- acallaghan 5y agoIt works perfectly yes. Maybe it’s not fully blocked, or DO restrict the amount of traffic over :25
- ireflect 5y agoI run a production email server on Digital Ocean and have not experienced this issue. An issue I have experienced is that one email provider (who provides a white label service so that small regional ISPs can include a free email account to their customers) has blocked anything coming from DO's IP block. Ultimately my solution is to route those emails (and only those emails) through mailgun.com. The other 99.9% of my outbound email gets delivered directly to the final email server with no issues.
- WarOnPrivacy 5y ago> one email provider has blocked anything coming from DO's IP block. Me. It is my consistent experience that traffic from DO's netblock rarely (actually never IRL) brings good tidings.
- tux2bsd 5y ago> Even on accounts where SMTP is available I don't know what those accounts are but you shouldn't make statements that are only partially true.
