Email alerts to a reciptement address that contains an & in the address are not being is the & the issue
example joe&janeblogg@example.com
@jasonf1971 Just curious if you a using quotes when you define the email address. In RFC 5322 the use of the & and other special characters are permitted but then the address needs to be a quoted-string. The dot-atom address of joe.jane.blogg@example.com works without quotes. You may need to have it look like this "joe&janeblogg"@example.com or if there is a dot in there then it would look like "joe&jane".blogg@example.com. Just a thought because the & outside of the quote could be interpreted as something else.
