Which mail service is used, where to config it?

[iconberg]

Hello,

i already asked this question in the bitnami forum, but the bitnami engineer mention this setting belongs to the application.
But i cant find it.

Our mail provider opens the firewall on our mail server so espocrm can use it. He sees the wrong line in the header (this can identify the mail as spam) and says we should correct it.

The question:

Hello, i want to change some entry in the mail header, but i cant find wich program is used or find a config for it.

• Which version of the application are you using?: EspoCRM 5.2.5-0
• Please choose how you got the application: 1und1 Cloud Server
• Have you installed any plugin or modified any configuration file?: No
• Describe here your question/suggestion/issue

If we sending mail the mail header contians this line:
Received: from xxx.online-server.cloud ([xxx.xxx.xxx.xxx]:xxxxx helo=admin)
Our mail provider says helo=admin is not correct and can cause problems.
Where to change helo=admin? I cant even find which mailer is used (sendmail/postfix/etc)
Sincerly

Thanks, for the info. If i change this in the file, will an update bring it back?

[tanya]

if this file is changed and is in upgrade package, yes the update will bring it back

Ok, but put it on the todo and make it configurable like server and port in the mail panel.

This parameter should not be available in settings UI.

Why not, port and host are in the UI?
