Hello
Following a change of ISP, I had to create "new" Pegaus Mail accounts

I wonder if it would be possible to "import" mails form an "old" account to a "new" one

Thanks for your help and advices

I don't understand what you mean when you say "Following a change of ISP, I had to create "new" Pegaus Mail accounts". A change of ISP should only require that you create new SMTP and POP3 or IMAP host definition files then remove the old ones and select the new ones in the appropriate tabs in Internet options. Existing mail would be untouched. What exactly did you do to create new Pegasus Mail accounts?
