iCloud mail server syntax error
Greetings.
I am using Mac Mail 13.4 on OS Catalina. Our IT help dept uses an email address that begins with a hyphen (-ppc-server@companyname.com) which gets summarily rejected by the iCloud outgoing mail server: smtp.mail.me.com on Mac Mail & IOS mail with a "Bad recipient address syntax" error. Since they are on PCs which do not exhibit this problem, they are not interested in changing addresses for us Mac users.
I do not see any settings in Mail that might allow an exception. Any suggestions on a workaround? Thanks for any help!
Cheers,
Andy
