Winni Neessen	277ae9be19	Refactor message sending logic ... Consolidated the message sending logic into a single `sendSingleMsg` function to reduce duplication and improve code maintainability. This change simplifies the `Send` method in multiple Go version files by removing redundant code and calling the new helper function instead.	2024-09-19 10:56:01 +02:00
Norbert Hauriel	c811ee689f	fix(typo): client.go error message	2024-07-24 13:12:06 +02:00
Winni Neessen	94138b6d23	Refine SMTP port selection and fallback logic ... The update modifies the client's handling of port selection when configuring SSL/TLS connections. The clients' functions `WithSSLPort`, `WithTLSPortPolicy`, `SetTLSPortPolicy`, and `SetSSLPort` are revised to avoid overriding previously set ports. Additionally, the deprecation notes have been removed and replaced with notes on best-practice recommendations, referring the new *Port*() methods. This change revises #105 and takes the comments made in #181 into account.	2024-04-06 16:49:34 +02:00
Winni Neessen	f18335fa1d	Refactor variable names in SMTP client code ... Improved variable names in the SMTP client code to make them more expressive and descriptive. Also corrected several code comments to enhance clarity. These changes are intended to increase code readability and maintainability and have been implemented throughout the client_119.go and client.go files for consistency in naming conventions.	2024-02-25 17:48:53 +01:00
Winni Neessen	e1098091c3	Refactor variable names in SMTP client code ... The commit introduces improved variable names in the SMTP client code that are more expressive and better describe the function they perform. This is combined with corrections to some code comments. It's aimed to increase code readability and maintainability. Updates are made across the client_119.go and client.go files to ensure consistent naming conventions.	2024-02-24 22:06:18 +01:00
Winni Neessen	1efac7fb67	Add new test cases for client functionalities and clean client code ... Test cases have been added for numerous client functionalities including WithTLSPortPolicy option for the NewClient method, Client.SetSSLPort method, and the Client.DialWithContext method with the fallback port functionality. Minor code simplification has also been performed in the 'SetSSLPort' function in client.go file.	2024-01-31 11:22:01 +01:00
Winni Neessen	7a2d9ff938	#105: Add default ports and fallback behavior for SSL and TLS ... Introduced default ports for SSL/TLS and STARTTLS connections in SMTP client. Also added fallback behavior, allowing the client to attempt connections on port 25 using plaintext if secured connections fail. Deprecated old methods and implemented new ones to enforce these changes effectively. This is a copy of the PR muhlemmer:enhance-default-tls-port by @muhlemmer. Since they unfortunately didn't reply in the PR anymore I cloned the PR. They will be fully attributed in the PR, though.	2024-01-25 13:39:02 +01:00
Winni Neessen	bb18ef9e93	"Improve error checking in SMTP client creation" ... A change was made in the SMTP client creation process to add more robust error handling. The new logic checks if the client is null after being created and, if true, returns an error. This update can help prevent potential null pointer exceptions in runtime, ultimately leading to more stable application.	2023-11-29 16:25:35 +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	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	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
Winni Neessen	f454ae8c41	Merge pull request #88 from james-d-elliott/feat-without-noop ... feat: without noop option	2022-12-26 16:49:38 +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
James Elliott	b8646489ae	fix: tls config unused with dialer ... This ensures the configured tls.Config is used with the tls.Dialer.	2022-12-26 23:48:52 +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
