Just wondering,

Say I have a gmail that forwards to the email on my domain.

Then I set the domain email to forward to the gmail.

Does the smaller inbox fill up within seconds?

Or are there filters in place to recognise and prevent what is happening?

The easy answer...try it :).

 

I have a webmail account and an email client on my system...I don't believe that forwarding is an automatic option for either and my forwarding actions all seem to be independent actions taken by me.

I'm curious about this too, but kind of afraid to try it. :hysterical:

 

The old:

10 GOTO 10

I'm not sure, or perhaps I'm mixing two tech issues, but the email headers may have an incremental counter preventing this imminent doom future.

Setup two email servers and see if you can setup an email loop and watch the logs

Yep, that's why I posted rather than trying it myself - and having to clear up any mess created.

 

Best answers that I can find is that modern email softwares will usually have various ways to spot and prevent any such misconfigured forwarding loops, Autoresponders responding to each other in a loop, etc.

 

(If for no other reason than to protect the providers own servers storage/bandwidth from potentially getting swamped in a kind of DDOS).

 

But it can still happen even though it's not as likely to happen it used to be.
Users will always do odd/unexpected things when changing configurations and mistakes (or malice) will happen..

 

However if such a loop does start up then it will 'break' when a mailbox reaches it's storage limit and then rejects any new emails being received, so that there is nothing new to forward or respond to..
