I'm trying to set up my dovecot server to access curl request over LAN by following https://doc.dovecot.org/2.3/admin_manual/doveadm_http_api/#admin-doveadm-http-api

My OS is: Rocky 9 linux and dovecot version is:2.3.16

in /etc/dovecot/conf.d/ my mail-location set as:

mail_location = maildir:/home/vmail/%d/%n/Maildir

and

inbox = yes

/etc/dovecot/dovecot.conf, I added

doveadm_password = admpass
service doveadm {
     unix_listener doveadm-server {
             user = vmail
     }
     inet_listener {
             port = 2425
     }
     inet_listener http {
             port = 8080
             #ssl = yes # uncomment to enable https
     }
}

when I run

doveadm fetch -u [email protected] "text" MAILBOX INBOX UNSEEN

I can grab the new emails properly.

But when I try to fetch emails by using curl.

curl -u doveadm:admpass -X POST -H "Content-Type: application/json" -d '[[ "fetch", { "mailbox": "INBOX", "user": "[email protected]"}, "tag1" ]]' http://localhost:8080/doveadm/v1

I get this error:

[["error",{"type":"invalidRequest", "exitCode":0},"tag1"]]

How I can query my user's new emails by using curl from LAN host? And get the response in json format?

I'm trying install Gammu 1.42 to serve my SMS gateway on Centos 8.

make, make test, make install works fine.

LD_LIBRARY_PATH configured in /etc/profile as:

......
LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/lib:.:/usr/local/lib64
export PATH USER LOGNAME MAIL HOSTNAME HISTSIZE HISTCONTROL LD_LIBRARY_PATH
......

I print env by printenv, LD_LIBRARY_PATH found. /etc/gammu-smsdrc configured as:

......
[gammu]
device = /dev/ttyUSB0
model = E3131
connection = at115200

[smsd]
service = sql
driver = native_pgsql
logFIle = /var/log/gammu/smsd.log
logFormat = errorsdate
Host = xx.0.1.xx:xxxx
user = xxxx
password = xxxxx
database = xxxxx
debuglevel = 2
StatusFrequency = 60
LoopSleep = 60
DeliveryReport = sms
PhoneID = ozssc-smsd
SMSC = +614xxxxxxxx
BackendRetries = 60

I tried start gammu command line in terminal, it works fine. But when I tried to start system service by using systemctl, it failed.

error query result as:

[root@Centos8Gateway etc]# systemctl status gammu-smsd.service

I'm trying to find out why Centos 8 system service loader not use configured system environment variable? and not provide command line LD lib path parameters as well.

What I missed? Please advise!
