I have recently tried to send an email to my colleague,but received the following error:
Local-part of envelope RCPT address contains utf8 but the remote server did not offer SMTPUTF8
Many suggested to me that you need to avoid the UTF8 option in Gmail. But this option seems no longer available in either the Inbox interface or the "old" Gmail interface.
Also, using the plain-text option, doesn't change anything either. More details about the issue :the mail has no attachments and "special" characters or anything like that should require out of the way encoding.
Also it is important to note that the address contains a - symbol. It seems this is a problem, but there must be a way around it. Anybody have faced such issue before? Any Solution ?
