Clients

chasquid supports most SMTP clients, but requires them to have some features:

• Support TLS (either STARTTLS or implicit TLS)
• Support the PLAIN authentication method.

All modern clients should support both, and thus have no problems talking to chasquid.

Configuration examples

msmtp

This example is useful as either per-user ~/.msmtprc or system-wide /etc/msmtprc:

account default
tls on
auth on

# Use the SMTP submission port. Many providers block communications to the
# default port 25, but the submission port 587 tends to work just fine.
port 587

# Server hostname.
host SERVER

# Your username (including the domain).
user USER@DOMAIN

# Your password.
password SECRET

Replace the SERVER, USER@DOMAIN and SECRET strings with the appropriate values.

Problematic clients

These clients are known to have issues talking to chasquid:

• ssmtp: does not support the PLAIN authentication method. It is also unmaintained.
  Please use msmtp instead.
