Не могу отправить почту из TheBat

Это происходит при отправке почты с ящика на @mail.nnov.ru?

Да, это происходит при отправке с mail.nnov.ru.

Вот что говорит www.spamhaus.org/query/bl?ip=109.184.215.113
109.184.215.113 is listed in the PBL, in the following records:
PBL331446

THE PBL IS NOT A BLACKLIST. You are not blacklisted for spamming or for anything you have done. The PBL is simply a list of ALL of the world's end-user broadband IP space, i.e: IP space normally assigned to broadband/ADSL customers. It is perfectly normal for dynamic IP addresses (DSL, DHCP, cable, dialup) to be listed on the PBL. In fact all IP addresses in the world which are not designated mail server machines *should be* on the PBL.

Ясно, принято. Будем разбираться.

Та же история с Mozilla Thunderbird. Все один в один как описано в предыдущем сообщении
