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.
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. firstname.lastname@example.org).
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".
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.
