Description

This contribs will deploy Microsoft Autodiscover and Mozilla autoconfig to configure your IMAP POP and SMTP accoutn to your mails clients. Plan is to also support creation of apple configuration file in the future.


Installation

prerequisite you need a valid SSL certificate, redirection might fails if https uses a non valid certificate, try Letsencrypt <tabs container> <tab name="For SME 11"> 

dnf install {{#var:smecontribname}}

</tab> <tab name="For SME 10"> 

yum --enablerepo=smecontribs install {{#var:smecontribname}}

</tab> </tabs>

Configuration

Client Side

Mozilla compatible products

Thunderbird, Evolution and any software compatible with the Mozilla Thunderbird .well-known/autoconfig/mail/config-v1.1.xml config file will work by just filling your email and password.

Outlook before 2016

Will also work out of the box by just filling your email and password.


Outlook 2016

Out of the box, it does not support IMAP POP3 and SMTP autodiscover, but only exchange type server. There are two methods you can use to workaround that. First is using the old style outlook profile configurator 

C:\Program Files (x86)\Microsoft Office\root\Office16\OLCFG.EXE

then button email accounts or 

C:\Program Files\Microsoft Office\root\Office16\OLCFG.EXE

then button email accounts

Second would be to force Outlook to use old detection configuration by manipulating Registry, as a priviledged user run in a windows shell: 

reg add "HKEY_CURRENT_USER\SOFTWARE\Policies\Microsoft\Office\16.0\Outlook\setup /T REG_DWORD /F /V DisableOffice365SimplifiedAccountCreation /D 1"
Outlook 2019

Out of the box, it does not support IMAP POP3 and SMTP autodiscover, but only exchange type server. You will need to enable old Outlook 2016 accounts. see : https://wiki.contribs.org/Email#Outlook_365_.2F_Outlook_2019_IMAP_Configuration

alternatively the Outlook 2016 should work 

C:\Program Files (x86)\Microsoft Office\root\Office19\OLCFG.EXE

then button email accounts or 

C:\Program Files\Microsoft Office\root\Office19\OLCFG.EXE

then button email accounts

Second would be to force Outlook to use old detection configuration by manipulating Registry, as a priviledged user run in a windows shell: 

reg add HKEY_CURRENT_USER\SOFTWARE\Policies\Microsoft\Office\19.0\Outlook\setup /T REG_DWORD /F /V DisableOffice365SimplifiedAccountCreation /D 1"
Outlook 365

Need testing,, does not support IMAP POP3 and SMTP autodiscover. Only exchange type server.

Outlook for Android

Need testing, but mostly work as Outlook 365.

Template:Note box caldav with or without TLS , could use a TXT field too, if no txt value is present then client will check /.well-known/caldav 

_caldav._tcp     SRV 0 1 80 calendar.example.com.
_caldavs._tcp    SRV 0 1 443 calendar.example.com.
_caldav._tcp    TXT path=/caldav

cardav , could use a TXT field too, if no txt value is present then client will check /.well-known/cardav 

_cardav._tcp     SRV 0 1 80 calendar.example.com.
_cardavs._tcp    SRV 0 1 443 calendar.example.com.
_cardav._tcp    TXT path=/caldav
_cardavs._tcp   TXT path=/caldav

DNS and file for MTA-STS and TLS-RPT

as you are there you can inform the worl you use along side with DKIM, SPF and DMARC properly configured this. See

create a subdomain mta-sts.yourdomain.com , make it point to your server, and set Let's Encrypt to create a certificate for it

fill the content of the file /home/e-smith/files/ibays/Primary/.well-known/mta-sts.txt with<syntaxhighlight lang="console"> version: STSv1 mode: testing mx: yourdomain.com max_age: 604800 </syntaxhighlight>fill the following records at your dns. (fill the id field with current timestamp, and update the domain/ email to your needs)<syntaxhighlight lang="console"> _smtp._tls.yourdomain.com. 900 IN TXT "v=TLSRPTv1; rua=mailto:admin@yourdomain.com" _mta-sts.yourdomain.com. 900 IN TXT "v=STSv1; id=1575556993" </syntaxhighlight>

DNS and BIMI Record

add a picture as svg accessible with your web srver, be sure DMARC fields are ok. and then file the DNS field, with the correct URL. You might need to check if your SVG is compatible <syntaxhighlight lang="console"> default._bimi IN TXT "v=BIMI1; l=https://yourdomain.com/images/Logo.svg" </syntaxhighlight>you might also obtain a certificate for your logo after having validate your ownership see: Verified Mark Certificates (VMC). As of 2023 this is a paid certificate for about 1500 USD a year, after registering for your trademark. So this will be kept out of scope of this page for the moment

DNS DKIM /SPF and DMARC

see Email#DKIM Setup - qpsmtpd version .3E.3D 0.96

DNS CNAME Record

having a CNAME for autodiscover pointing to your server could help but is not mandatory.
