Is it permissible for a sheikh and mosque imam to correspond with women online or meet them to help them, despite his family's fears of fitna and a change in his behavior?

Our advice to your husband is to observe the limits set by Allah and to beware of being lured by Satan, for the temptation of women is a great danger. Speaking with a non-mahram woman unnecessarily is impermissible because it is a source of temptation. How many great evils have occurred due to leniency in speaking and corresponding unnecessarily? As for you, you must think well of your husband and be a helper to him in righteous deeds. Remind him of the obligation to be mindful of Allah and to beware of temptations.
