          You may use



          ^(sips?):([^@]+)(?:@(.+))?$


          See the regex demo.



          Details




          • ^ - start of string


          • (sips?) - Group 1: sip or sips


          • : - a colon


          • ([^@]+) - Group 2: 1 or more chars other than @


          • (?:@(.+))? - an optional non-capturing group:


            • @ - a @ char


            • (.+) - Group 3: any 0+ chars other than line break chars, as many as possible



          • $ - end of string.

          NOTE: if you use the pattern with .matches() method, ^ and $ are redundant and can be removed from the pattern as that method requires a full string match.
