Mass-emailing people?

[mrdini]

Hello,

We need to send an email to everyone in a list (of email addresses). Ideally, we want it to come from a noreply@ address...

However, I can't seem to figure out how to do this in one go. If I create a noreply@ email account, there doesn't seem to be an easy way to add ALL the addresses from a specific address book in one go.

If I create a distribution list at noreply@, the recipients can only too easily reply to that email address and thus spam everyone else on that list which is VERY undesirable.

Thoughts? I realise the best way is to use a proper 3rd party app like phplist (which I'm looking at now), but we do need to send an certain email out this Friday which is a bit too short notice for this.

TIA!

You can create a distribution list that can't be mailed to by external users (or users of your choice), check the wiki article on postfix restrictions. Does that do what you need?

Hmmm... yes, that sounds exactly like what I need, but it doesn't seem to work at all...(emails from 'outside' are still getting through to the distribution list I created)

I've checked the discussion page on the wiki & made the change mentioned in note #2 to no avail.

Which logs would display errors from this? Are the notes up to date for ZCS 4.5?

Did you do a 'postfix reload'?

Si! Both before doing the change mentioned in note #2 & again after.

I'd go through the wiki steps again and check you've entered the correct information. That solution does work.

*Mutters* I've been over it a few times, and can't seem to figure out why it doesn't work....
Mail server is dartagnan.secretcorp.com.
The test account is distro@secretcorp.com (the "real" account is noreply@).

permitted_senders:-

localhost               OK
secretcorp.com            OK
dartagnan.secretcorp.com     OK

protected_recipients:-

distro@secretcorp.com     permitted_senders_list
noreply@secretcorp.com    permitted_senders_list

main.cf:-

permitted_senders_list = check_sender_access hash:/opt/zimbra/postfix/conf/permitted_senders, reject
smtpd_restriction_classes = permitted_senders_list

postfix_recipient_restrictions.cf:-

check_recipient_access hash:/opt/zimbra/postfix/conf/protected_recipients

Thoughts...?

TIA!

the wiki doesn't have the extra 'check_recipient_access' that you do in the following location:

move distro@secretcorp.com to the permitted_senders list (instead of protected_recipients)

noreply@secretcorp.com (the account) is the protected address

Where are you testing from? inside: localhost/secretcorp.com/dartagnan.secretcorp.com? just externally? both?

----
Also, wherever possible - consider putting things in zmmta.cf instead of main.cf, using a CLI command (zmprov etc) or postfonf -e

How do you know when it should be there instead of main.cf? well if it's gone on reboot

It does. Check the Discussion page on the wiki.

Er... no, no. BOTH distro@ & noreply@ are distribution lists that I don't want people to be able to email from "outside". distro@ is the testing account, while noreply@ is the real thing.

Have tried:-

• Telnetting from dartagnan.secretcorp.com to "telnet dartagnan.secretcorp.com 25"
• Emailing distro@secretcorp.com from an external email address

Both doesn't return the required error (i.e. the Zimbra server accepts the email)

Also, wherever possible - consider putting things in zmmta.cf instead of main.cf, using a CLI command (zmprov etc) or postfonf -e

Understood. Will do this modification if we keep this method in the future (chances are I'll set up a proper mass-mailer after sorting this out for Friday)

sigh..that's why they should edit the article and say 'see talk page' if they have something they think debatable...
(I really don't check the discussion pages enough, but I did find this guy today that way: /forums/administrators/11549-iwan.html)

Didn't know distro account was another one you we're trying to protect-you just said:

The test account is distro@secretcorp.com (the "real" account is noreply@).

so I assumed you we're testing sending from there (which is why I asked the next Q after that)
glad that's clarified
