Distribution List Administrator

[marc@ion.lu]

Hellow,

Short version first:
a. I want to use Zimbra for "Newsletters", meaning sending mails to thousands of users at once.
b. This should be doable with distribution lists
c. My first "live" test gave a lot of "Too many hops" errors

Currently, I don't know if I "miss-used" Zimbra for a purpose I shouldn't have and not continue on that issue.
or
The issue was due to the customer's mailserver (not being mine/the one hosting the distribution list).

Anyone else have experience with "Too many hops" error?

Now for the long version:
My goal was to redo a feature for my customers I had on qmail (in the dull pre-Zimbra age). A simple php app only needed to write a text file onto qmail to create an alias (e.g. customer@newsletter.company.com).

I was able to recreate this in Zimbra by using Soap and the Distribution list. I even could add more features like "disabling" an address.

All basic tests went fine, but probably because of the ideal circumstances surrounding them.

My first live test with a customer didn't go well at all.
Most of the 1500 addressees in the distribution list didn't get the mail send from the customer, problem "Too many hops".

Possible problem:
Too many servers involved:
- The customer used his own SMTP server instead of my Zimbra server, this certainly added to the hop-count.
Could this be the issue? As simple as that?

Of course I could configure an account for the customer on my Zimbra to eliminate a few hops.
Should I try this?

If anyone needs more Info, PM me for message headers for a deeper analysis.

Thanks a lot for feedback and help.

Best regards,

Marc M.

Sounds more likely that you have a email loop and the outbound email is being bounced between two servers.

I'm not 100% into counting loops, but the messages eventually arrive at destination, just being rejected because of too many hops (eg: 27 when server limit is 25).

Has this issue been addressed? Have a request to do a similar 'Newsletters' feature using our Zimbra box to outside folks and wondering if I need to be concerned with the 'Too many Hops' issue, or if this was just an issue with Marc's setup possibly. Thanks!
