XF 1.5 Zend_Mail_Protocol_Exception: cannot connect to host; error = 110

[adwade]

I have received just two such errors over the last the past 3 weeks. Is this something I should be concerned about and fixing -or- Is it a normal occurrence I don't need to fret over?

Under Email Options
I have Enabled the automated bounced email handler
Connection Type: POP3
Host: pop.zoho.com : 995
Encryption: SSL

If there's something I need to fix, please understand the error messages above are greek to me. So don't get too technical and just assume that I'll understand your advice. Thanxx!

If you have only received two errors in three weeks, it's nothing to be concerned about and is just due to temporary connection issues.

 

[adwade]

Thank you so much!

 

[Paul B]

To clarify, I presume those aren't the only two bounces in three weeks?

Do you see any entries in the bounce log - admin.php?logs/email-bounces ?

 

[adwade]

I think the bounce process has been working alright as I set it up, but I could be mistaken.

My bounce log shows...

and the hunter user is presently in a Email Invalid (bounced) User State.

 

[Paul B]

That confirms the bounce process is working then so yes, you can ignore those sporadic failures.

If they get any worse though you may want to look into it.
