All,
Just had about 50 emails blocked by Spamcop . . . outbound smtp server provided by Orange in the UK. Return email address provided by my own mail servers. BUT . . .'Preferred emal accont' setting on handset was a third email account (address?)not related to ether of these accounts. Spamcop decided that there was no valid return DNS etc. so blocked the email.
Switching the 'Preferred email account' on the handset to the account I was sending from fixed this.
Clearly some 'cross-contamination' between the 3 accounts / servers - even though Orange Tech Support said this shouldn't cause any problems.
Solution: Make sure that you have the 'Preferred email account' set to be the same as the account your sending from - otherwise you're stuffed.
Pete the phone :icon4:
