MailKit 3.5.0 (2023-01-27)

• Fixed SMTP client logic to calculate the needed bytes before converting commands into into the output buffer. (issue #1498)

MailKit 3.4.3 (2022-11-25)

• Modified SmtpClient to only send the ORCPT argument to RCPT TO if NOTIFY is specified.
• Improved performance of Pop3Client by reducing memory allocations.
• Refactored sync and async Pop3Client APIs such that the synchronous APIs no longer call methods marked with async in order to reduce AsyncMethodBuilder state machines/allocations.
• Improved IMAP's BODY/BODYSTRUCTURE parser to be able to scan ahead multiple tokens in order to better handle syntactically incorrect responses in a more graceful way. (issue #1446)
• Improved IMAP's ENVELOPE parser to handle ("Microsoft Exchange Server" NIL NIL ".MISSING-HOST-NAME.") in a more graceful way. (issue #1451)
