I have five emails accounts with the domain idea-translations I registered via proz. One of those accounts suddenly is flooded with a sort of spam messages apparently sent by me, which are returning to me. An example of one of the spam emails I'm receiving is as follows (i changed my domain and email account name!) is as follows: Mail delivery failed: returning message to sender A message that you sent could not be delivered to one or more of its recipients.

I've already deleted my email account from my hosting provider at Proz.com. As that account was linked to gmail, I deleted the link to gmail. I have AVG security. An additional Kasperky analysis showed no issues at all. What else can I check to stop receiving the spam emails? Or, where can I check if I'm sending spam to unknown people?

Dear Clarisa, This can be really annoying, I am sorry for you. I believe that there is a good chance that your email server is not physically involved in the sending of the messages. However you should probably ask support at proz.com about this. In the mean time you might be able to set up some filter to alleviate the disturbance. I hope that your problem will be solved quickly, and I will appreciate receiving your further information about the future developments. ...

Dear Luca At the same time I noticed the spam, the technical staff at proz.com detected that my email account was sending spams (not even from my computer, but I guess from some remote hosting), and changed my password. It was an almost simuntaneous operation. They were very supportive. I decided, nevertheless to delete temporarily that email account and recover it in a couple of days. I also modified the password of the remaining accounts. Regards ...

Clarisa, the incident most likely has nothing to do with stolen passwords or your account security being compromised in any other way. What you encounter is a so-called 'backscatter': spammers are simply impersonating you, putting your e-mail address in the "From:" line of their mailings, and when spam is rejected by the recipient, it comes back to you because the "From:" line says so. To suppress it, you can establish a so-called SPF (sender policy framework) record in your domain's DNS records...

It may not eliminate the backscatter entirely, but it would reduce it very substantially. Judging by your question, this is probably beyond your IT skill level, but may be able to ask the tech support staff administering your domain to do so. ▲ Collapse | |

I agree with Anton that this sounds like "backscatter". It has happened to me before too, and I have dealt with it by using filters and "white list" email solutions such as Delosmail (I really love Delosmail by the way - great company, very supportive). Thanks for mentioning SPF Anton, I had never heard of that, will keep it in mind in the future. | | | To report site rules violations or get help, contact a site moderator: You can also contact site staff by submitting a support request » "Mail delivery failed: returning message to sender" spam flooding!
