1. go-smtp is replaced by a fork that reverts StartTLS removal.
2. SASL LOGIN is no longer supported by upstream go-sasl, readded disabled by default.
3. Updated endpoint code to match new go-smtp authentication interfaces.
4. certmagic repo had some renames
5. Minimum Go version increased to 1.23 to match dependencies.
1. Clarify that you need to manually create the user and group
when building from source. ./build.sh does not do that since
it is a packaging tool, not system configuration one.
2. Do not require "go" command to be present when running
./build.sh install. go installation may be user-specific and
unavailable when running with sudo.
3. Ease UMask restrictions. Allow group access.
This allows CLI commands to be run by any user in maddy group.
See #569.
Based on the spf documnet:
http://www.open-spf.org/action_browse_id_FAQ/Common_mistakes_revision_26/#helo
```
example.com. IN TXT "v=spf1 mx -all"
mailserver.example.com. IN TXT "v=spf1 a -all"
```
the second spf record in doc should set to a record.
otherwise the mail-tester will show
```SPF_HELO_SOFTFAIL SPF: HELO does not match SPF record (softfail)
```
softfail
Add more recommended best practice and fix a few mistakes.
1. SPF record should also be available via MX hostname (more precisely, HELO hostname we identify as)
2. MTA-STS requires an TXT record
3. TLSRPT can be used to get information about MTA-STS breakage.
4. Use p=quarantine in DMARC
5. Recommend deploying DANE in addition to MTA-STS
* Update setting-up.md
replacing hostname mx.example.org by example.org accordingly to the rest of the tutorial which doesn't refer to it (i.e. DNS configuration).
* readding MX1, with more detail
* adding A entry for mx1
* fixing ========
Now imapsql module does not handle authentication. (it was not doing it so well
anyway)
sql_table module was introduced and used in the default configuration as
a replacement for functionality that was implemented by imapsql before.
Parts of maddyctl code were rewritten to make it work transparently with
any IMAP backend or credentials store.
Closes#212.
Remove examples/ dir reference from REDME. It no longer exists.
Mention scdoc in installation tutorial.
Fix vim joke formatting.
Mention systemctl daemon-reload in intallation tutorial.
