Problems with eMail / Dovecot


after the last routinely update on Dec. 14th to the
System version NethServer release 7.6.1810 (final)
Kernel 3.10.0-862.14.4.el7.x86_64

SOGo can no longer access the mailboxes of the user, as well as the reception and sending of mail is no longer possible.

Is there a solution to the problem?



That would be the approach I have …
Here would be an excerpt from the mail log:

> Dec 15 09:11:22 openzwo dovecot: lmtp(7652): Connect from local Dec 15 09:11:22 openzwo dovecot: lmtp(7652, Fatal: Plugin 'sieve_imapsieve' not found from directory /usr/lib64/dovecot/sieve Dec 15 09:11:23 openzwo postfix/lmtp[7651]: 8F1B253C: to=<>,[/var/run/dovecot/lmtp], delay=522, delays=522/0.06/0.08/0.12, dsn=4.4.2, status=deferred (lost connection with[/var/run/dovecot/lmtp] while sending end of data -- message may be sent more than once)

It seems that dovecot-pigeonhole is missing.
You could try to install it with yum dovecot-pigeonhole.

Here’s what I have:

[root@nethservice ~]# rpm -q dovecot-pigeonhole

I also have the same version:

[root@openzwo ~]# rpm -q dovecot-pigeonhole
[root@openzwo ~]#

I wanted to reinstall but then I get the following error message that it is not found.

[root@openzwo ~]# yum reinstall dovecot-pigeonhole*

To address this issue please refer to the below wiki article

If above article doesn't help to resolve this issue please use

maybe cleaning up the yum cache can help?

You may run:
yum clean all && yum makecache

and after this try do a full update:

yum update


Hi, Thank You @mark_nl !

That was the problem.
Only why the installation routine always gets stuck, that was the problem for the second time.
