I’m looking for a Mailgun alternative featuring simple SMTP credentials (max 16 characters) and MX record support for around 100 secure subaccounts. Previous options did not meet the requirements.
I have experimented with a custom SMTP solution that meets similar requirements. I implemented a setup using a lightweight, Node.js-based SMTP server that allows for detailed configuration of credentials, including enforcing character limits. It required some manual management initially, but the flexibility in handling DNS and MX records, as well as partitioning for multiple subaccounts, proved beneficial. Although not a direct plug-and-play alternative like some managed services, this approach offers full control over security settings and can be tailored to accommodate the specific character constraints needed.
hey, i tried postal a while ago. its smtp creds fit the bill and setup is not too complicated. might be worth a shot if u can tweak it for your char limit. let me know if u need any more info.
I’ve used Exim in the past for a setup similar to this and found it both flexible and secure. Setting up the system required some custom scripting, but once configured, the process allowed enforcing strict character limits on SMTP credentials while managing MX records effectively. There was a learning curve with the configuration files, but the trade-off was worth it for the level of control achieved. The process also enabled smooth integration of multiple subaccounts, all built on a strong foundation of secure, tailored email handling.
