IMAP (RFC 3501): LOGIN through UID, previously all stubs except CAPABILITY/LOGOUT/a partial APPEND. Multi-folder support with per-folder UID/flag indexing (new MailFolder class, backed by .uidvalidity/.uidnext/ .imapindex sidecar files), ENVELOPE support (new MessageHeaders class: header parsing, address-list parsing, IMAP quoting), and shared cursor-based argument parsing (new IMAPArgs class: sequence sets, flag lists, dates, folder-name normalization, and path-traversal protection via isValidFolderName - a bare ".." folder name would otherwise resolve into a sibling user's mailbox directory). POP3 (RFC 1939): USER through QUIT, previously only CAPA. Added UIDL. POP3 handlers use cursor-based parsing throughout rather than indexed access - ZString's copy constructor doesn't copy its `list` field, and POP3's dispatch passes the request by value, so indexed access into a copy was silently reading nothing. SMTP: DMARC evaluation added to the DATA-terminator path (DKIM verification + alignment/policy, Authentication-Results header, conditional rejection matching RFC 7489 6.3's p=reject + sampled pct=). AUTH LOGIN now handles RFC 4954's optional inline initial response (e.g. Python smtplib's "AUTH LOGIN <base64>" in one line) instead of only the exact three-line form. Outbound relay now forces IPv4 (AF_INET) instead of AF_UNSPEC - this server's IPv4 has a correct PTR record and SPF coverage, its IPv6 doesn't, and Gmail was rejecting outbound mail with 550 5.7.25 as a result. Delivery pipeline: local delivery now runs the message through SpamAssassin (new SpamAssassinFilter class, speaking spamd's PROCESS protocol directly over a raw socket - fails open/delivers unscanned if spamd is unreachable) instead of a plain hardlink, since scanning can tag/modify content. BARANTMailConfig: extracted config loading into its own class. compile: (see individual file changes - build script adjustments to match the above). Deliberately excluded from this commit: barantmail.log/ barantmail-service.log (operational logs, not source - barantmail.log in particular was the runaway 55GB/12.9GB file from a busy-loop bug fixed separately in ServerCore) and barantmail.cfg (this server's own live deployment config, matching how APIServer's equivalent config also stays untracked).
