Getting Dovecot On Ubuntu server & Working With TBird & RoundCube

[Dan Kierson]

I have been having a problem with getting dovecot to work with Thunderbird email client & RoundCube web mail client.

Is there any such thing as a Ubuntu/Linux consultant in the Limerick/Midwest region ?

[Ray O'Donnell]

No idea about consultants, but I have that set-up working on Debian....
feel free to email me off-list and I'll help if I can.

Ray.

Hi Ray & Tina,

Just got the damn thing working via these Linuxbabe procedures for Post-Dovecot mail servers:

Part 1  https://www.linuxbabe.com/mail-server/setup-basic-postfix-mail-sever-ubuntu

Part 2  https://www.linuxbabe.com/mail-server/secure-email-server-ubuntu-postfix-dovecot

Part 3  https://www.linuxbabe.com/mail-server/postfixadmin-ubuntu

Part 3A  https://www.linuxbabe.com/mail-server/host-multiple-mail-domains-in-postfixadmin

Part 4  https://www.linuxbabe.com/mail-server/setting-up-dkim-and-spf

Part 5  https://www.linuxbabe.com/mail-server/create-dmarc-record

Part 5A  https://www.linuxbabe.com/mail-server/how-to-stop-your-emails-being-marked-as-spam

Roundcube   https://www.linuxbabe.com/ubuntu/install-roundcube-webmail-ubuntu-20-04-apache-nginx#out-of-office

I'm after doing Parts I and 2. I'm passing emails via Thunderbird to an OVH mail host on to my VPS "mailserver"

and back down to Thunderbird. Reverse path too.

But this is just for a mail account associated with a given Ubuntu server user account.

Next Part 3 is about setting up virtual mailboxes and that will have plenty for me to fall over.

At least I have the filters working so parts 4 & 5 need only be skimmed.

Thanking you for your support offers which I really appreciate.

DK.

Hi Dan,

Sorry for the slow reply.... Glad you got it working. Email isn't easy
to get right, and all too easy to get wrong!

A useful tool, in case you haven't heard of it, is swaks ("Swiss Army
knife for SMTP"):

https://www.jetmore.org/john/code/swaks

I think most Linux distributions have it in their repositories. It lets
you see exactly what's going on in the SMTP conversation - really handy
for debugging.

Best of luck with the virtual-domain setup.... This is what I run, and
if I can help I'll be glad to.

Best,

Ray.

I am stuck on a login page to the PostfixAdmin interface.

The setup password and superadmin account have been entered. 

But when I go to the https://postfixadmin.mysite.com.login.php page and enter the superadmin name and password, all I get is the message:

Your email address or password is not correct. See screenshot below . . . 

This phrase is associated with a pLogin_error when I search for the string among the PostfixAdmin files.

I have done it and redone it over and over again. I tried versions 3.3.11 and 3.3.13 of PostfixAdmin but it's always the same.

I am wondering about the creation of a superadmin account. In the "Setup password" field I put the plain password, not its 

generated hash. Is this okay ? Also I followed the instructions and applied an email address on the mail domain even though 

virtual users hadn't yet been set up in PostfixAdmin. Is this okay ?

Above login.php problem solved.

The cause was the "warning" about an obsolete setting in /etc/dovecot/conf.d/10-ssl.conf which had 

 . . . .

. . . . 

# Dovecot also recognizes values ANY and LATEST. ANY matches with any protocol
# version, and LATEST matches with the latest version supported by library.
ssl_min_protocol = TLSv1.2
ssl_protocols = !SSLv3 !TLSv1 !TLSv1.1
. . . . 
. . . . 

Apparently the ssl_min_protocols setting makes obsolete the ssl_protocols one so it had to be commented out.

Far more than a warning really - it's a show-stopping ERROR !

For now,

DK
