It's also common to block e-mail that comes directly from hosts on a DSL connection. This might be the problem with paasda.org: # dig paasda.org. mx paasda.org. 60 IN MX 10 mail01.paasda.org. # dig mail01.paasda.org. a mail01.paasda.org. 51 IN A 63.105.28.65 # host 63.105.28.65 Name: sub28-65.member.dsl-only.net Right: a DSL customer. Perhaps they're sending outgoing mail directly from this mailhost instead of via their ISP's mailhost. Piet
