A number of emails to me are not getting through, with an undeliverable message being received by the sender.  It appears quite random, as some other emails from people within the same company may get through,  My email server said that it was the DKIM settings on the senders accounts that were not up to date, but senders say it happens to no other email addresses.

The responses are along the following lines:

Could not be delivered because of


Server refused mail at END OF DATA - 550-DKIM: encountered the following problem validating luton.gov.uk: 550 pubkey_dns_syntax


The following recipients were affected: 

email address of recipient.

My server says that they change the SpamAssassin settings, also added senders to a white list and got me to check the DKIM authentication was enabled.

Some have questioned whether my servers DKIM settings are up to date.

Any ideas from the community?

Separately (and I will post it in the viruses section) I keep receiving Win32/Heri warnings via AVG, which is claims to have dealt with, but they pop up frequently.  Is there any chance that this would have any effect on my emails (probably I need to look and see what the Win32/Heri virus is), and/or is there a way to do something so that these do not show up constantly (it can pop up five times in a row, and happens not quite on a daily basis, but quite frequently).

Thanks for the help.

David
