Welcome to go-mail v0.6.2! This release fixes some bugs and makes go-mail ready for Go 1.24.
Fix regression of custom SMTP authentication handling
PR #429 fixes a regression in the handling of custom smtp.Auth methods that was introduced with the v0.6.0 release. Basically, if a custom SMTP auth method was provided, it was simply ignored. Thanks to @james-d-elliott of the Authelia project for reporting this.
Fix possible nil pointer derefernece in SendWithSMTPClient
With commit 4641da4 we fixed a possible nil pointer dereference in the SendWithSMTPClient method. This would happen if a nil message would be provided to the method. This bug was reported using Github's private vulnerability reporting feature by @younes199511. Thanks for the report!
Header count logic improvements
PR #421 fixed an issue in the header count logic that is used for S/MIME signing. If a header was broken into mutliple lines due to its lenght, the count logic was giving false results, resulting into false content for the S/MIME signature. Thanks to @theexiile1305 for reporting the issue and helping to debug the issue!
