I use BT webmail via chrome and am experiencing a sporadic problem when attempting to send some emails - I get the error code - Err Code 553 and the email wont send. This only occurs with some emails - others send OK. I've read through a number of threads on this forum - it appears to be a common issue going back years? I've tried all the suggestions offered by others but can't resolve the problem.
The emails that wont send are plain typed in text (not copied or pasted), no urls, images, unusual content etc - just plain text.
I've checked the IP address - not blacklisted. I've logged out and back in. Turned the modem and hub off and back on. I'm not accessing via VPN.
