Thanks for the reply, Will. Per your suggestions, I've removed the smtp server from .pinerc settings. The emails certainly aren't hanging anymore (they APPEAR to be sent right away), but there'e a several MINUTE or more delay in receipt at test accounts and I'm now questioning whether some emails are even going through at all. Still waiting for receipt of a few to two different external accounts that I sent quite some time ago...
I also removed the inbox path setting and it simply defaults to that (when viewing through Pine and not looking directly at file).
Removing the sendmail certainly puts messages through faster, but they only seem to be delivered with extensive delay or not at all. What's happening?
Now I'm worried if ANY of the emails I've been sending today (via SMTP or sendmail) are going through at all??
Re: IMAP or SMTP problems....Sorry for confusion. I guess my problem was with SMTP, not IMAP. And now sendmail. I'm able to access incoming email just fine (I hope they're all coming through, anyway!), but am apparently having problems sending.
