I'm still exploring things with my upgrade from Slackware 14.2 to 15.0. This is minor, but annoying. Slackware 14.2 had mailx version 12.5. Slackware 15.0 has mailx version 14.9.23. Here's my issues:
After entering the subject, the "To: mfoley@novatec-inc.com" line pops up. I didn't have that with 12.5 and I'd like to get rid of it. I just entered the recipient on the command line and don't see any reason to see it again right after entering the subject.

Secondly, and more importantly, you can see that I started the mail command at 00:26:06. After hitting the 'dot' to terminate my message, it took over a minutes for the mailer to do something and return to the command line. Why?

I've compared the /etc/nail.rc files on both the 14.2 and 15.0 Slackware systems and they are identical. Likewise, my $HOME/.mailrc file is pretty bare-bones:
What can I do to especially get rid of the 1-minute+ delay in sending messages from the command line?

I suggest to ask on the s-nail mailing list https://lists.sdaoden.eu/mailman/listinfo.cgi/s-mailx , is your request seems very specific.
The s-nail maintainer is very responsive, a friendly and funny guy btw. ;-)

OK, I'll definitely check out that list as this is driving me crazy. Meanwhile, I'll post one more hiccup here in case some LQ mailx user happens to know the answer.

Normally, in 'mail' I could search, e.g. (body serpentine), (body "green serpentine"), (from paypal), etc. Now, I get errors no matter how I do the search:
The man page still shows this as correct:
So, what's up?

I figured out the answer to this last question. Searching on mailx 12.5 was just:
Searching on mailx 14.9.23 is:
It now requires single-quote around the searching directive because, as the error message says, "message specifications are now shell tokens, making it necessary to escape/shell quote parenthesis, e.g., '(from "me")'"

Sheesh! To bad they don't have a compatibility mode!
