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	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
