Rather depends on which registries/registrars had a price promotion attracting abusers recently enough to lead operators to choose to refuse traffic. The long-established gTLDs ccTLDs with a million+ registrations are by and large not aggressivly priced and not blocked. 154342903 com 19562007 cn 17678083 de 12475591 net 10991840 org 10372996 uk 6210775 nl 5702333 ru 5386914 br 4263546 au 4198061 fr 4000000 in 3694658 xyz 3656296 eu 3540175 info 3481481 it 3430626 shop 3395833 ca 3100000 co 3026500 online 2766657 top 2572263 pl 2532060 ch 2100000 us 2079045 es 1881840 pt 1766746 jp 1724239 be 1632933 ir 1571837 store 1510279 site 1480179 at 1474115 cz 1403289 se 1400000 cc 1365524 mx 1336066 za 1320645 dk 1236222 tr 1216203 biz 1112750 vip 1100000 io A longer list is at: https://stats.dnssec-tools.org/#/?top=tlds&tld_tab=3 That includes "dev" and other gTLDs that don't AFAIK have a history of reputation problems. You can also search for price breaks on domain registrations and avoid TLDs that have been aggressively discounted. -- Viktor. _______________________________________________ Postfix-users mailing list -- postfix-users@postfix.org To unsubscribe send an email to postfix-users-le...@postfix.org
