The account switcher dropdown previously showed the IMAP username
(typically the email address) for the primary account. Now it falls
back to the identity's display name when available, matching the
behavior of secondary accounts which use their custom label.
Priority order: global_alias session var > primary identity display
name > IMAP username.
SMTP and Sieve hooks follow parent_id to resolve alias config from parent
account. Aliases excluded from account switcher dropdown and background
mail checker. Debug logging behind ident_switch.debug config flag.
Fix double ssl:// prefix in switch_account host parsing.
Identities can now be set as primary (default), alias of an existing
separate account, or separate account. Alias records store parent_id
and skip server validation. Password sentinel changed to a safe string
that survives HTML form round-trips. Preconfig host composition fixed
to include security scheme.
Major form improvements:
- Custom SMTP/Sieve credentials (separate username/password per protocol)
- Connection testing on save (IMAP, SMTP, Sieve) with localized errors
- preconfig_only mode to restrict domains to preconfigured entries
- Form POST value preservation on save errors (auth selects, passwords)
- Smart host placeholders (SMTP/Sieve default to IMAP host)
Security and bug:
- Fix password re-encryption bug (was comparing raw vs encrypted values)
- Fix XSS: escape label output in special folders form
- Fix parse_url() return value not checked for false
- Fix decrypt() failures not handled (fallback to empty string)
- Sanitize log output (remove raw POST data from log messages)
- Replace weak == comparisons with strict === (PHP and JS)
SQL changes:
- Consolidate 4 migrations (2026021000-03) into single 2026021000
- Remove now unused notify_sound_url column
- Add smtp_username, smtp_password, sieve_username, sieve_password columns
Replace the single IMAP TLS checkbox with a per-protocol security
dropdown for IMAP, SMTP, and Sieve. The security scheme (ssl:// or
tls://) is now stored directly in the host field, unifying the approach
across all protocols.
Smart form behavior:
- Default ports update automatically when changing security type
- Fields clear on blur when value matches the placeholder
- Warning shown when selecting no encryption
- Defaults: IMAP SSL/993, SMTP STARTTLS/587, Sieve STARTTLS/4190
The DB_SECURE_IMAP_TLS flag is no longer written but still read for
backward compatibility with existing records.
Roundcube auto-detects the delimiter from the IMAP server via LIST
command. Remove hardcoded fallback values and let Roundcube handle
detection when no delimiter is explicitly configured.
When switching identities, the managesieve plugin still connected to
the default sieve server. Hook into managesieve_connect to redirect
the sieve connection to the remote account's server.
Adds sieve_host, sieve_port and sieve_auth columns to the database,
a Sieve section to the identity settings form, preconfig support for
sieve_host, and localized labels for all 7 languages.
The preconfig previously used a single 'host' field for both IMAP and
SMTP, making it impossible to configure different servers/schemes/ports
(e.g. IMAPS on 993 + SMTP STARTTLS on 587). Also, ssl:// scheme was
silently lost during parse_url() since only tls:// was recognized.
Add imap_host and smtp_host as separate config keys with full scheme
support (ssl://, tls://). The legacy 'host' key is still supported as
fallback for backward compatibility.
Extract business logic into dedicated classes under lib/:
- IdentSwitchForm: form building, validation, and persistence
- IdentSwitchSwitcher: account switching, SMTP config, special folders
- IdentSwitchPreconfig: domain-based preconfiguration
The main plugin class remains the orchestrator, registering hooks
and delegating to the appropriate handler. Constants changed from
private to public to allow cross-class access.
