Bad HELO - Host impersonating domain name when http://hostname/roundcube/

Hello,





That was noticed that webmails uses: localhost:587 as an address to connect to SMTP server. And when we work with http://domain.com/roundcube/ and http://hostname/roundcube/ we get an error:

Code:

---

2014-11-30 08:38:32 H=localhost (hostname) [::1] rejected EHLO or HELO hostname: Bad HELO - Host impersonating hostname [hostname]

2014-11-30 08:38:32 H=localhost (hostname) [::1] rejected EHLO or HELO hostname: Bad HELO - Host impersonating hostname [hostname]

The exim.conf does not differentiate on what port is a connection made to: 25 or 587. And it does not differentiate whether or not a connection is made from an authenticated user. As a temporary solution we changed

Code:

---

$config['smtp_server'] = ''localhost';

---

to

Code:

---

$config['smtp_server'] = '%n';

---

in roundcube config.





and

Code:

---

$smtpServerAddress = 'localhost';

---

to

Code:

---

$smtpServerAddress = $_SERVER['SERVER_NAME'];

---

for Squirrelmail.





Is there any better solution?

Code:
