Not Receiving some emails into my Tiscali inbox

[Thelamb]

Some emails are not getting through checked spam etc and settings still not coming through even though some emails from the same company just a different department are getting received. I woke to a customer support guy from TalkTalk/Tiscali but of no help. Thinking of having to change as it is becoming a problem. Webmail is through safari on iMac.
