Winni Neessen	93752280aa	Update smtp_test.go to add more authentication test cases ... Enhanced the LoginAuth test coverage by adding new scenarios with different sequences and invalid cases. This ensures more robust validation and better handling of edge cases in authentication testing.	2024-10-02 12:54:32 +02:00
Winni Neessen	071ad66035	Sync with upstream ... This PR syncs our smtp package with the upstream `net/smtp` changes introduced via bf91eb3a8b	2024-05-24 18:50:27 +02:00
Winni Neessen	07783d24e5	Update format string in Debugf method calls in tests ... The format string for the Debugf method calls within the smtp_test.go file have been updated. Previously, the format string was empty, but it has now been changed to "%s" to align with the standard formatting expectations, improving the correctness of the tests.	2024-04-06 17:13:45 +02:00
Winni Neessen	7a549242ae	Update Go version and clean up SMTP test suite ... The Go version has been updated to 1.22 in the .golangci.toml file for compatibility reasons. Additionally, unnecessary white space has been removed from the smtp/smtp_test.go file to maximize code efficiency and readability.	2024-02-08 16:51:25 +01:00
James Elliott	a73a914fb2	feat(smtp): auth login extension draft support ... This adds support for the auth login extension draft.	2024-01-07 13:34:33 +11:00
Winni Neessen	1c5c1e318c	#136: Refactor logging for clearer messaging direction ... The logging system in the smtp.go and log package has been refactored. A new custom log type `Log` was introduced, that includes the message direction, format and arguments. The `Logger` interface and the `Stdlog` implementation were modified to accept this new type. This change provides a clearer understanding of message direction inside logs, allowing for easier debugging and reduced complexity. This change does not affect features or disrupt user functionality. Additionally, it allows for custom implementations of the log.Logger interface to without being forced to use the C --> S/C <-- S direction logging.	2023-08-02 11:43:45 +02:00

Nicola Murino	6e4b348ccf	add Oauth2 support ... fixes #129	2023-05-28 14:31:04 +02:00
Winni Neessen	912797c782	#126: sync upstream changes to net/smtp ... Related: https://github.com/golang/go/issues/58141 Resolves #126	2023-04-12 09:54:26 +02:00
Winni Neessen	13d0add21c	#121: Remove defer from for loops ... Fixes #121. `defer` in for loops can possibly lead to leaks. The whole handling including the defer are now moved into anonymous functions outside the for loop and are called form the loop instead. This way the defer is handle when the inline function finishes	2023-03-15 18:42:25 +01:00
Winni Neessen	6633591b51	Implement Logger interface ... As stated in https://github.com/wneessen/go-mail/pull/102#issuecomment-1411956040 it would be beneficial if, instead of forcing the Go stdlib logger on the user to provide a simple interface and use that for logging purposes. This PR implements this simple log.Logger interface as well as a standard logger that satisfies this interface. If no custom logger is provided, the Stdlog will be used (which makes use of the Go stdlib again). Accordingly, a `Client.WithLogger` and `Client.SetLogger` have been implemented. Same applies for the smtp counterparts.	2023-02-03 10:19:26 +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	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	df7bb9b742	Fork net/smpt into go-mail ... Fix open TODO in smtp_test.go and fork `testenv.SkipFlaky()` from `internal/testenv` to implement flaky test skipping for FBSD	2023-01-11 20:07:03 +01:00
Winni Neessen	8e807c2569	Fork net/smpt into go-mail ... Fixed open issues in smtp_test.go	2023-01-11 15:28:33 +01:00
Winni Neessen	1836f6c49d	Start fixing golangci-lint findings in test suite	2023-01-10 16:55:47 +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
