WHM > View Relayers - what action to take?

[spaceman]

Am I right in thinking that the most likely reason that email addresses appear in the View Relayers list is because individual workstations belonging to hosting clients of ours have been infected by viruses which are relaying 3rd party emai messages via their machines (unbeknown to them)?

If so, then I guess the correct course of action is to contact the client(s) and advice them of this?

Or am I wide of the mark here?

Thanks for putting me straight on this one.

Not necessarily. If they are using your server name as their smtp server instead of mail.theirdomain.com (for example using webmail) their e-mail will appear in the list.

That doesn't sound right to me. I am not exactly clear on the subject, but on my server anyone that sends mail via the server ends up on the list.

I'm no expert, but if I send mail via Outlook using mail.mydomain.com it does not appear in the relayers list, but if I use the servername in the smtp field it does. Also, if I send e-mail using my squirrelmail install, which uses the servername as the smtp server, it appears.

Thanks for your comments.

I guess the questions remain:
1. Should I care (i.e. does it matter)?
2. What should I do about it if I do care? Just make sure that the 'offenders' change to using their own domain and not the servername in their SMTP setting?

Thanks.

1. No.
2. Yes. I don't know what the cpanel installed webmail programs use, though, so your only option may be to disable webmail. But it doesn't matter, so I wouldnt worry about it.
