Ok, can you send me an IM (or email) with your email account configuration? (please, do not send your password ;D).

But, if you can send/receive email without avast, why don’t you try:

  1. Close your email client (program).
  2. Start Menu > All programs > avast antivirus
  3. Mail Protection Wizard
  4. Chose ‘other email client than Outlook/Exchange’ (i.e., the second option)
  5. Configure your email accounts (even that ones created in the future).

Will this work?
