Can't send email to multiple recipients

[MacUser32495]

Today I tried to send a regular update to a group. I got the following error message:

spam, or phishing or malware. Please check or edit your message and try sending it again. (6-1-3-2) ID (61394290101B2E8A)

There is nothing in the email's content or subject that it suspicious or any different from usual. Why can't I send?

I have tried again using webmail instead of Entourage. Same result. Whats going on?? My emails are urgent. Please help quickly.

This is just a customer to customer help forum, everyone here, including myself, are just customers.

The only BT Employees are the forum moderators, who can help with some issues.

How many included in your group?

In case you are either not aware or exceeding it there is a limit of 49 recipients per group email.

Is 49 still the limit with btinternet? Seems a bit antiquated in this day and age.

[gg30340]

You are posting on a three year old thread.

I believe the limit is now 100.

Thanks very much.
