MailKit 3.2.0

MailKit is an Open Source cross-platform .NET mail-client library that is based on MimeKit and optimized for mobile devices. Features include: * HTTP, Socks4, Socks4a and Socks5 proxy support. * SASL Authentication via ANONYMOUS, CRAM-MD5, DIGEST-MD5, LOGIN, NTLM, OAUTHBEARER, PLAIN, SCRAM-SHA-1, SCRAM-SHA-256, SCRAM-SHA-512 and XOAUTH2. * A fully-cancellable SmtpClient with support for STARTTLS, 8BITMIME, BINARYMIME, ENHANCEDSTATUSCODES, SIZE, DSN, PIPELINING and SMTPUTF8. * A fully-cancellable Pop3Client with support for STLS, UIDL, APOP, PIPELINING, UTF8, and LANG. * A fully-cancellable ImapClient with support for ACL, QUOTA, LITERAL+, IDLE, NAMESPACE, ID, CHILDREN, LOGINDISABLED, STARTTLS, MULTIAPPEND, UNSELECT, UIDPLUS, CONDSTORE, ESEARCH, SASL-IR, COMPRESS, WITHIN, ENABLE, QRESYNC, SORT, THREAD, ANNOTATE, LIST-EXTENDED, ESORT, METADATA / METADATA-SERVER, NOTIFY, FILTERS, LIST-STATUS, SORT=DISPLAY, SPECIAL-USE / CREATE-SPECIAL-USE, SEARCH=FUZZY, MOVE, UTF8=ACCEPT / UTF8=ONLY, LITERAL-, APPENDLIMIT, STATUS=SIZE, OBJECTID, REPLACE, SAVEDATE, XLIST, and X-GM-EXT1. * Client-side sorting and threading of messages (the Ordinal Subject and the Jamie Zawinski threading algorithms are supported). * Asynchronous versions of all methods that hit the network. * S/MIME, OpenPGP, DKIM and ARC support via MimeKit. * Microsoft TNEF support via MimeKit.

No packages depend on MailKit.

* Do not use ApplicationProtocols with SSL. (issue #1352) * Updated GMail, Yahoo, and Outlook.com certificates. * Lazy-initialize MessageSummary.Keywords. This reduces memory usage when the client isn't requesting Flags/Keywords. * Hard-cache some IMAP FETCH-related tokens in order to relieve GC pressure for commands like FETCH where there can be a LOT of responses containing the same tokens over and over again. * Converted some IMAP async Task methods to use ValueTask to reduce GC pressure. * Reduced string allocations in the IMAP logic by avoiding use of ToUpperInvariant(). * Added non-async implementations for ImapStream APIs to be used by the synchronous public APIs to avoid some async overhead. * Reduce MemoryStream (and thus byte[]) allocations by using a new ByteArrayBuilder. * Rewrote the IMAP CAPABILITY parser to avoid allocating strings. * Fixed some cases where IMAP NIL tokens were not compared case insensitively. * Always include the VERSION block in NTLM messages. (issue #1340) * Target .NET Framework v4.6.1 instead of v4.6 to match the changes in MimeKit. * Capture the Socket timeout value in Read/WriteAsync() to have it in case of exceptions. (issue #1327)
