Access denied - Invalid HELO name (See RFC2821 4.1.3)

Edit
vi /etc/exim4/exim4.conf.template

Comments lines
# drop condition = ${if isip{$sender_helo_name}}
# message = Access denied - Invalid HELO name (See RFC2821 4.1.3)

/etc/init.d/exim4 restart

As my server is running Centos, had to restart with

Code: Select all

systemctl restart exim

Worked as a charm ;)

tried this. and the display error disappear but still the mail its not sent to the intended email adress

Hi Peoples unable to find a solution,

This works for me and provides a valid HELO

Edit /etc/exim4/exim4.conf.template

Comment Lines:

Code: Select all

# drop condition = ${if isip{$sender_helo_name}}
# message = Access denied - Invalid HELO name (See RFC2821 4.1.3)

Uncomment Line:

Code: Select all

helo_data = $sender_address_domain

The helo_data is configured to send via relevant domain the email is coming from, so if your hostname is my.domain.com and your logging into my.otherdomain.com to send an email, it must carry the helo domain from my.otherdomain.com not the hostname.

I found in my Exim config this helo_data line was commented by default, it therefor had to be un-commented to send from a multi-domain setup.
