The email also confirms that the organisers will be supporting "the British Shalom-Salaam Trust’s emergency appeal for the West Bank and Gaza."
It adds: "This year, Passover will be like never before, with the traditional family Seder night (Passover service) impossible."
The JSG and the Jews for Justice for Palestinians organisations are also listed as co-sponsors of Seder, which takes place on April 9.
The Shalom-Salaam Trust’s website states that it has supported events involving "Palestinians, Israeli Jews, migrants and asylum seekers."
Rabbi Rich has previously sparked anger over his close links to the JVL group, who have repeatedly tried to deny claims of widespread antisemitism in Labour under Mr Corbyn.
The JC also revealed last year how he had invited Mr Corbyn for Friday night dinner.
Rabbi Rich told the JC: "I am now a freelance Jewish educator, acting in a personal capacity, and am happy to offer Jewish teachings and guidance to Jews, and people of other faiths or of no denomination.
"I know many of the individuals involved and may or may not agree with any or some of their political views.
"I am sure you would wish the Jewish community to be sufficiently liberal and mature to enable all Jews to participate in a Seder. After all it was only the wicked child who cut off him or herself from the community."
