Identifying a process

morning,
i introduce the following sentence:
Code:
"sudo lsof -i | grep smtp"

ang get a list of the processes. two of them i don't know what is the function: 29574 & 29575, with the following indication: "memo" the rest of the processes shown are smtpd. i kill these two processes and they disappear, however, after some minutes they reappear.

No, I asked for:

Code:
sudo lsof -i | grep smtpd

and

Code:
sudo ps aux | grep smtpd

You provided the first one two times.

Please try to follow instructions carefully. Thanks.
