Hi guys. I'm freaking out with this, please help me. I just created a new accound from iRedAdmin* and then signed in through SOGo. Then I went to the settings, IMAP, identity... added a signature, accepted the changes, then I clicked on the round Save button and an error popped out.

(*): a couple of minutes before I added the organization name to that domain, that I noticed it was blank.

Now I see this:

And if I logout, I can't login again from other accounts (and I use this for work!)

In the logs I just see trillions of:

Jul 08 09:44:03 sogod [15407]: <0x0x55fa68a42850[NGSieveClient]> WARNING: got exception try to restore connection: <NGStreamWriteErrorException: 0x55fa68bb8d50> $
2020-07-08 09:44:03.022 sogod[15407:15407] ERROR(-[NGActiveSSLSocket startTLS]): couldn't setup SSL connection on host 127.0.0.1 (error:00000001:lib(0):func(0):r$
Jul 08 09:44:03 sogod [15407]: <0x0x55fa68a42850[NGSieveClient]> Could not start TLS.

I see something about TLS, should I restart it? (how?)
And most of all... how is it possible that for changing a signature everything breaks apart?

And every day I see a couple of notifications in my email about automatic backups. Does it mean that I could just reinstall everything and restore everything as it was yesterday? (I'll start making rsync backups every single day)

Thanks!!!

Did you change any config files before this issue occurred?
Or, did you just upgrade SOGo packages?

It's backup of SQL databases, it does NOT backup mailboxes.

I have this error:

Upgrading web.py doesn't help.
Centos 7 system with Iredadmin pro

Ok, this is horrible.

Now, after some minutes, for some reason I can access to my account, but it looks empty. No folders at all:

Aaaaand now I was trying to do more things to look for more symptoms, but the server just went down (what is happening?)

Nothing. Just that.

Well, before creating that new account, I added the company name in the domain options. And that's it.

Ok, wait. Could I restore the database to how it was yesterday then? Maybe that could fix the problem. Where could I find a guide on how to do that? Is a plain db restore from MariaDB?

Update

In the SOGo log file I found tens of thousands repeats of this line now:

Jul 08 10:10:27 sogod [15407]: [ERROR] <0x0x55fa693b0530[_WOStringTable]> could not read strings file: /usr/lib/GNUstep/SOGo/PreferencesUI.SOGo/Resources/Spanish$

Was wondering how to change the first mail domain name.

So, in order to host the mails of my e-mail account provided by my ISP (myfirstname.mylastname@isp.com), I created in iredadmin a second user under my domain: isp.mail@mydomain.eu . Mails are retrieved from my ISP’s POP3 server via Getmail, following this how-to posted in the forum.

My last missing piece of the puzzle is how to send mails as ‘myfirstname.mylastname@isp.com’ via my ISP smtp server. In contrast to my other account ‘myfirstname.mylastname@mydomain.eu’, where I want that messages are sent as ‘myfirstname.mylastname@mydomain.eu’ in the FROM field, the mails sent under the user account isp.mail@mydomain.eu should be sent as ‘myfirstname.mylastname@isp.com’.

As far as I understand, there are 2 possibilities:

1) I put ‘myfirstname.mylastname@isp.com’ as the e-mail address in the e-mail client. I'm not sure whether the security settings in iRedMail allow for ‘impersonating’ another e-mail address?

2) I use the postfix address rewriting function with ‘smtp_generic_maps’. According to the postfix documentation, the address rewriting does not take place when sending mails internally, i.e. from isp.mail@mydomain.eu to myfirstname.mylastname@mydomain.eu.

What would be the way to go?

Hi Everyone.

My VPS (1 vcpu/2GB RAM) is triggering high memory usage (100%) errors for me about once or twice a day.

It's a low load mail server. I don't mind occasionally going in there restarting some services if that's what it takes.

My htop and netdata is attached.

How do I restart the process taking up the most memory: clamd

I've tried:

service clamd status
service clamd.d status
service clamav status
service clamavd status

They all say that the service doesn't exist.

Hello,

I am evaluating iredmail and trying to do some test with one account for a while before migrating all my accounts to iredmail.

My iredmail server only has one email account and will be using other server on the internet as relay host. The problem is that i need the local server with the same domain name as the remote(relay server). When i send an email to other email account the iredmail validate it an returned error 550 because the recipient account doesn't exist on local server but it does in the remote (relay server).

It is possible to force to relay and send the email to the relay serve even the recipient account doesn't exist locally? In other words, is it possible to disable local verification of the recipient email account before send?

Regards,
Carlos

Ok, I think I finally isolated the problem.

I did a fresh install of iRedMail with SOGo in a different VPS and the problem appeared again (maybe a bug?)
I followed this guide: https://www.linuxbabe.com/mail-server/d … ail-server

Then I created some domains and users in iRedAdmin

After that, I logged in via SOGo

I can see my inbox fine. But if I click the settings button (the cog icon) that "missing component" of my firsts screenshots appears.

And I found something in sogo.log that repeats every time I replicate the problem:

It starts with these lines:

I see a lot of different things there, and I'm not an expert so I don't know how to interpret them. It seems to me that many different things are failing, like TLS, something abut MySQL, locales... so I'd guess that there's some one particular problem that provoked all of that.

Weird thing is that this is a fresh install. And I followed the same guide I used weeks ago and that worked fine until this error appeared.

Should I report this as a bug? Because I've been searching for this in Google all day and seems that nobody else has this problem.

Any help would be greatly appreciated, seriously.

What may be happening...????

I had the same/similar problem a couple of days ago after upgrading SOGo from the nightly repositories. In my case it was apparently caused by a recent change so that SOGo now actually does hostname validation for TLS connections (see https://github.com/inverse-inc/sope/pull/52 and https://github.com/inverse-inc/sope/pull/56).

After some experimentation (I am no expert in any of this), I found the cause in my case was the configuration for the sieve scripts. So if you have those enabled (see https://docs.iredmail.org/why.no.sieve. … sogo.html) this might help: In /etc/sogo/sogo.conf I changed the line

SOGoSieveServer = "sieve://127.0.0.1:4190/?tls=YES";

to

SOGoSieveServer = "sieve://127.0.0.1:4190/?tls=NO";

And that was it. You don't mention if you have sieve scripts enabled (I understand in a standard installation, if roundcubemail is also installed, this would be disabled), but if you have you can give it a try and maybe it helps.

==== REQUIRED BASIC INFO OF YOUR IREDMAIL SERVER ====
- iRedMail version (check /etc/iredmail-release):
- Deployed with iRedMail Easy or the downloadable installer?
- Linux/BSD distribution name and version:
- Store mail accounts in which backend (LDAP/MySQL/PGSQL):
- Web server (Apache or Nginx):
- Manage mail accounts with iRedAdmin-Pro?
- [IMPORTANT] Related original log or error message is required if you're experiencing an issue.
====

I have experienced many users connect pop3 with outlook, they always get popup  windows for enter username and password, they just click OK button then it can send/receive mail normally.
And sometimes you have to click more than once and now it is not sending email stuck in outbox.
I have valid SSL Certificate 

Please assist

The document is correct.
Please turn on debug mode in Dovecot to figure out why it doesn't work as you expected:
https://docs.iredmail.org/debug.dovecot.html

The dependent Python module "requests" relies on another module named "certs".

On CentOS 7, you can install "requests" module with command below, it should install all required packages at the same time.

yum install python-requests

SOGo nightly build is not always stable.
