The team recently updated how our servers process traffic. Specifically, SMTP (https://www.rfc-editor.org/info/rfc5321/#section-2.3.8) requires 0x0d immediately before 0x0a; a recent patch to Exim against "SMTP smuggling" has altered its behavior when it encounters a missing 0x0d. The team is looking into rolling back this update, but in the meantime, we are suggesting connecting to 45.33.50.34, 43.228.184.6, or 45.33.53.153 instead of the mail.smtp2go.com hostname as a potential workaround.

Our team has been adding new servers to increase capacity, which caused some connection issues and 'processed' emails earlier today. This has been addressed now. Please let us know if you continue seeing any issues.

If you're having trouble connecting to mail.smtp2go.com, try connecting to mail-eu.smtp2go.com instead. Some European locations can't resolve to mail.smtp2go.com. This is a temporary issue that should be fixed shortly. Also, please check that no firewalls are blocking connections to the new IPs we've added to mail.smtp2go.com. The IPs can be found here: https://support.smtp2go.com/hc/en-gb/articles/227835308-Worldwide-Server-Locations-IP-Addresses-and-Email-Routing
