Winni Neessen	263f6bb3de	Refactor SMTP client code for better readability ... The variable names in the code related to the I/O of the SMTP client have been clarified for improved readability and comprehension. For example, unclear variable names like `d` and `w` have been replaced with more meaningful names like `depth` and `writer`. The same naming improvements have also been applied to function parameters. This update aims to enhance code maintenance and simplify future development processes.	2024-02-24 12:43:01 +01:00
Winni Neessen	ef86a1a1fb	Add Charset support for message parts ... Charset support has been added in the 'Part' struct. A 'SetCharset' method and a 'WithPartCharset' option have been added to override the default Part charset. The 'writePart' function in msgWriter now accommodates the charset defined at the Part level, defaulting to the previous functionality if not set.	2024-01-31 16:28:41 +01:00
Winni Neessen	b63d4803f1	Refactored null checks in msgwriter.go ... Extended null check conditions in msgwriter.go to prevent potential nil pointer dereference. This change ensures robustness in error handling in scenarios where FROM header or envelope FROM is either not existent or nil.	2023-11-29 16:56:32 +01:00
Winni Neessen	edd6051df3	#138: Add error handling to message writing process ... In the updated version of msgwriter.go, an additional error handling process has been included. If an error is detected when creating a new part in the message writer, this error is stored and prevents executing the writeBody function. This fixes nil pointer dereference in `mw.writeBody` if an error occured previously.	2023-08-08 10:59:10 +02:00
Winni Neessen	fe28247f9b	The additional multipart start/stop are not needed here	2023-01-31 21:54:32 +01:00
Winni Neessen	dab860834a	Adding PGPType to Msg as preparation to support PGP/MIME in go-mail-middleware	2023-01-31 18:35:48 +01:00
Winni Neessen	9724a2b523	Introducing Msg part deletion ... This PR introduces a new struct field for the message parts: `del` If the del flag is set to `true`, the msgWriter will ignore this part during the writing process. Additionally, the `part` has now a `Delete` method that lets the user mark the part as deleted This allows middleware to take further control of the Msg and is part of #107	2023-01-28 14:39:14 +01:00
Winni Neessen	3922d3f195	Switched copyright header from me to "The go-mail Authors"	2023-01-15 16:14:19 +01:00
Winni Neessen	47eb7b582b	#81: Fix error handling in body writer ... The error handling in the msgWriter.writeBody() method was not working properly. We basically overwrote the mw.err with nil if the function that followed after a failed write attempt was successful again This patch fixes #81	2022-11-19 09:55:38 +01:00
Winni Neessen	2e60d070a6	Add SetHeaderPreformatted() method ... With the SetHeaderPreformatted() method we have the ability to set headers that are already preformatted by the user and will not be altered in the mail message output	2022-10-26 15:33:03 +02:00
Winni Neessen	701cbbf399	Fixes a bug with attachments. Hopefully addresses #37 as well ... By default, the encoding/base64 in Go does not add line breaks to its output. This patch introduces the Base64LineBreaker which satisfies the io.WriteCloser interface Attachments are now correctly broken up into maximum of 76 chars	2022-08-14 12:06:26 +02:00
