UebiMiau webmail adding @localhostname to email address except first address.
 

UebiMiau webmail adding @localhostname to email address except first address.

I composed and sent an email to following four recipients.
me@anydomain.com, me@yahoo.com, me@myoffice.com, me@meonserver.com

Email arrives at all four domains but To field looks like the one below.
me@anydomain.com; "me@yahoo.com"@myserverhostname.com; "me@myoffice.com"@myserverhostname.com; "me@meonserver.com"@myserverhostname.com

The first email address is always fine, no matter local or public domain but it adds@whateverlocalhostis to all other email addresses, any ideas?

Can you check what the value of append_dot_mydomain in /etc/postfix/main.cf is? It should be no (append_dot_mydomain = no). If you have to change /etc/postfix/main.cf, don't forget to restart Postfix!

Variable append_dot_mydomain was not defined in my original main.cf, output below:

[root@portal postfix]# grep append main.*
main.cf.default:append_dot_mydomain = yes

After adding append_dot_mydomain = no:

[root@portal postfix]# grep append_dot_mydomain main.*
main.cf:append_dot_mydomain = no
main.cf.default:append_dot_mydomain = yes

After I added append_dot_mydomain = no to main.cf, restarted postfix (service postfix restart), sent a test mail but no difference.

Then maybe it's a setting in Uebimiau... Maybe you can find something (a setting) in the web interface?

Any idea how to get the web interface for UebiMiau, I have looked at /webmail/ and /mailuser/ but can't find anything I could tweak with.

The files uebimiau files are in the directory /home/admispconfig/ispconfig/web/webmail/
