Struggling with EMAIL

Have tried everything, cant get email addresses to work at all?

LOGIN command error: BAD [b’Invalid characters in atom’]
or EOF socket

can you tell us what exactly you are tring to do and how did you do it? More context the better

Yes sorry. I was buried at work today and the post was a cry for help.

I was trying to connect my companies domain and it wasn’t working. So I created a domain knowing that it will work with IMAP.

After putting in all the correct settings I just get an error. Everysingle time.

I’ll post screenshots tomorrow
