My outgoing virgin.net emails are going to recipients' spam folders.
Many of the emails I send from my virgin.net account end up in the recipients' spam folders - some do not arrive at all.
The problem has been going on for about a year, but is significantly worse in the past few months.
This is a very long-standing email account used for entirely reputable private correspondence. The majority of recipients are existing contacts with whom I have previously had email exchanges, or to whom I am replying.
I can think of no reason why any of my emails should have been blacklisted as spam. There is no indication that any of my emails accounts have been hacked or spoofed - not even Yahoo...
The problem is so bad now that i have to routinely CC: my own alternative email accounts (e.g. Gmail, Yahoo), and re-send the virgin.net original mails from there if necessary.
Any clues as to why this is happening, and what i can do about it?
