 and Go 1.18 ... The following changes make use of methods that are not available in Go 1.17/Go 1.18. To guarantee at least 4 versions of backwards compatibility, versioned copies of those changes have been back-ported: - 4d8db00641 (diff-4f6f6bdb9891d4dd271f9f31430420a2e44018fe4ee539576faf458bebb3cee4) - 58158e990f (diff-772fc9f5d0c86f26e35158fb3e7a71a4967d18b4ec23a5dbb60781ab0babf426)	2023-01-13 17:34:41 +01:00
Winni Neessen	7cb34856a3	Adjusting license headers and including original LICENSE file from the Go project into the smtp/ directory as suggested in https://github.com/wneessen/go-mail/issues/97#issuecomment-1381046444	2023-01-13 16:54:55 +01:00
Winni Neessen	a804e4a101	Fix license SPDX headers for forked net/smtp code ... - Also import the original BSD-3-Clause.txt license from the Go team into the LICENSES directory - Further on, license headers should hold "The go-mail Authors" instead of my name. Did this already for the MIT license.	2023-01-10 10:09:45 +01:00
Winni Neessen	0d6777ab39	Fork net/smpt into go-mail ... As part of #97 we are going to fork the official `net/smtp` package into go-mail to provide us with more flexibility. This commit fulfills the first big step of importing the package into smtp/. Also go-mail's own LoginAuth has been moved from auth/ into smtp/ to be consistent with the stdlib. There are still a couple of open issues (i. e. license adjustments and making golangci-lint happy) but so far all tests already work, which is a good start.	2023-01-10 00:38:42 +01:00
