you are definitely not right.


No, he IS right.  The issue is that while the mail RFC's
don't require rDNS, there are a -few- rather stupid
anti-spam filters out there that do.

As long as you (or one of your users) is not e-mailing to
someone on one of these mailservers your fine.


there are few serwers using rather stupid anti-spams. and they treat it as 
spam. then user complain that mail doesn't get to the receiver.


then i look at logs and paste a fragment about when and why mail wasn't 
received, or (more often) was received by target server.


the next question is for target server's administrator. that are normal 
rules.


not that someone use crap as anti-spam, and i (or you or else) then needs 
to avoid being treated as spam.


this is normal procedure and normal rules, and not reverse.

what mail server admin should do is to receive incoming mail and make sure 
it will go where is should. not install some stupid program and be happy.




even more - quite often mail from my servers, these having reverse DNS 
mappings etc.. are treated as spams. most often by large sh..s like 
gmail, hotmail, , etc... which has spam 
policy as below:


- everything that comes from us or our friends are mail
- everything else is probably spam, if it not, don't care.

No, he IS right.  The issue is that while the mail RFC's

anti-spam filters out there that do.

As long as you (or one of your users) is not e-mailing to
someone on one of these mailservers your fine.

But if you are, your screwed.  We often get this kind of
complaint call from customers who have setup this kind of
deal and -1- person in their organization has -1- coorespondent
they keep getting their mail rejected from.  When we tell
them they have to pay their ISP more money for a static IP address,
whether they do it or not is usually dependent on how
important the particular employee is, who is being screwed
over.

Thanks Nicolas KOWALSKI, I got it. in fact I already
searched around but not reading char by char in the interface. I will take
this into account.

You have not searched in the interface before asking this, have you ?

Settings -> Account -> "Add another email address".

Yes, it can. Just check the headers of my original reply (not this
one) if you do not believe me.

How do I declare my [EMAIL PROTECTED] account as an additional
account in the Gmail interface.
I don't quite understand what you mean. Could you be more specific?
I think it is not able to create in Gmail with different domain  something
like dyndns.com etc
Thank you

With dyndns he won't be able to deliver to many mailservers out there.
while not RFC-mandatory, a static IP address and rDNS are a must now
in most cases.


rDNS is a must? strange but i don't have this in lot of places, and 2 
places with dyndns-like solution (exactly like dyndns.com but done by my 
other machine) - both works without problems.


you are definitely not right.

First declare your [EMAIL PROTECTED] account as an additional
account in the Gmail interface.

Second, configure postfix to send mail from [EMAIL PROTECTED]
through gmail smtp server.

In /etc/postfix/main.cf:

smtp_sender_dependent_authentication = yes
smtp_sasl_auth_enable = yes
smtp_sasl_security_options = noanonymous
sender_dependent_relayhost_maps = hash:/etc/postfix/sender_relay
smtp_sasl_password_maps = hash:/etc/postfix/sender_relay_auth


/etc/postfix/sender_relay:

[EMAIL PROTECTED][smtp.gmail.com]:587


/etc/postfix/sender_relay_auth:

[EMAIL PROTECTED]userA:password_of_userA_on_gmail
