problems with email to gmail addresses bouncing back

Everytime I email someone with a gmail address I get this message (I've deleted the recipient's email address):
 
"This is an automatically generated Delivery Status Notification.      
 
Delivery to the following recipients failed permanently:

Any ideas? Have checked all of the settings my end. Also its happening irrespective of what device I use. Thanks in advance.

Thanks, read through the thread you posted but got lost after the second screen. I'm not sure where I find where connection security and SMTP settings are - I attach a screenshot of the settings on my IMac.

Its nothing to do with security settings on your email client, its the lack of SPF or DKIM on the domain you use for your email.

Re: problems with email to gmail addresses bouncing back

Thanks. I've tried to add an SPF record so will wait and see if that has worked. In an earlier thread someone said "also you should change your SMTP connection security to STARTTLS and use port 587" hence my query, but I'll wait now and see if the SPF record does the trick. Thanks for your help.

Re: problems with email to gmail addresses bouncing back

Can we clarify the context here please - what email address / account are you SENDING from...

  • A Plusnet email account or a legacy brand (MAAF) email account
  • you@youraccount.plus.com
  • you@yourdomain.co.uk which is hosted by Plusnet (or MAAF)
  • you@yourdomain.co.uk which is hosted elsewhere which forwards  mail to your Plusnet (or MAAF) mailbox

As for those server settings shown in the screen shot...

  1. SMTP should use Port 587
  2. iMAC does not show STARTTLS but will work it out if you tick "Use SSL"
  3. Under Options... I expect that there will be authentication setting details - these need to be the same as those for the  inbox

In passing POP3 inbound ought to be encrypted, on Port 995 with SSL
