Anthony Weiner is still seeking someone to chat with.

The disgraced pol, who began a 21-month sentence Monday in a Massachusetts federal prison for sexting a minor, wants to make sure he doesn’t get too lonely in the clink.

His away message on his personal email addresses gives explicit instructions for staying in touch now that he doesn’t have his famous phone by his side.

“I’ll be away for a while but I would love to stay in touch,” the note reads. “As quaint as it may sound, the best way to reach me is by sending me a letter. When you write, I’ll get you the information about how email might work.

“So please include your full mailing address here and, of course, include it when you write.”

Just don’t think about sending him sticks of dynamite inside a cake. Weiner writes that certain gifts are off-limits: “And although you didn’t ask — yes, you may send me books via Amazon. (No Crock-Pots or washer/dryers, though).”

No matter: We hear the laundry service there is excellent.
