I just installed Thunderbird as my principal email carrier, and I was delighted at how fast and easy it was. Only one problem: it won't send mail. In Troubleshoot I discovered there are two smtp listings for this single account, one default, the other not. How do I delete the non-default one? I'm only guessing this is a conflict problem, but if there are any other known issues for this glitch, please advise. shawhomer@mailfence.com
